d670dcde0a feat: add webhook support for /llm/job endpoint
Add comprehensive webhook notification support for the /llm/job endpoint,
following the same pattern as the existing /crawl/job implementation.

Changes:
- Add webhook_config field to LlmJobPayload model (job.py)
- Implement webhook notifications in process_llm_extraction() with 4
  notification points: success, provider validation failure, extraction
  failure, and general exceptions (api.py)
- Store webhook_config in Redis task data for job tracking
- Initialize WebhookDeliveryService with exponential backoff retry logic
Documentation:
- Add Example 6 to WEBHOOK_EXAMPLES.md showing LLM extraction with webhooks
- Update Flask webhook handler to support both crawl and llm_extraction tasks
- Add TypeScript client examples for LLM jobs
- Add comprehensive examples to docker_webhook_example.py with schema support
- Clarify data structure differences between webhook and API responses

Testing:
- Add test_llm_webhook_feature.py with 7 validation tests (all passing)
- Verify pattern consistency with /crawl/job implementation
- Add implementation guide (WEBHOOK_LLM_JOB_IMPLEMENTATION.md)

f8606f6865 fix: properly serialize Pydantic HttpUrl in webhook config
Use model_dump(mode='json') instead of deprecated dict() method to ensure
Pydantic special types (HttpUrl, UUID, etc.) are properly serialized to
JSON-compatible native Python types.

This fixes webhook delivery failures caused by HttpUrl objects remaining
as Pydantic types in the webhook_config dict, which caused JSON
serialization errors and httpx request failures.

Also update mcp requirement to >=1.18.0 for compatibility.

9f7fee91a9 feat: 🚀 Introduce revolutionary LLMTableExtraction with intelligent chunking for massive tables
BREAKING CHANGE: Table extraction now uses Strategy Design Pattern

This epic commit introduces a game-changing approach to table extraction in Crawl4AI:

 NEW FEATURES:
- LLMTableExtraction: AI-powered extraction for complex HTML tables with rowspan/colspan
- Smart Chunking: Automatically splits massive tables into optimal chunks at row boundaries
- Parallel Processing: Processes multiple chunks simultaneously for blazing-fast extraction
- Intelligent Merging: Seamlessly combines chunk results into complete tables
- Header Preservation: Each chunk maintains context with original headers
- Auto-retry Logic: Built-in resilience with configurable retry attempts

🏗️ ARCHITECTURE:
- Strategy Design Pattern for pluggable table extraction strategies
- ThreadPoolExecutor for concurrent chunk processing
- Token-based chunking with configurable thresholds
- Handles tables without headers gracefully

 PERFORMANCE:
- Process 1000+ row tables without timeout
- Parallel processing with up to 5 concurrent chunks
- Smart token estimation prevents LLM context overflow
- Optimized for providers like Groq for massive tables

🔧 CONFIGURATION:
- enable_chunking: Auto-handle large tables (default: True)
- chunk_token_threshold: When to split (default: 3000 tokens)
- min_rows_per_chunk: Meaningful chunk sizes (default: 10)
- max_parallel_chunks: Concurrent processing (default: 5)

📚 BACKWARD COMPATIBILITY:
- Existing code continues to work unchanged
- DefaultTableExtraction remains the default strategy
- Progressive enhancement approach

This is the future of web table extraction - handling everything from simple tables to massive, complex data grids with merged cells and nested structures. The chunking is completely transparent to users while providing unprecedented scalability.

263d362daa fix(browser_profiler): cross-platform 'q' to quit
This commit introduces platform-specific handling for the 'q' key press to quit the browser profiler, ensuring compatibility with both Windows and Unix-like systems. It also adds a check to see if the browser process has already exited, terminating the input listener if so.

- Implemented `msvcrt` for Windows to capture keyboard input without requiring a newline.
- Retained `termios`, `tty`, and `select` for Unix-like systems.
- Added a check for browser process termination to gracefully exit the input listener.
- Updated logger messages to use colored output for better user experience.

dfcfd8ae57 fix(dispatcher): enable true concurrency for fast-completing tasks in arun_many. REF: #560
The MemoryAdaptiveDispatcher was processing tasks sequentially despite
  max_session_permit > 1 due to fetching only one task per event loop iteration.
  This particularly affected raw:// URLs which complete in microseconds.

  Changes:
  - Replace single task fetch with greedy slot filling using get_nowait()
  - Fill all available slots (up to max_session_permit) immediately
  - Break on empty queue instead of waiting with timeout

  This ensures proper parallelization for all task types, especially
  ultra-fast operations like raw HTML processing.

<summary>🤓 <strong>My Personal Story</strong></summary>
My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didnt meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
I made Crawl4AI open-source for two reasons. First, its my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.

## Installation 🛠️
Crawl4AI offers flexible installation options to suit various use cases. You can install it as a Python package or use Docker.
<details>
<summary>🐍 <strong>Using pip</strong></summary>
Choose the installation option that best fits your needs:
### Basic Installation
For basic web crawling and scraping tasks:
```bash
pip install crawl4ai
crawl4ai-setup # Setup the browser
```
By default, this will install the asynchronous version of Crawl4AI, using Playwright for web crawling.
👉 **Note**: When you install Crawl4AI, the `crawl4ai-setup` should automatically install and set up Playwright. However, if you encounter any Playwright-related errors, you can manually install it using one of these methods:
1. Through the command line:
```bash
playwright install
```
2. If the above doesn't work, try this more specific command:
```bash
python -m playwright install chromium
```
This second method has proven to be more reliable in some cases.
---
### Installation with Synchronous Version
The sync version is deprecated and will be removed in future versions. If you need the synchronous version using Selenium:
```bash
pip install crawl4ai[sync]
```
---
### Development Installation
For contributors who plan to modify the source code:
```bash
git clone https://github.com/unclecode/crawl4ai.git
cd crawl4ai
pip install -e . # Basic installation in editable mode
```
Install optional features:
```bash
pip install -e ".[torch]" # With PyTorch features
pip install -e ".[transformer]" # With Transformer features
pip install -e ".[cosine]" # With cosine similarity features
pip install -e ".[sync]" # With synchronous crawling (Selenium)
pip install -e ".[all]" # Install all optional features
```
</details>

## Version Numbering in Crawl4AI
Crawl4AI follows standard Python version numbering conventions (PEP 440) to help users understand the stability and features of each release.
### Version Numbers Explained
Our version numbers follow this pattern: `MAJOR.MINOR.PATCH` (e.g., 0.4.3)
#### Pre-release Versions
We use different suffixes to indicate development stages:
- `dev` (0.4.3dev1): Development versions, unstable
- `a` (0.4.3a1): Alpha releases, experimental features
- `b` (0.4.3b1): Beta releases, feature complete but needs testing
- `rc` (0.4.3): Release candidates, potential final version
#### Installation
- Regular installation (stable version):
```bash
pip install -U crawl4ai
```
- Install pre-release versions:
```bash
pip install crawl4ai --pre
```
- Install specific version:
```bash
pip install crawl4ai==0.4.3b1
```
#### Why Pre-releases?
We use pre-releases to:
- Test new features in real-world scenarios
- Gather feedback before final releases
- Ensure stability for production users
- Allow early adopters to try new features
For production environments, we recommend using the stable version. For testing new features, you can opt-in to pre-releases using the `--pre` flag.

<summary>🤓 <strong>My Personal Story</strong></summary>
<summary>🤓 <strong>My Personal Story</strong></summary>
My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
I grew up on an Amstrad, thanks to my dad, and never stopped building. In grad school I specialized in NLP and built crawlers for research. Thats where I learned how much extraction matters.
Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didnt meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
In 2023, I needed web-to-Markdown. The “open source” option wanted an account, API token, and $16, and still under-delivered. I went turbo anger mode, built Crawl4AI in days, and it went viral. Now its the most-starred crawler on GitHub.
I made Crawl4AI open-source for two reasons. First, its my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.
I made it open source for **availability**, anyone can use it without a gate. Now Im building the platform for **affordability**, anyone can run serious crawls without breaking the bank. If that resonates, join in, send feedback, or just crawl something amazing.

### Asynchronous Jobs with Webhooks
For long-running crawls or when you want to avoid keeping connections open, use the job queue endpoints. Instead of polling for results, configure a webhook to receive notifications when jobs complete.
#### Why Use Jobs & Webhooks?
- **No Polling Required** - Get notified when crawls complete instead of constantly checking status
- **Better Resource Usage** - Free up client connections while jobs run in the background
- **Scalable Architecture** - Ideal for high-volume crawling with TypeScript/Node.js clients or microservices
- **Reliable Delivery** - Automatic retry with exponential backoff (5 attempts: 1s → 2s → 4s → 8s → 16s)
#### How It Works
1. **Submit Job** → POST to `/crawl/job` with optional `webhook_config`
2. **Get Task ID** → Receive a `task_id` immediately
3. **Job Runs** → Crawl executes in the background
4. **Webhook Fired** → Server POSTs completion notification to your webhook URL
5. **Fetch Results** → If data wasn't included in webhook, GET `/crawl/job/{task_id}`
#### Quick Example
```bash
# Submit a crawl job with webhook notification
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{
"urls": ["https://example.com"],
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
"webhook_data_in_payload": false
}
}'
# Response: {"task_id": "crawl_a1b2c3d4"}
```
**Your webhook receives:**
```json
{
"task_id": "crawl_a1b2c3d4",
"task_type": "crawl",
"status": "completed",
"timestamp": "2025-10-21T10:30:00.000000+00:00",
"urls": ["https://example.com"]
}
```
Then fetch the results:
```bash
curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
```
#### Include Data in Webhook
Set `webhook_data_in_payload: true` to receive the full crawl results directly in the webhook:
```bash
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{
"urls": ["https://example.com"],
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
"webhook_data_in_payload": true
}
}'
```
**Your webhook receives the complete data:**
```json
{
"task_id": "crawl_a1b2c3d4",
"task_type": "crawl",
"status": "completed",
"timestamp": "2025-10-21T10:30:00.000000+00:00",
"urls": ["https://example.com"],
"data": {
"markdown": "...",
"html": "...",
"links": {...},
"metadata": {...}
}
}
```
#### Webhook Authentication
Add custom headers for authentication:
```json
{
"urls": ["https://example.com"],
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/crawl",
"webhook_data_in_payload": false,
"webhook_headers": {
"X-Webhook-Secret": "your-secret-token",
"X-Service-ID": "crawl4ai-prod"
}
}
}
```
#### Global Default Webhook
Configure a default webhook URL in `config.yml` for all jobs:
```yaml
webhooks:
enabled: true
default_url: "https://myapp.com/webhooks/default"
data_in_payload: false
retry:
max_attempts: 5
initial_delay_ms: 1000
max_delay_ms: 32000
timeout_ms: 30000
```
Now jobs without `webhook_config` automatically use the default webhook.
#### Job Status Polling (Without Webhooks)
If you prefer polling instead of webhooks, just omit `webhook_config`:
```bash
# Submit job
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{"urls": ["https://example.com"]}'
# Response: {"task_id": "crawl_xyz"}
# Poll for status
curl http://localhost:11235/crawl/job/crawl_xyz
```
The response includes `status` field: `"processing"`, `"completed"`, or `"failed"`.
> 💡 **Pro tip**: See [WEBHOOK_EXAMPLES.md](./WEBHOOK_EXAMPLES.md) for detailed examples including TypeScript client code, Flask webhook handlers, and failure handling.

# Webhook Feature Examples
This document provides examples of how to use the webhook feature for crawl jobs in Crawl4AI.
## Overview
The webhook feature allows you to receive notifications when crawl jobs complete, eliminating the need for polling. Webhooks are sent with exponential backoff retry logic to ensure reliable delivery.
## Configuration
### Global Configuration (config.yml)
You can configure default webhook settings in `config.yml`:
```yaml
webhooks:
enabled: true
default_url: null # Optional: default webhook URL for all jobs
data_in_payload: false # Optional: default behavior for including data
retry:
max_attempts: 5
initial_delay_ms: 1000 # 1s, 2s, 4s, 8s, 16s exponential backoff
max_delay_ms: 32000
timeout_ms: 30000 # 30s timeout per webhook call
headers: # Optional: default headers to include
User-Agent: "Crawl4AI-Webhook/1.0"
```
## API Usage Examples
### Example 1: Basic Webhook (Notification Only)
Send a webhook notification without including the crawl data in the payload.
**Request:**
```bash
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{
"urls": ["https://example.com"],
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
"webhook_data_in_payload": false
}
}'
```
**Response:**
```json
{
"task_id": "crawl_a1b2c3d4"
}
```
**Webhook Payload Received:**
```json
{
"task_id": "crawl_a1b2c3d4",
"task_type": "crawl",
"status": "completed",
"timestamp": "2025-10-21T10:30:00.000000+00:00",
"urls": ["https://example.com"]
}
```
Your webhook handler should then fetch the results:
```bash
curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
```
### Example 2: Webhook with Data Included
Include the full crawl results in the webhook payload.
**Request:**
```bash
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{
"urls": ["https://example.com"],
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
"webhook_data_in_payload": true
}
}'
```
**Webhook Payload Received:**
```json
{
"task_id": "crawl_a1b2c3d4",
"task_type": "crawl",
"status": "completed",
"timestamp": "2025-10-21T10:30:00.000000+00:00",
"urls": ["https://example.com"],
"data": {
"markdown": "...",
"html": "...",
"links": {...},
"metadata": {...}
}
}
```
### Example 3: Webhook with Custom Headers
Include custom headers for authentication or identification.
**Request:**
```bash
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{
"urls": ["https://example.com"],
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
"webhook_data_in_payload": false,
"webhook_headers": {
"X-Webhook-Secret": "my-secret-token",
"X-Service-ID": "crawl4ai-production"
}
}
}'
```
The webhook will be sent with these additional headers plus the default headers from config.
### Example 4: Failure Notification
When a crawl job fails, a webhook is sent with error details.
**Webhook Payload on Failure:**
```json
{
"task_id": "crawl_a1b2c3d4",
"task_type": "crawl",
"status": "failed",
"timestamp": "2025-10-21T10:30:00.000000+00:00",
"urls": ["https://example.com"],
"error": "Connection timeout after 30s"
}
```
### Example 5: Using Global Default Webhook
If you set a `default_url` in config.yml, jobs without webhook_config will use it:
**config.yml:**
```yaml
webhooks:
enabled: true
default_url: "https://myapp.com/webhooks/default"
data_in_payload: false
```
**Request (no webhook_config needed):**
```bash
curl -X POST http://localhost:11235/crawl/job \
-H "Content-Type: application/json" \
-d '{
"urls": ["https://example.com"]
}'
```
The webhook will be sent to the default URL configured in config.yml.
### Example 6: LLM Extraction Job with Webhook
Use webhooks with the LLM extraction endpoint for asynchronous processing.
**Request:**
```bash
curl -X POST http://localhost:11235/llm/job \
-H "Content-Type: application/json" \
-d '{
"url": "https://example.com/article",
"q": "Extract the article title, author, and publication date",
"schema": "{\"type\": \"object\", \"properties\": {\"title\": {\"type\": \"string\"}, \"author\": {\"type\": \"string\"}, \"date\": {\"type\": \"string\"}}}",
"cache": false,
"provider": "openai/gpt-4o-mini",
"webhook_config": {
"webhook_url": "https://myapp.com/webhooks/llm-complete",
"webhook_data_in_payload": true
}
}'
```
**Response:**
```json
{
"task_id": "llm_1698765432_12345"
}
```
**Webhook Payload Received:**
```json
{
"task_id": "llm_1698765432_12345",
"task_type": "llm_extraction",
"status": "completed",
"timestamp": "2025-10-21T10:30:00.000000+00:00",
"urls": ["https://example.com/article"],
"data": {
"extracted_content": {
"title": "Understanding Web Scraping",
"author": "John Doe",
"date": "2025-10-21"
}
}
}
```
## Webhook Handler Example
Here's a simple Python Flask webhook handler that supports both crawl and LLM extraction jobs:
```python
from flask import Flask, request, jsonify
import requests
app = Flask(__name__)
@app.route('/webhooks/crawl-complete', methods=['POST'])
def handle_crawl_webhook():
payload = request.json
task_id = payload['task_id']
task_type = payload['task_type']
status = payload['status']
if status == 'completed':
# If data not in payload, fetch it
if 'data' not in payload:
# Determine endpoint based on task type
endpoint = 'crawl' if task_type == 'crawl' else 'llm'

# Handle failure...
return jsonify({"status": "received"}), 200
if __name__ == '__main__':
app.run(port=8080)
```
## Retry Logic
The webhook delivery service uses exponential backoff retry logic:
- **Attempts:** Up to 5 attempts by default
- **Delays:** 1s → 2s → 4s → 8s → 16s
- **Timeout:** 30 seconds per attempt
- **Retry Conditions:**
- Server errors (5xx status codes)
- Network errors
- Timeouts
- **No Retry:**
- Client errors (4xx status codes)
- Successful delivery (2xx status codes)
## Benefits
1. **No Polling Required** - Eliminates constant API calls to check job status
2. **Real-time Notifications** - Immediate notification when jobs complete
3. **Reliable Delivery** - Exponential backoff ensures webhooks are delivered
4. **Flexible** - Choose between notification-only or full data delivery
5. **Secure** - Support for custom headers for authentication
6. **Configurable** - Global defaults or per-job configuration
7. **Universal Support** - Works with both `/crawl/job` and `/llm/job` endpoints
## TypeScript Client Example
```typescript
interface WebhookConfig {
webhook_url: string;
webhook_data_in_payload?: boolean;
webhook_headers?: Record<string, string>;
}
interface CrawlJobRequest {
urls: string[];
browser_config?: Record<string, any>;
crawler_config?: Record<string, any>;
webhook_config?: WebhookConfig;
}
interface LLMJobRequest {
url: string;
q: string;
schema?: string;
cache?: boolean;
provider?: string;
webhook_config?: WebhookConfig;
}
async function createCrawlJob(request: CrawlJobRequest) {
const response = await fetch('http://localhost:11235/crawl/job', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(request)
});
const { task_id } = await response.json();
return task_id;
}
async function createLLMJob(request: LLMJobRequest) {
const response = await fetch('http://localhost:11235/llm/job', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(request)
});
const { task_id } = await response.json();
return task_id;
}
// Usage - Crawl Job
const crawlTaskId = await createCrawlJob({
urls: ['https://example.com'],
webhook_config: {
webhook_url: 'https://myapp.com/webhooks/crawl-complete',
webhook_data_in_payload: false,
webhook_headers: {
'X-Webhook-Secret': 'my-secret'
}
}
});
// Usage - LLM Extraction Job
const llmTaskId = await createLLMJob({
url: 'https://example.com/article',
q: 'Extract the main points from this article',
provider: 'openai/gpt-4o-mini',
webhook_config: {
webhook_url: 'https://myapp.com/webhooks/llm-complete',
webhook_data_in_payload: true,
webhook_headers: {
'X-Webhook-Secret': 'my-secret'
}
}
});
```
## Monitoring and Debugging
Webhook delivery attempts are logged at INFO level:
- Successful deliveries
- Retry attempts with delays
- Final failures after max attempts
Check the application logs for webhook delivery status:
```bash
docker logs crawl4ai-container | grep -i webhook
```

# 🚀 Crawl4AI v0.7.3: The Multi-Config Intelligence Update
*August 6, 2025 • 5 min read*
---
Today I'm releasing Crawl4AI v0.7.3—the Multi-Config Intelligence Update. This release brings smarter URL-specific configurations, flexible Docker deployments, important bug fixes, and documentation improvements that make Crawl4AI more robust and production-ready.
## 🎯 What's New at a Glance
- **🕵️ Undetected Browser Support**: Stealth mode for bypassing bot detection systems
- **🎨 Multi-URL Configurations**: Different crawling strategies for different URL patterns in a single batch
- **🐳 Flexible Docker LLM Providers**: Configure LLM providers via environment variables
- **🧠 Memory Monitoring**: Enhanced memory usage tracking and optimization tools
- **📊 Enhanced Table Extraction**: Improved table access and DataFrame conversion
- **💰 GitHub Sponsors**: 4-tier sponsorship system with custom arrangements
- **🔧 Bug Fixes**: Resolved several critical issues for better stability
- **📚 Documentation Updates**: Clearer examples and improved API documentation
## 🎨 Multi-URL Configurations: One Size Doesn't Fit All
**The Problem:** You're crawling a mix of documentation sites, blogs, and API endpoints. Each needs different handling—caching for docs, fresh content for news, structured extraction for APIs. Previously, you'd run separate crawls or write complex conditional logic.
**My Solution:** I implemented URL-specific configurations that let you define different strategies for different URL patterns in a single crawl batch. First match wins, with optional fallback support.
### Technical Implementation
```python
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, MatchMode
# Define specialized configs for different content types
configs = [
# Documentation sites - aggressive caching, include links
CrawlerRunConfig(
url_matcher=["*docs*", "*documentation*"],
cache_mode="write",
markdown_generator_options={"include_links": True}
),
# News/blog sites - fresh content, scroll for lazy loading
CrawlerRunConfig(
url_matcher=lambda url: 'blog' in url or 'news' in url,
cache_mode="bypass",
js_code="window.scrollTo(0, document.body.scrollHeight/2);"
),
# API endpoints - structured extraction
CrawlerRunConfig(
url_matcher=["*.json", "*api*"],
extraction_strategy=LLMExtractionStrategy(
provider="openai/gpt-4o-mini",
extraction_type="structured"
)
),
# Default fallback for everything else
CrawlerRunConfig() # No url_matcher = matches everything
]
# Crawl multiple URLs with appropriate configs
async with AsyncWebCrawler() as crawler:
results = await crawler.arun_many(
urls=[
"https://docs.python.org/3/", # → Uses documentation config
"https://blog.python.org/", # → Uses blog config
"https://api.github.com/users", # → Uses API config
"https://example.com/" # → Uses default config
],
config=configs
)
```
**Matching Capabilities:**
- **String Patterns**: Wildcards like `"*.pdf"`, `"*/blog/*"`
- **Function Matchers**: Lambda functions for complex logic
- **Mixed Matchers**: Combine strings and functions with AND/OR logic
- **Fallback Support**: Default config when nothing matches
**Expected Real-World Impact:**
- **Mixed Content Sites**: Handle blogs, docs, and downloads in one crawl
- **Multi-Domain Crawling**: Different strategies per domain without separate runs
- **Reduced Complexity**: No more if/else forests in your extraction code
- **Better Performance**: Each URL gets exactly the processing it needs
## 🕵️ Undetected Browser Support: Stealth Mode Activated
**The Problem:** Modern websites employ sophisticated bot detection systems. Cloudflare, Akamai, and custom solutions block automated crawlers, limiting access to valuable content.
**My Solution:** I implemented undetected browser support with a flexible adapter pattern. Now Crawl4AI can bypass most bot detection systems using stealth techniques.
### Technical Implementation
```python
from crawl4ai import AsyncWebCrawler, BrowserConfig
# Enable undetected mode for stealth crawling
browser_config = BrowserConfig(
browser_type="undetected", # Use undetected Chrome
headless=True, # Can run headless with stealth
extra_args=[
"--disable-blink-features=AutomationControlled",
"--disable-web-security",
"--disable-features=VizDisplayCompositor"
]
)
async with AsyncWebCrawler(config=browser_config) as crawler:
# This will bypass most bot detection systems
result = await crawler.arun("https://protected-site.com")
if result.success:
print("✅ Successfully bypassed bot detection!")
print(f"Content length: {len(result.markdown)}")
```
**Advanced Anti-Bot Strategies:**
```python
# Combine multiple stealth techniques
from crawl4ai import CrawlerRunConfig
config = CrawlerRunConfig(
# Random user agents and headers
headers={
"Accept-Language": "en-US,en;q=0.9",
"Accept-Encoding": "gzip, deflate, br",
"DNT": "1"
},
# Human-like behavior simulation
js_code="""
// Random mouse movements
const simulateHuman = () => {
const event = new MouseEvent('mousemove', {
clientX: Math.random() * window.innerWidth,
clientY: Math.random() * window.innerHeight
});
document.dispatchEvent(event);
};
setInterval(simulateHuman, 100 + Math.random() * 200);
// Random scrolling
const randomScroll = () => {
const scrollY = Math.random() * (document.body.scrollHeight - window.innerHeight);
window.scrollTo(0, scrollY);
};
setTimeout(randomScroll, 500 + Math.random() * 1000);
""",
# Delay to appear more human
delay_before_return_html=2.0
)
result = await crawler.arun("https://bot-protected-site.com", config=config)
```
**Expected Real-World Impact:**
- **Enterprise Scraping**: Access previously blocked corporate sites and databases
- **Market Research**: Gather data from competitor sites with protection
- **Price Monitoring**: Track e-commerce sites that block automated access
- **Content Aggregation**: Collect news and social media despite anti-bot measures
- **Compliance Testing**: Verify your own site's bot protection effectiveness
## 🧠 Memory Monitoring & Optimization
**The Problem:** Long-running crawl sessions consuming excessive memory, especially when processing large batches or heavy JavaScript sites.
**My Solution:** Built comprehensive memory monitoring and optimization utilities that track usage patterns and provide actionable insights.
### Memory Tracking Implementation
```python
from crawl4ai.memory_utils import MemoryMonitor, get_memory_info
# Monitor memory during crawling
monitor = MemoryMonitor()
async with AsyncWebCrawler() as crawler:
# Start monitoring
monitor.start_monitoring()
# Perform memory-intensive operations
results = await crawler.arun_many([
"https://heavy-js-site.com",
"https://large-images-site.com",
"https://dynamic-content-site.com"
])
# Get detailed memory report
memory_report = monitor.get_report()
print(f"Peak memory usage: {memory_report['peak_mb']:.1f} MB")
print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
# Automatic cleanup suggestions
if memory_report['peak_mb'] > 1000: # > 1GB
print("💡 Consider batch size optimization")
print("💡 Enable aggressive garbage collection")
```
**Expected Real-World Impact:**
- **Production Stability**: Prevent memory-related crashes in long-running services
- **Cost Optimization**: Right-size server resources based on actual usage
- **Performance Tuning**: Identify memory bottlenecks and optimization opportunities
- **Scalability Planning**: Understand memory patterns for horizontal scaling
## 📊 Enhanced Table Extraction
**The Problem:** Table data was accessed through the generic `result.media` interface, making DataFrame conversion cumbersome and unclear.
**My Solution:** Dedicated `result.tables` interface with direct DataFrame conversion and improved detection algorithms.
### New Table Access Pattern
```python
# Old way (deprecated)
# tables_data = result.media.get('tables', [])
# New way (v0.7.3+)
result = await crawler.arun("https://site-with-tables.com")
# Direct table access
if result.tables:
print(f"Found {len(result.tables)} tables")
# Convert to pandas DataFrame instantly
import pandas as pd
for i, table in enumerate(result.tables):
df = pd.DataFrame(table['data'])
print(f"Table {i}: {df.shape[0]} rows × {df.shape[1]} columns")
print(df.head())
# Table metadata
print(f"Source: {table.get('source_xpath', 'Unknown')}")
print(f"Headers: {table.get('headers', [])}")
```
**Expected Real-World Impact:**
- **Data Analysis**: Faster transition from web data to analysis-ready DataFrames
- **ETL Pipelines**: Cleaner integration with data processing workflows
- **Reporting**: Simplified table extraction for automated reporting systems

## 🐳 Docker: Flexible LLM Provider Configuration
**The Problem:** Hardcoded LLM providers in Docker deployments. Want to switch from OpenAI to Groq? Rebuild and redeploy. Testing different models? Multiple Docker images.
**My Solution:** Configure LLM providers via environment variables. Switch providers without touching code or rebuilding images.
### Deployment Flexibility
```bash
# Option 1: Direct environment variables
docker run -d \
-e LLM_PROVIDER="groq/llama-3.2-3b-preview" \
-e GROQ_API_KEY="your-key" \
-p 11235:11235 \
unclecode/crawl4ai:latest
# Option 2: Using .llm.env file (recommended for production)
# Create .llm.env file:
# LLM_PROVIDER=openai/gpt-4o-mini
# OPENAI_API_KEY=your-openai-key
# GROQ_API_KEY=your-groq-key
docker run -d \
--env-file .llm.env \
-p 11235:11235 \
unclecode/crawl4ai:latest
```
Override per request when needed:
```python
# Use default provider from .llm.env
response = requests.post("http://localhost:11235/crawl", json={
"url": "https://example.com",
"extraction_strategy": {"type": "llm"}
})
# Override to use different provider for this specific request
response = requests.post("http://localhost:11235/crawl", json={
"url": "https://complex-page.com",
"extraction_strategy": {
"type": "llm",
"provider": "openai/gpt-4" # Override default
}
})
```
**Expected Real-World Impact:**
- **Cost Optimization**: Use cheaper models for simple tasks, premium for complex
- **A/B Testing**: Compare provider performance without deployment changes
- **Fallback Strategies**: Switch providers on-the-fly during outages
- **Development Flexibility**: Test locally with one provider, deploy with another
- **Secure Configuration**: Keep API keys in `.llm.env` file, not in commands
## 🔧 Bug Fixes & Improvements
This release includes several important bug fixes that improve stability and reliability:
- **URL Matcher Fallback**: Fixed edge cases in URL pattern matching logic
- **Memory Management**: Resolved memory leaks in long-running crawl sessions

This release introduces revolutionary LLM-powered table extraction with intelligent chunking, significant performance improvements for concurrent crawling, enhanced browser management, and critical stability fixes that make Crawl4AI more robust for production workloads.
## 🎯 What's New at a Glance
- **🚀 LLMTableExtraction**: Revolutionary table extraction with intelligent chunking for massive tables
- **⚡ Enhanced Concurrency**: True concurrency improvements for fast-completing tasks in batch operations
- **🧹 Memory Management Refactor**: Streamlined memory utilities and better resource management

## 🚀 LLMTableExtraction: Revolutionary Table Processing
**The Problem:** Complex tables with rowspan, colspan, nested structures, or massive datasets that traditional HTML parsing can't handle effectively. Large tables that exceed token limits crash extraction processes.
**My Solution:** I developed LLMTableExtraction—an intelligent table extraction strategy that uses Large Language Models with automatic chunking to handle tables of any size and complexity.
### Technical Implementation
```python
from crawl4ai import (
AsyncWebCrawler,
CrawlerRunConfig,
LLMConfig,
LLMTableExtraction,
CacheMode
)
# Configure LLM for table extraction
llm_config = LLMConfig(
provider="openai/gpt-4.1-mini",
api_token="env:OPENAI_API_KEY",
temperature=0.1, # Low temperature for consistency
max_tokens=32000
)
# Create intelligent table extraction strategy
table_strategy = LLMTableExtraction(
llm_config=llm_config,
verbose=True,
max_tries=2,
enable_chunking=True, # Handle massive tables
chunk_token_threshold=5000, # Smart chunking threshold
overlap_threshold=100, # Maintain context between chunks
extraction_type="structured" # Get structured data output
)
# Apply to crawler configuration
config = CrawlerRunConfig(
table_extraction_strategy=table_strategy,
cache_mode=CacheMode.BYPASS
)
async with AsyncWebCrawler() as crawler:
# Extract complex tables with intelligence
result = await crawler.arun(
"https://en.wikipedia.org/wiki/List_of_countries_by_GDP",
config=config
)
# Access extracted tables directly
for i, table in enumerate(result.tables):
print(f"Table {i}: {len(table['data'])} rows × {len(table['headers'])} columns")
# Convert to pandas DataFrame instantly
import pandas as pd
df = pd.DataFrame(table['data'], columns=table['headers'])
print(df.head())
```
**Intelligent Chunking for Massive Tables:**
```python
# Handle tables that exceed token limits
large_table_strategy = LLMTableExtraction(
llm_config=llm_config,
enable_chunking=True,
chunk_token_threshold=3000, # Conservative threshold
overlap_threshold=150, # Preserve context
max_concurrent_chunks=3, # Parallel processing
merge_strategy="intelligent" # Smart chunk merging
)
# Process Wikipedia comparison tables, financial reports, etc.
config = CrawlerRunConfig(
table_extraction_strategy=large_table_strategy,
# Target specific table containers
css_selector="div.wikitable, table.sortable",
delay_before_return_html=2.0
)
result = await crawler.arun(
"https://en.wikipedia.org/wiki/Comparison_of_operating_systems",
config=config
)
# Tables are automatically chunked, processed, and merged
print(f"Extracted {len(result.tables)} complex tables")
for table in result.tables:
print(f"Merged table: {len(table['data'])} total rows")
```
**Advanced Features:**
- **Intelligent Chunking**: Automatically splits massive tables while preserving structure
- **Context Preservation**: Overlapping chunks maintain column relationships
- **Parallel Processing**: Concurrent chunk processing for speed
- **Smart Merging**: Reconstructs complete tables from processed chunks
- **Complex Structure Support**: Handles rowspan, colspan, nested tables
- **Metadata Extraction**: Captures table context, captions, and relationships
**Expected Real-World Impact:**
- **Financial Analysis**: Extract complex earnings tables and financial statements
- **Research & Academia**: Process large datasets from Wikipedia, research papers
- **E-commerce**: Handle product comparison tables with complex layouts
- **Government Data**: Extract census data, statistical tables from official sources
- **Competitive Intelligence**: Process competitor pricing and feature tables
## ⚡ Enhanced Concurrency: True Performance Gains
**The Problem:** The `arun_many()` method wasn't achieving true concurrency for fast-completing tasks, leading to sequential processing bottlenecks in batch operations.
**My Solution:** I implemented true concurrency improvements in the dispatcher that enable genuine parallel processing for fast-completing tasks.
### Performance Optimization
```python
# Before v0.7.4: Sequential-like behavior for fast tasks
# After v0.7.4: True concurrency
async with AsyncWebCrawler() as crawler:
# These will now run with true concurrency
urls = [
"https://httpbin.org/delay/1",
"https://httpbin.org/delay/1",
"https://httpbin.org/delay/1",
"https://httpbin.org/delay/1"
]
# Processes in truly parallel fashion
results = await crawler.arun_many(urls)
# Performance improvement: ~4x faster for fast-completing tasks
print(f"Processed {len(results)} URLs with true concurrency")
```
**Expected Real-World Impact:**
- **API Crawling**: 3-4x faster processing of REST endpoints and API documentation
- **Batch URL Processing**: Significant speedup for large URL lists
- **Monitoring Systems**: Faster health checks and status page monitoring
- **Data Aggregation**: Improved performance for real-time data collection
## 🧹 Memory Management Refactor: Cleaner Architecture
**The Problem:** Memory utilities were scattered and difficult to maintain, with potential import conflicts and unclear organization.
**My Solution:** I consolidated all memory-related utilities into the main `utils.py` module, creating a cleaner, more maintainable architecture.
### Improved Memory Handling
```python
# All memory utilities now consolidated
from crawl4ai.utils import get_true_memory_usage_percent, MemoryMonitor
# Enhanced memory monitoring
monitor = MemoryMonitor()
monitor.start_monitoring()
async with AsyncWebCrawler() as crawler:
# Memory-efficient batch processing
results = await crawler.arun_many(large_url_list)
# Get accurate memory metrics
memory_usage = get_true_memory_usage_percent()
memory_report = monitor.get_report()
print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
print(f"Peak usage: {memory_report['peak_mb']:.1f} MB")
```
**Expected Real-World Impact:**
- **Production Stability**: More reliable memory tracking and management
- **Code Maintainability**: Cleaner architecture for easier debugging
- **Import Clarity**: Resolved potential conflicts and import issues
- **Developer Experience**: Simpler API for memory monitoring
## 🔧 Critical Stability Fixes
### Browser Manager Race Condition Resolution
**The Problem:** Concurrent page creation in persistent browser contexts caused "Target page/context closed" errors during high-concurrency operations.
**My Solution:** Implemented thread-safe page creation with proper locking mechanisms.
```python
# Fixed: Safe concurrent page creation
browser_config = BrowserConfig(
browser_type="chromium",
use_persistent_context=True, # Now thread-safe
max_concurrent_sessions=10 # Safely handle concurrent requests
)
async with AsyncWebCrawler(config=browser_config) as crawler:
# These concurrent operations are now stable
tasks = [crawler.arun(url) for url in url_list]
results = await asyncio.gather(*tasks) # No more race conditions
```
### Enhanced Browser Profiler
**The Problem:** Inconsistent keyboard handling across platforms and unreliable quit mechanisms.
**My Solution:** Cross-platform keyboard listeners with improved quit handling.
### Advanced URL Processing
**The Problem:** Raw URL formats (`raw://` and `raw:`) weren't properly handled, and base tag link resolution was incomplete.
**My Solution:** Enhanced URL preprocessing and base tag support.
```python
# Now properly handles all URL formats
urls = [
"https://example.com",
"raw://static-html-content",
"raw:file://local-file.html"
]
# Base tag links are now correctly resolved
config = CrawlerRunConfig(
include_links=True, # Links properly resolved with base tags
resolve_absolute_urls=True
)
```
## 🛡️ Enhanced Proxy Configuration
**The Problem:** Proxy configuration only accepted specific formats, limiting flexibility.
**My Solution:** Enhanced ProxyConfig to support both dictionary and string formats.
```python
# Multiple proxy configuration formats now supported
from crawl4ai import BrowserConfig, ProxyConfig
# String format
proxy_config = ProxyConfig("http://proxy.example.com:8080")
# Dictionary format
proxy_config = ProxyConfig({
"server": "http://proxy.example.com:8080",
"username": "user",
"password": "pass"
})
# Use with crawler
browser_config = BrowserConfig(proxy_config=proxy_config)
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun("https://httpbin.org/ip")
```

Docker Webhook Example for Crawl4AI
This example demonstrates how to use webhooks with the Crawl4AI job queue API.
Instead of polling for results, webhooks notify your application when jobs complete.
Supports both:
- /crawl/job - Raw crawling with markdown extraction
- /llm/job - LLM-powered content extraction
Prerequisites:
1. Crawl4AI Docker container running on localhost:11234
2. Flask installed: pip install flask requests
3. LLM API key configured in .llm.env (for LLM extraction examples)
Usage:
1. Run this script: python docker_webhook_example.py
2. The webhook server will start on http://localhost:8080
3. Jobs will be submitted and webhooks will be received automatically

### [Crawl4AI v0.5.0: Deep Crawling, Scalability, and a New CLI!](releases/0.5.0.md)
My dear friends and crawlers, there you go, this is the release of Crawl4AI v0.5.0! This release brings a wealth of new features, performance improvements, and a more streamlined developer experience. Here's a breakdown of what's new:
**Major New Features:**
* **Deep Crawling:** Explore entire websites with configurable strategies (BFS, DFS, Best-First). Define custom filters and URL scoring for targeted crawls.
* **Memory-Adaptive Dispatcher:** Handle large-scale crawls with ease! Our new dispatcher dynamically adjusts concurrency based on available memory and includes built-in rate limiting.
* **Multiple Crawler Strategies:** Choose between the full-featured Playwright browser-based crawler or a new, *much* faster HTTP-only crawler for simpler tasks.
* **Docker Deployment:** Deploy Crawl4AI as a scalable, self-contained service with built-in API endpoints and optional JWT authentication.
* **Command-Line Interface (CLI):** Interact with Crawl4AI directly from your terminal. Crawl, configure, and extract data with simple commands.
* **LLM Configuration (`LLMConfig`):** A new, unified way to configure LLM providers (OpenAI, Anthropic, Ollama, etc.) for extraction, filtering, and schema generation. Simplifies API key management and switching between models.
**Minor Updates & Improvements:**
* **LXML Scraping Mode:** Faster HTML parsing with `LXMLWebScrapingStrategy`.
* **Proxy Rotation:** Added `ProxyRotationStrategy` with a `RoundRobinProxyStrategy` implementation.
* **PDF Processing:** Extract text, images, and metadata from PDF files.
* **URL Redirection Tracking:** Automatically follows and records redirects.
* **Robots.txt Compliance:** Optionally respect website crawling rules.
* **LLM-Powered Schema Generation:** Automatically create extraction schemas using an LLM.
* **`LLMContentFilter`:** Generate high-quality, focused markdown using an LLM.
* **Improved Error Handling & Stability:** Numerous bug fixes and performance enhancements.
* **Enhanced Documentation:** Updated guides and examples.
**Breaking Changes & Migration:**
This release includes several breaking changes to improve the library's structure and consistency. Here's what you need to know:
* **`arun_many()` Behavior:** Now uses the `MemoryAdaptiveDispatcher` by default. The return type depends on the `stream` parameter in `CrawlerRunConfig`. Adjust code that relied on unbounded concurrency.
* **`max_depth` Location:** Moved to `CrawlerRunConfig` and now controls *crawl depth*.
* **Deep Crawling Imports:** Import `DeepCrawlStrategy` and related classes from `crawl4ai.deep_crawling`.
* **`BrowserContext` API:** Updated; the old `get_context` method is deprecated.
* **Optional Model Fields:** Many data model fields are now optional. Handle potential `None` values.
* **`ScrapingMode` Enum:** Replaced with strategy pattern (`WebScrapingStrategy`, `LXMLWebScrapingStrategy`).
* **`content_filter` Parameter:** Removed from `CrawlerRunConfig`. Use extraction strategies or markdown generators with filters.
* **Removed Functionality:** The synchronous `WebCrawler`, the old CLI, and docs management tools have been removed.
* **Docker:** Significant changes to deployment. See the [Docker documentation](../deploy/docker/README.md).
* **`ssl_certificate.json`:** This file has been removed.
* **Config**: FastFilterChain has been replaced with FilterChain
* **Deep-Crawl**: DeepCrawlStrategy.arun now returns Union[CrawlResultT, List[CrawlResultT], AsyncGenerator[CrawlResultT, None]]
* **Proxy**: Removed synchronous WebCrawler support and related rate limiting configurations
* **LLM Parameters:** Use the new `LLMConfig` object instead of passing `provider`, `api_token`, `base_url`, and `api_base` directly to `LLMExtractionStrategy` and `LLMContentFilter`.
**In short:** Update imports, adjust `arun_many()` usage, check for optional fields, and review the Docker deployment guide.
## License Change
Crawl4AI v0.5.0 updates the license to Apache 2.0 *with a required attribution clause*. This means you are free to use, modify, and distribute Crawl4AI (even commercially), but you *must* clearly attribute the project in any public use or distribution. See the updated `LICENSE` file for the full legal text and specific requirements.

# 🚀 Crawl4AI v0.7.3: The Multi-Config Intelligence Update
*August 6, 2025 • 5 min read*
---
Today I'm releasing Crawl4AI v0.7.3—the Multi-Config Intelligence Update. This release brings smarter URL-specific configurations, flexible Docker deployments, important bug fixes, and documentation improvements that make Crawl4AI more robust and production-ready.
## 🎯 What's New at a Glance
- **Multi-URL Configurations**: Different crawling strategies for different URL patterns in a single batch
- **Flexible Docker LLM Providers**: Configure LLM providers via environment variables
- **Bug Fixes**: Resolved several critical issues for better stability
- **Documentation Updates**: Clearer examples and improved API documentation
## 🎨 Multi-URL Configurations: One Size Doesn't Fit All
**The Problem:** You're crawling a mix of documentation sites, blogs, and API endpoints. Each needs different handling—caching for docs, fresh content for news, structured extraction for APIs. Previously, you'd run separate crawls or write complex conditional logic.
**My Solution:** I implemented URL-specific configurations that let you define different strategies for different URL patterns in a single crawl batch. First match wins, with optional fallback support.
### Technical Implementation
```python
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, MatchMode
# Define specialized configs for different content types
configs = [
# Documentation sites - aggressive caching, include links
CrawlerRunConfig(
url_matcher=["*docs*", "*documentation*"],
cache_mode="write",
markdown_generator_options={"include_links": True}
),
# News/blog sites - fresh content, scroll for lazy loading
CrawlerRunConfig(
url_matcher=lambda url: 'blog' in url or 'news' in url,
cache_mode="bypass",
js_code="window.scrollTo(0, document.body.scrollHeight/2);"
),
# API endpoints - structured extraction
CrawlerRunConfig(
url_matcher=["*.json", "*api*"],
extraction_strategy=LLMExtractionStrategy(
provider="openai/gpt-4o-mini",
extraction_type="structured"
)
),
# Default fallback for everything else
CrawlerRunConfig() # No url_matcher = matches everything
]
# Crawl multiple URLs with appropriate configs
async with AsyncWebCrawler() as crawler:
results = await crawler.arun_many(
urls=[
"https://docs.python.org/3/", # → Uses documentation config
"https://blog.python.org/", # → Uses blog config
"https://api.github.com/users", # → Uses API config
"https://example.com/" # → Uses default config
],
config=configs
)
```
**Matching Capabilities:**
- **String Patterns**: Wildcards like `"*.pdf"`, `"*/blog/*"`
- **Function Matchers**: Lambda functions for complex logic
- **Mixed Matchers**: Combine strings and functions with AND/OR logic
- **Fallback Support**: Default config when nothing matches
**Expected Real-World Impact:**
- **Mixed Content Sites**: Handle blogs, docs, and downloads in one crawl
- **Multi-Domain Crawling**: Different strategies per domain without separate runs
- **Reduced Complexity**: No more if/else forests in your extraction code
- **Better Performance**: Each URL gets exactly the processing it needs
## 🐳 Docker: Flexible LLM Provider Configuration
**The Problem:** Hardcoded LLM providers in Docker deployments. Want to switch from OpenAI to Groq? Rebuild and redeploy. Testing different models? Multiple Docker images.
**My Solution:** Configure LLM providers via environment variables. Switch providers without touching code or rebuilding images.
### Deployment Flexibility
```bash
# Option 1: Direct environment variables
docker run -d \
-e LLM_PROVIDER="groq/llama-3.2-3b-preview" \
-e GROQ_API_KEY="your-key" \
-p 11235:11235 \
unclecode/crawl4ai:latest
# Option 2: Using .llm.env file (recommended for production)
# Create .llm.env file:
# LLM_PROVIDER=openai/gpt-4o-mini
# OPENAI_API_KEY=your-openai-key
# GROQ_API_KEY=your-groq-key
docker run -d \
--env-file .llm.env \
-p 11235:11235 \
unclecode/crawl4ai:latest
```
Override per request when needed:
```python
# Use default provider from .llm.env
response = requests.post("http://localhost:11235/crawl", json={
"url": "https://example.com",
"extraction_strategy": {"type": "llm"}
})
# Override to use different provider for this specific request
response = requests.post("http://localhost:11235/crawl", json={
"url": "https://complex-page.com",
"extraction_strategy": {
"type": "llm",
"provider": "openai/gpt-4" # Override default
}
})
```
**Expected Real-World Impact:**
- **Cost Optimization**: Use cheaper models for simple tasks, premium for complex
- **A/B Testing**: Compare provider performance without deployment changes
- **Fallback Strategies**: Switch providers on-the-fly during outages
- **Development Flexibility**: Test locally with one provider, deploy with another
- **Secure Configuration**: Keep API keys in `.llm.env` file, not in commands
## 🔧 Bug Fixes & Improvements
This release includes several important bug fixes that improve stability and reliability:
- **URL Matcher Fallback**: Fixed edge cases in URL pattern matching logic
- **Memory Management**: Resolved memory leaks in long-running crawl sessions
- **Sitemap Processing**: Fixed redirect handling in sitemap fetching
- **Table Extraction**: Improved table detection and extraction accuracy
- **Error Handling**: Better error messages and recovery from network failures
## 📚 Documentation Enhancements
Based on community feedback, we've updated:
- Clearer examples for multi-URL configuration
- Improved CrawlResult documentation with all available fields
- Fixed typos and inconsistencies across documentation
- Added real-world URLs in examples for better understanding
- New comprehensive demo showcasing all v0.7.3 features

- **Architecture**: Table extraction now uses pluggable strategies
- **Backward Compatible**: Your existing code with `table_score_threshold` continues to work
- **More Power**: Choose from multiple strategies or create your own
- **Same Default Behavior**: By default, uses `DefaultTableExtraction` (same as before)
### Key Points
**Old code still works** - No breaking changes
**Same default behavior** - Uses the proven extraction algorithm
**New capabilities** - Add LLM extraction or custom strategies when needed
**Strategy pattern** - Clean, extensible architecture
## Quick Start
### The Simplest Way (Works Like Before)
If you're already using Crawl4AI, nothing changes:
```python
import asyncio
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
async def extract_tables():
async with AsyncWebCrawler() as crawler:
# This works exactly like before - uses DefaultTableExtraction internally
result = await crawler.arun("https://example.com/data")
# Tables are automatically extracted and available in result.tables
for table in result.tables:
print(f"Table with {len(table['rows'])} rows and {len(table['headers'])} columns")
print(f"Headers: {table['headers']}")
print(f"First row: {table['rows'][0] if table['rows'] else 'No data'}")
asyncio.run(extract_tables())
```
### Using the Old Configuration (Still Supported)
Your existing code with `table_score_threshold` continues to work:
```python
# This old approach STILL WORKS - we maintain backward compatibility
config = CrawlerRunConfig(
table_score_threshold=7 # Internally creates DefaultTableExtraction(table_score_threshold=7)
)
result = await crawler.arun(url, config)
```
## Table Extraction Strategies
### Understanding the Strategy Pattern
The strategy pattern allows you to choose different table extraction algorithms at runtime. Think of it as having different tools in a toolbox - you pick the right one for the job:
- **No explicit strategy?** → Uses `DefaultTableExtraction` automatically (same as v0.7.2 and earlier)
- **Need complex table handling?** → Choose `LLMTableExtraction` (costs money, use sparingly)
- **Want to disable tables?** → Use `NoTableExtraction`
- **Have special requirements?** → Create a custom strategy
### Available Strategies
| Strategy | Description | Use Case | Cost | When to Use |
|----------|-------------|----------|------|-------------|
| `DefaultTableExtraction` | **RECOMMENDED**: Same algorithm as before v0.7.3 | General purpose (default) | Free | **Use this first - handles 95% of cases** |
| `LLMTableExtraction` | AI-powered extraction for complex tables | Tables with complex rowspan/colspan | **$$$ Per API call** | Only when DefaultTableExtraction fails |
| `NoTableExtraction` | Disables table extraction | When tables aren't needed | Free | For text-only extraction |
| Custom strategies | User-defined extraction logic | Specialized requirements | Free | Domain-specific needs |
> **⚠️ CRITICAL COST WARNING for LLMTableExtraction**:
>
> **DO NOT USE `LLMTableExtraction` UNLESS ABSOLUTELY NECESSARY!**
>
> - **Always try `DefaultTableExtraction` first** - It's free and handles most tables perfectly
> - LLM extraction **costs money** with every API call
> - For large tables (100+ rows), LLM extraction can be **very slow**
> - **For large tables**: If you must use LLM, choose fast providers:
> - ✅ **Groq** (fastest inference)
> - ✅ **Cerebras** (optimized for speed)
> - ⚠️ Avoid: OpenAI, Anthropic for large tables (slower)
>
> **🚧 WORK IN PROGRESS**:
> We are actively developing an **advanced non-LLM algorithm** that will handle complex table structures (rowspan, colspan, nested tables) for **FREE**. This will replace the need for costly LLM extraction in most cases. Coming soon!
### DefaultTableExtraction
The default strategy uses a sophisticated scoring system to identify data tables:
```python
from crawl4ai import DefaultTableExtraction, CrawlerRunConfig
# Customize the default extraction
table_strategy = DefaultTableExtraction(
table_score_threshold=7, # Scoring threshold (default: 7)
min_rows=2, # Minimum rows required
min_cols=2, # Minimum columns required
verbose=True # Enable detailed logging
)
config = CrawlerRunConfig(
table_extraction=table_strategy
)
```
#### Scoring System
The scoring system evaluates multiple factors:
| Factor | Score Impact | Description |
|--------|--------------|-------------|
| Has `<thead>` | +2 | Semantic table structure |
| Has `<tbody>` | +1 | Organized table body |
| Has `<th>` elements | +2 | Header cells present |
| Headers in correct position | +1 | Proper semantic structure |
| Consistent column count | +2 | Regular data structure |
| Has caption | +2 | Descriptive caption |
| Has summary | +1 | Summary attribute |
| High text density | +2 to +3 | Content-rich cells |
| Data attributes | +0.5 each | Data-* attributes |
| Nested tables | -3 | Often indicates layout |
| Role="presentation" | -3 | Explicitly non-data |
| Too few rows | -2 | Insufficient data |
### LLMTableExtraction (Use Sparingly!)
**⚠️ WARNING**: Only use this when `DefaultTableExtraction` fails with complex tables!
LLMTableExtraction uses AI to understand complex table structures that traditional parsers struggle with. It automatically handles large tables through intelligent chunking and parallel processing:
```python
from crawl4ai import LLMTableExtraction, LLMConfig, CrawlerRunConfig
# Configure LLM (costs money per call!)
llm_config = LLMConfig(
provider="groq/llama-3.3-70b-versatile", # Fast provider for large tables
api_token="your_api_key",
temperature=0.1
)
# Create LLM extraction strategy with smart chunking
table_strategy = LLMTableExtraction(
llm_config=llm_config,
max_tries=3, # Retry up to 3 times if extraction fails
css_selector="table", # Optional: focus on specific tables
enable_chunking=True, # Automatically chunk large tables (default: True)
chunk_token_threshold=3000, # Split tables larger than this (default: 3000 tokens)
min_rows_per_chunk=10, # Minimum rows per chunk (default: 10)
max_parallel_chunks=5, # Process up to 5 chunks in parallel (default: 5)
verbose=True
)
config = CrawlerRunConfig(
table_extraction=table_strategy
)
result = await crawler.arun(url, config)
```
#### When to Use LLMTableExtraction
**Use ONLY when**:
- Tables have complex merged cells (rowspan/colspan) that break DefaultTableExtraction
- Nested tables that need semantic understanding
- Tables with irregular structures
- You've tried DefaultTableExtraction and it failed
**Never use when**:
- DefaultTableExtraction works (99% of cases)
- Tables are simple or well-structured
- You're processing many pages (costs add up!)
- Tables have 100+ rows (very slow)
#### How Smart Chunking Works
LLMTableExtraction automatically handles large tables through intelligent chunking:
1. **Automatic Detection**: Tables exceeding the token threshold are automatically split
2. **Smart Splitting**: Chunks are created at row boundaries, preserving table structure
3. **Header Preservation**: Each chunk includes the original headers for context
4. **Parallel Processing**: Multiple chunks are processed simultaneously for speed
5. **Intelligent Merging**: Results are merged back into a single, complete table
**Chunking Parameters**:
- `enable_chunking` (default: `True`): Automatically handle large tables
- `chunk_token_threshold` (default: `3000`): When to split tables
- `min_rows_per_chunk` (default: `10`): Ensures meaningful chunk sizes
- `max_parallel_chunks` (default: `5`): Concurrent processing for speed
The chunking is completely transparent - you get the same output format whether the table was processed in one piece or multiple chunks.
#### Performance Optimization for LLMTableExtraction
**Provider Recommendations by Table Size**:
| Table Size | Recommended Providers | Why |
|------------|----------------------|-----|
| Small (<50 rows) | Any provider | Fast enough |
| Medium (50-200 rows) | Groq, Cerebras | Optimized inference |
| Large (200+ rows) | **Groq** (best), Cerebras | Fastest inference + automatic chunking |
| Very Large (500+ rows) | Groq with chunking | Parallel processing keeps it fast |
### NoTableExtraction
Disable table extraction for better performance when tables aren't needed:
```python
from crawl4ai import NoTableExtraction, CrawlerRunConfig
config = CrawlerRunConfig(
table_extraction=NoTableExtraction()
)
# Tables won't be extracted, improving performance
result = await crawler.arun(url, config)
assert len(result.tables) == 0
```
## Extracted Table Structure
Each extracted table contains:
```python
{
"headers": ["Column 1", "Column 2", ...], # Column headers
"rows": [ # Data rows
["Row 1 Col 1", "Row 1 Col 2", ...],
["Row 2 Col 1", "Row 2 Col 2", ...],
],
"caption": "Table Caption", # If present
"summary": "Table Summary", # If present
"metadata": {
"row_count": 10, # Number of rows
"column_count": 3, # Number of columns
"has_headers": True, # Headers detected
"has_caption": True, # Caption exists
"has_summary": False, # Summary exists
"id": "data-table-1", # Table ID if present
"class": "financial-data" # Table class if present
}
}
```
## Configuration Options
### Basic Configuration
```python
config = CrawlerRunConfig(
# Table extraction settings
table_score_threshold=7, # Default threshold (backward compatible)
table_extraction=strategy, # Optional: custom strategy
# Filter what to process
css_selector="main", # Focus on specific area
excluded_tags=["nav", "aside"] # Exclude page sections
)
```
### Advanced Configuration
```python
from crawl4ai import DefaultTableExtraction, CrawlerRunConfig
# Fine-tuned extraction
strategy = DefaultTableExtraction(
table_score_threshold=5, # Lower = more permissive
min_rows=3, # Require at least 3 rows
min_cols=2, # Require at least 2 columns
verbose=True # Detailed logging
)
config = CrawlerRunConfig(
table_extraction=strategy,
css_selector="article.content", # Target specific content
exclude_domains=["ads.com"], # Exclude ad domains
cache_mode=CacheMode.BYPASS # Fresh extraction
)
```
## Working with Extracted Tables
### Convert to Pandas DataFrame
```python
import pandas as pd
async def tables_to_dataframes(url):
async with AsyncWebCrawler() as crawler:
result = await crawler.arun(url)
dataframes = []
for table_data in result.tables:
# Create DataFrame
if table_data['headers']:
df = pd.DataFrame(
table_data['rows'],
columns=table_data['headers']
)
else:
df = pd.DataFrame(table_data['rows'])
# Add metadata as DataFrame attributes
df.attrs['caption'] = table_data.get('caption', '')
df.attrs['metadata'] = table_data.get('metadata', {})
dataframes.append(df)
return dataframes
```
### Filter Tables by Criteria
```python
async def extract_large_tables(url):
async with AsyncWebCrawler() as crawler:
# Configure minimum size requirements
strategy = DefaultTableExtraction(
min_rows=10,
min_cols=3,
table_score_threshold=6
)
config = CrawlerRunConfig(
table_extraction=strategy
)
result = await crawler.arun(url, config)
# Further filter results
large_tables = [
table for table in result.tables
if table['metadata']['row_count'] > 10
and table['metadata']['column_count'] > 3
]
return large_tables
```
### Export Tables to Different Formats
```python
import json
import csv
async def export_tables(url):
async with AsyncWebCrawler() as crawler:
result = await crawler.arun(url)
for i, table in enumerate(result.tables):
# Export as JSON
with open(f'table_{i}.json', 'w') as f:
json.dump(table, f, indent=2)
# Export as CSV
with open(f'table_{i}.csv', 'w', newline='') as f:
writer = csv.writer(f)
if table['headers']:
writer.writerow(table['headers'])
writer.writerows(table['rows'])
# Export as Markdown
with open(f'table_{i}.md', 'w') as f:
# Write headers
if table['headers']:
f.write('| ' + ' | '.join(table['headers']) + ' |\n')
f.write('|' + '---|' * len(table['headers']) + '\n')
# Write rows
for row in table['rows']:
f.write('| ' + ' | '.join(str(cell) for cell in row) + ' |\n')
```
## Creating Custom Strategies
Extend `TableExtractionStrategy` to create custom extraction logic:
### Example: Financial Table Extractor
```python
from crawl4ai import TableExtractionStrategy
from typing import List, Dict, Any
import re
class FinancialTableExtractor(TableExtractionStrategy):
"""Extract tables containing financial data."""
def __init__(self, currency_symbols=None, require_numbers=True, **kwargs):
super().__init__(**kwargs)
self.currency_symbols = currency_symbols or ['$', '', '£', '¥']
self.require_numbers = require_numbers
self.number_pattern = re.compile(r'\d+[,.]?\d*')
def extract_tables(self, element, **kwargs):
tables_data = []
for table in element.xpath(".//table"):
# Check if table contains financial indicators
table_text = ''.join(table.itertext())
# Must contain currency symbols
has_currency = any(sym in table_text for sym in self.currency_symbols)
if not has_currency:
continue
# Must contain numbers if required
if self.require_numbers:
numbers = self.number_pattern.findall(table_text)
if len(numbers) < 3: # Arbitrary minimum
continue
# Extract the table data
table_data = self._extract_financial_data(table)
if table_data:
tables_data.append(table_data)
return tables_data
def _extract_financial_data(self, table):
"""Extract and clean financial data from table."""
headers = []
rows = []
# Extract headers
for th in table.xpath(".//thead//th | .//tr[1]//th"):
headers.append(th.text_content().strip())
# Extract and clean rows
for tr in table.xpath(".//tbody//tr | .//tr[position()>1]"):
row = []
for td in tr.xpath(".//td"):
text = td.text_content().strip()
# Clean currency formatting
text = re.sub(r'[$€£¥,]', '', text)
row.append(text)
if row:
rows.append(row)
return {
"headers": headers,
"rows": rows,
"caption": self._get_caption(table),
"summary": table.get("summary", ""),
"metadata": {
"type": "financial",
"row_count": len(rows),
"column_count": len(headers) or len(rows[0]) if rows else 0
}
}
def _get_caption(self, table):
caption = table.xpath(".//caption/text()")
return caption[0].strip() if caption else ""
# Usage
strategy = FinancialTableExtractor(
currency_symbols=['$', 'EUR'],
require_numbers=True
)
config = CrawlerRunConfig(
table_extraction=strategy
)
```
### Example: Specific Table Extractor
```python
class SpecificTableExtractor(TableExtractionStrategy):
"""Extract only tables matching specific criteria."""
def __init__(self,
required_headers=None,
id_pattern=None,
class_pattern=None,
**kwargs):
super().__init__(**kwargs)
self.required_headers = required_headers or []
self.id_pattern = id_pattern
self.class_pattern = class_pattern
def extract_tables(self, element, **kwargs):
tables_data = []
for table in element.xpath(".//table"):
# Check ID pattern
if self.id_pattern:
table_id = table.get('id', '')
if not re.match(self.id_pattern, table_id):
continue
# Check class pattern
if self.class_pattern:
table_class = table.get('class', '')
if not re.match(self.class_pattern, table_class):
continue
# Extract headers to check requirements
headers = self._extract_headers(table)
# Check if required headers are present
if self.required_headers:
if not all(req in headers for req in self.required_headers):
continue
# Extract full table data
table_data = self._extract_table_data(table, headers)
tables_data.append(table_data)
return tables_data
```
## Combining with Other Strategies
Table extraction works seamlessly with other Crawl4AI strategies:
```python
from crawl4ai import (
AsyncWebCrawler,
CrawlerRunConfig,
DefaultTableExtraction,
LLMExtractionStrategy,
JsonCssExtractionStrategy
)
async def combined_extraction(url):
async with AsyncWebCrawler() as crawler:
config = CrawlerRunConfig(
# Table extraction
table_extraction=DefaultTableExtraction(
table_score_threshold=6,
min_rows=2
),
# CSS-based extraction for specific elements
extraction_strategy=JsonCssExtractionStrategy({
"title": "h1",
"summary": "p.summary",
"date": "time"
}),
# Focus on main content
css_selector="main.content"
)
result = await crawler.arun(url, config)
# Access different extraction results
tables = result.tables # Table data
structured = json.loads(result.extracted_content) # CSS extraction
return {
"tables": tables,
"structured_data": structured,
"markdown": result.markdown
}
```
## Performance Considerations
### Optimization Tips
1. **Disable when not needed**: Use `NoTableExtraction` if tables aren't required
2. **Target specific areas**: Use `css_selector` to limit processing scope
3. **Set minimum thresholds**: Filter out small/irrelevant tables early
4. **Cache results**: Use appropriate cache modes for repeated extractions
```python
# Optimized configuration for large pages
config = CrawlerRunConfig(
# Only process main content area
css_selector="article.main-content",
# Exclude navigation and sidebars
excluded_tags=["nav", "aside", "footer"],
# Higher threshold for stricter filtering
table_extraction=DefaultTableExtraction(
table_score_threshold=8,
min_rows=5,
min_cols=3
),
# Enable caching for repeated access
cache_mode=CacheMode.ENABLED
)
```
## Migration Guide
### Important: Your Code Still Works!
**No changes required!** The transition to the strategy pattern is **fully backward compatible**.
### How It Works Internally
#### v0.7.2 and Earlier
```python
# Old way - directly passing table_score_threshold
config = CrawlerRunConfig(
table_score_threshold=7
)
# Internally: No strategy pattern, direct implementation
```
#### v0.7.3+ (Current)
```python
# Old way STILL WORKS - we handle it internally
config = CrawlerRunConfig(
table_score_threshold=7
)
# Internally: Automatically creates DefaultTableExtraction(table_score_threshold=7)
```
### Taking Advantage of New Features
While your old code works, you can now use the strategy pattern for more control:
```python
# Option 1: Keep using the old way (perfectly fine!)
config = CrawlerRunConfig(
table_score_threshold=7 # Still supported
)
# Option 2: Use the new strategy pattern (more flexibility)
from crawl4ai import DefaultTableExtraction
strategy = DefaultTableExtraction(
table_score_threshold=7,
min_rows=2, # New capability!
min_cols=2 # New capability!
)
config = CrawlerRunConfig(
table_extraction=strategy
)
# Option 3: Use advanced strategies when needed
from crawl4ai import LLMTableExtraction, LLMConfig
# Only for complex tables that DefaultTableExtraction can't handle
# Automatically handles large tables with smart chunking
llm_strategy = LLMTableExtraction(
llm_config=LLMConfig(
provider="groq/llama-3.3-70b-versatile",
api_token="your_key"
),
max_tries=3,
enable_chunking=True, # Automatically chunk large tables
chunk_token_threshold=3000, # Chunk when exceeding 3000 tokens
max_parallel_chunks=5 # Process up to 5 chunks in parallel
)
config = CrawlerRunConfig(
table_extraction=llm_strategy # Advanced extraction with automatic chunking
)
```
### Summary
-**No breaking changes** - Old code works as-is
-**Same defaults** - DefaultTableExtraction is automatically used
-**Gradual adoption** - Use new features when you need them
-**Full compatibility** - result.tables structure unchanged
## Best Practices
### 1. Choose the Right Strategy (Cost-Conscious Approach)
**Decision Flow**:
```
1. Do you need tables?
→ No: Use NoTableExtraction
→ Yes: Continue to #2
2. Try DefaultTableExtraction first (FREE)
→ Works? Done! ✅
→ Fails? Continue to #3
3. Is the table critical and complex?
→ No: Accept DefaultTableExtraction results
→ Yes: Continue to #4
4. Use LLMTableExtraction (COSTS MONEY)
→ Small table (<50 rows): Any LLM provider
→ Large table (50+ rows): Use Groq or Cerebras
→ Very large (500+ rows): Reconsider - maybe chunk the page
```
**Strategy Selection Guide**:
- **DefaultTableExtraction**: Use for 99% of cases - it's free and effective
- **LLMTableExtraction**: Only for complex tables with merged cells that break DefaultTableExtraction
- **NoTableExtraction**: When you only need text/markdown content
- **Custom Strategy**: For specialized requirements (financial, scientific, etc.)
### 2. Validate Extracted Data
```python
def validate_table(table):
"""Validate table data quality."""
# Check structure
if not table.get('rows'):
return False
# Check consistency
if table.get('headers'):
expected_cols = len(table['headers'])
for row in table['rows']:
if len(row) != expected_cols:
return False
# Check minimum content
total_cells = sum(len(row) for row in table['rows'])
non_empty = sum(1 for row in table['rows']
for cell in row if cell.strip())
if non_empty / total_cells < 0.5: # Less than 50% non-empty
return False
return True
# Filter valid tables
valid_tables = [t for t in result.tables if validate_table(t)]
```
### 3. Handle Edge Cases
```python
async def robust_table_extraction(url):
"""Extract tables with error handling."""
async with AsyncWebCrawler() as crawler:
try:
config = CrawlerRunConfig(
table_extraction=DefaultTableExtraction(
table_score_threshold=6,
verbose=True
)
)
result = await crawler.arun(url, config)
if not result.success:
print(f"Crawl failed: {result.error}")
return []
# Process tables safely
processed_tables = []
for table in result.tables:
try:
# Validate and process
if validate_table(table):
processed_tables.append(table)
except Exception as e:
print(f"Error processing table: {e}")
continue
return processed_tables
except Exception as e:
print(f"Extraction error: {e}")
return []
```
## Troubleshooting
### Common Issues and Solutions
| Issue | Cause | Solution |
|-------|-------|----------|
| No tables extracted | Score too high | Lower `table_score_threshold` |
| Layout tables included | Score too low | Increase `table_score_threshold` |
| Missing tables | CSS selector too specific | Broaden or remove `css_selector` |
| Incomplete data | Complex table structure | Create custom strategy |
| Performance issues | Processing entire page | Use `css_selector` to limit scope |
### Debug Logging
Enable verbose logging to understand extraction decisions:
```python
import logging
# Configure logging
logging.basicConfig(level=logging.DEBUG)
# Enable verbose mode in strategy
strategy = DefaultTableExtraction(
table_score_threshold=7,
verbose=True # Detailed extraction logs
)
config = CrawlerRunConfig(
table_extraction=strategy,
verbose=True # General crawler logs
)
```

# Migration Guide: Table Extraction v0.7.3
## Overview
Version 0.7.3 introduces the **Table Extraction Strategy Pattern**, providing a more flexible and extensible approach to table extraction while maintaining full backward compatibility.
## What's New
### Strategy Pattern Implementation
Table extraction now follows the same strategy pattern used throughout Crawl4AI:
- **Consistent Architecture**: Aligns with extraction, chunking, and markdown strategies
- **Extensibility**: Easy to create custom table extraction strategies
- **Better Separation**: Table logic moved from content scraping to dedicated module
- **Full Control**: Fine-grained control over table detection and extraction
### New Classes
```python
from crawl4ai import (
TableExtractionStrategy, # Abstract base class
DefaultTableExtraction, # Current implementation (default)
NoTableExtraction # Explicitly disable extraction
)
```
## Backward Compatibility
**✅ All existing code continues to work without changes.**
### No Changes Required
If your code looks like this, it will continue to work:
```python
# This still works exactly the same
config = CrawlerRunConfig(
table_score_threshold=7
)
result = await crawler.arun(url, config)
tables = result.tables # Same structure, same data
```
### What Happens Behind the Scenes
When you don't specify a `table_extraction` strategy:
1. `CrawlerRunConfig` automatically creates `DefaultTableExtraction`
2. It uses your `table_score_threshold` parameter
3. Tables are extracted exactly as before
4. Results appear in `result.tables` with the same structure
## New Capabilities
### 1. Explicit Strategy Configuration
You can now explicitly configure table extraction:
```python
# New: Explicit control
strategy = DefaultTableExtraction(
table_score_threshold=7,
min_rows=2, # New: minimum row filter
min_cols=2, # New: minimum column filter
verbose=True # New: detailed logging
)
config = CrawlerRunConfig(
table_extraction=strategy
)
```
### 2. Disable Table Extraction
Improve performance when tables aren't needed:
```python
# New: Skip table extraction entirely
config = CrawlerRunConfig(
table_extraction=NoTableExtraction()
)
# No CPU cycles spent on table detection/extraction
```
### 3. Custom Extraction Strategies
Create specialized extractors:
```python
class MyTableExtractor(TableExtractionStrategy):
def extract_tables(self, element, **kwargs):
# Custom extraction logic
return custom_tables
config = CrawlerRunConfig(
table_extraction=MyTableExtractor()
)
```
## Migration Scenarios
### Scenario 1: Basic Usage (No Changes Needed)
**Before (v0.7.2):**
```python
config = CrawlerRunConfig()
result = await crawler.arun(url, config)
for table in result.tables:
print(table['headers'])
```
**After (v0.7.3):**
```python
# Exactly the same - no changes required
config = CrawlerRunConfig()
result = await crawler.arun(url, config)
for table in result.tables:
print(table['headers'])
```
### Scenario 2: Custom Threshold (No Changes Needed)
**Before (v0.7.2):**
```python
config = CrawlerRunConfig(
table_score_threshold=5
)
```
**After (v0.7.3):**
```python
# Still works the same
config = CrawlerRunConfig(
table_score_threshold=5
)
# Or use new explicit approach for more control
strategy = DefaultTableExtraction(
table_score_threshold=5,
min_rows=2 # Additional filtering
)
config = CrawlerRunConfig(
table_extraction=strategy
)
```
### Scenario 3: Advanced Filtering (New Feature)
**Before (v0.7.2):**
```python
# Had to filter after extraction
config = CrawlerRunConfig(
table_score_threshold=5
)
result = await crawler.arun(url, config)
# Manual filtering
large_tables = [
t for t in result.tables
if len(t['rows']) >= 5 and len(t['headers']) >= 3
]
```
**After (v0.7.3):**
```python
# Filter during extraction (more efficient)
strategy = DefaultTableExtraction(
table_score_threshold=5,
min_rows=5,
min_cols=3
)
config = CrawlerRunConfig(
table_extraction=strategy
)
result = await crawler.arun(url, config)
# result.tables already filtered
```
## Code Organization Changes
### Module Structure
**Before (v0.7.2):**
```
crawl4ai/
content_scraping_strategy.py
- LXMLWebScrapingStrategy
- is_data_table() # Table detection
- extract_table_data() # Table extraction
```
**After (v0.7.3):**
```
crawl4ai/
content_scraping_strategy.py
- LXMLWebScrapingStrategy
# Table methods removed, uses strategy
table_extraction.py (NEW)
- TableExtractionStrategy # Base class
- DefaultTableExtraction # Moved logic here
- NoTableExtraction # New option
```
### Import Changes
**New imports available (optional):**
```python
# These are now available but not required for existing code
from crawl4ai import (
TableExtractionStrategy,
DefaultTableExtraction,
NoTableExtraction
)
```
## Performance Implications
### No Performance Impact
For existing code, performance remains identical:
- Same extraction logic
- Same scoring algorithm
- Same processing time
### Performance Improvements Available
New options for better performance:
```python
# Skip tables entirely (faster)
config = CrawlerRunConfig(
table_extraction=NoTableExtraction()
)
# Process only specific areas (faster)
config = CrawlerRunConfig(
css_selector="main.content",
table_extraction=DefaultTableExtraction(
min_rows=5, # Skip small tables
min_cols=3
)
)
```
## Testing Your Migration
### Verification Script
Run this to verify your extraction still works:
```python
import asyncio
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
async def verify_extraction():
url = "your_url_here"
async with AsyncWebCrawler() as crawler:
# Test 1: Old approach
config_old = CrawlerRunConfig(
table_score_threshold=7
)
result_old = await crawler.arun(url, config_old)
# Test 2: New explicit approach
from crawl4ai import DefaultTableExtraction
config_new = CrawlerRunConfig(
table_extraction=DefaultTableExtraction(
table_score_threshold=7
)
)
result_new = await crawler.arun(url, config_new)
# Compare results
assert len(result_old.tables) == len(result_new.tables)
print(f"✓ Both approaches extracted {len(result_old.tables)} tables")
# Verify structure
for old, new in zip(result_old.tables, result_new.tables):
assert old['headers'] == new['headers']
assert old['rows'] == new['rows']
print("✓ Table content identical")
asyncio.run(verify_extraction())
```
## Deprecation Notes
### No Deprecations
- All existing parameters continue to work
- `table_score_threshold` in `CrawlerRunConfig` is still supported
- No breaking changes
### Internal Changes (Transparent to Users)
- `LXMLWebScrapingStrategy.is_data_table()` - Moved to `DefaultTableExtraction`
- `LXMLWebScrapingStrategy.extract_table_data()` - Moved to `DefaultTableExtraction`
These methods were internal and not part of the public API.
## Benefits of Upgrading
While not required, using the new pattern provides:
1. **Better Control**: Filter tables during extraction, not after
2. **Performance Options**: Skip extraction when not needed
3. **Extensibility**: Create custom extractors for specific needs
4. **Consistency**: Same pattern as other Crawl4AI strategies
5. **Future-Proof**: Ready for upcoming advanced strategies
## Troubleshooting
### Issue: Different Number of Tables
**Cause**: Threshold or filtering differences
**Solution**:
```python
# Ensure same threshold
strategy = DefaultTableExtraction(
table_score_threshold=7, # Match your old setting
min_rows=0, # No filtering (default)
min_cols=0 # No filtering (default)
)
```
### Issue: Import Errors
**Cause**: Using new classes without importing
**Solution**:
```python
# Add imports if using new features
from crawl4ai import (
DefaultTableExtraction,
NoTableExtraction,
TableExtractionStrategy
)
```
### Issue: Custom Strategy Not Working
**Cause**: Incorrect method signature
**Solution**:
```python
class CustomExtractor(TableExtractionStrategy):
def extract_tables(self, element, **kwargs): # Correct signature
# Not: extract_tables(self, html)
# Not: extract(self, element)
return tables_list
```
## Getting Help
If you encounter issues:
1. Check your `table_score_threshold` matches previous settings
2. Verify imports if using new classes
3. Enable verbose logging: `DefaultTableExtraction(verbose=True)`
4. Review the [Table Extraction Documentation](../core/table_extraction.md)
5. Check [examples](../examples/table_extraction_example.py)
## Summary
-**Full backward compatibility** - No code changes required
-**Same results** - Identical extraction behavior by default
-**New options** - Additional control when needed
-**Better architecture** - Consistent with Crawl4AI patterns
-**Ready for future** - Foundation for advanced strategies
The migration to v0.7.3 is seamless with no required changes while providing new capabilities for those who need them.

This directory contains a comprehensive test script for the webhook feature implementation.
## Overview
The `test_webhook_feature.sh` script automates the entire process of testing the webhook feature:
1. ✅ Fetches and switches to the webhook feature branch
2. ✅ Activates the virtual environment
3. ✅ Installs all required dependencies
4. ✅ Starts Redis server in background
5. ✅ Starts Crawl4AI server in background
6. ✅ Runs webhook integration test
7. ✅ Verifies job completion via webhook
8. ✅ Cleans up and returns to original branch
## Prerequisites
- Python 3.10+
- Virtual environment already created (`venv/` in project root)
- Git repository with the webhook feature branch
- `redis-server` (script will attempt to install if missing)
- `curl` and `lsof` commands available
## Usage
### Quick Start
From the project root:
```bash
./tests/test_webhook_feature.sh
```
Or from the tests directory:
```bash
cd tests
./test_webhook_feature.sh
```
### What the Script Does
#### Step 1: Branch Management
- Saves your current branch
- Fetches the webhook feature branch from remote
- Switches to the webhook feature branch
#### Step 2: Environment Setup
- Activates your existing virtual environment
- Installs dependencies from `deploy/docker/requirements.txt`
- Installs Flask for the webhook receiver
#### Step 3: Service Startup
- Starts Redis server on port 6379
- Starts Crawl4AI server on port 11235
- Waits for server health check to pass
#### Step 4: Webhook Test
- Creates a webhook receiver on port 8080
- Submits a crawl job for `https://example.com` with webhook config
- Waits for webhook notification (60s timeout)
- Verifies webhook payload contains expected data
#### Step 5: Cleanup
- Stops webhook receiver
- Stops Crawl4AI server
- Stops Redis server
- Returns to your original branch
## Expected Output

```
## Troubleshooting
### Server Failed to Start
If the server fails to start, check the logs:
```bash
tail -100 /tmp/crawl4ai_server.log
```
Common issues:
- Port 11235 already in use: `lsof -ti:11235 | xargs kill -9`
- Missing dependencies: Check that all packages are installed
### Redis Connection Failed
Check if Redis is running:
```bash
redis-cli ping
# Should return: PONG
```
If not running:
```bash
redis-server --port 6379 --daemonize yes
```
### Webhook Not Received
The script has a 60-second timeout for webhook delivery. If the webhook isn't received:
1. Check server logs: `/tmp/crawl4ai_server.log`
2. Verify webhook receiver is running on port 8080
3. Check network connectivity between components
### Script Interruption
If the script is interrupted (Ctrl+C), cleanup happens automatically via trap. The script will:
- Kill all background processes
- Stop Redis
- Return to your original branch
To manually cleanup if needed:
```bash
# Kill processes by port
lsof -ti:11235 | xargs kill -9 # Server
lsof -ti:8080 | xargs kill -9 # Webhook receiver
lsof -ti:6379 | xargs kill -9 # Redis
# Return to your branch
git checkout develop # or your branch name
```
## Testing Different URLs
To test with a different URL, modify the script or create a custom test:
```python
payload = {
"urls": ["https://your-url-here.com"],
"browser_config": {"headless": True},
"crawler_config": {"cache_mode": "bypass"},
"webhook_config": {
"webhook_url": "http://localhost:8080/webhook",
"webhook_data_in_payload": True
}
}
```
## Files Generated
The script creates temporary files:
- `/tmp/crawl4ai_server.log` - Server output logs
- `/tmp/test_webhook.py` - Webhook test Python script
These are not cleaned up automatically so you can review them after the test.
## Exit Codes
- `0` - All tests passed successfully
- `1` - Test failed (check output for details)
## Safety Features
- ✅ Automatic cleanup on exit, interrupt, or error
- ✅ Returns to original branch on completion
- ✅ Kills all background processes
- ✅ Comprehensive error handling
- ✅ Colored output for easy reading
- ✅ Detailed logging at each step
## Notes
- The script uses `set -e` to exit on any command failure
- All background processes are tracked and cleaned up
- The virtual environment must exist before running
- Redis must be available (installed or installable via apt-get/brew)
## Integration with CI/CD
This script can be integrated into CI/CD pipelines:
```yaml
# Example GitHub Actions
- name: Test Webhook Feature
run: |
chmod +x tests/test_webhook_feature.sh
./tests/test_webhook_feature.sh
```
## Support
If you encounter issues:
1. Check the troubleshooting section above
2. Review server logs at `/tmp/crawl4ai_server.log`
3. Ensure all prerequisites are met
4. Open an issue with the full output of the script
