# CDP Browser Concurrency Fixes and Improvements
## Overview
This document describes the changes made to fix concurrency issues with CDP (Chrome DevTools Protocol) browsers when using `arun_many` and improve overall browser management.
## Problems Addressed
1. **Race Conditions in Page Creation**: When using managed CDP browsers with concurrent `arun_many` calls, the code attempted to reuse existing pages from `context.pages`, leading to race conditions and "Target page/context closed" errors.
2. **Proxy Configuration Issues**: Proxy credentials were incorrectly embedded in the `--proxy-server` URL, which doesn't work properly with CDP browsers.
3. **Insufficient Startup Checks**: Browser process startup checks were minimal and didn't catch early failures effectively.
4. **Unclear Logging**: Logging messages lacked structure and context, making debugging difficult.
5. **Duplicate Browser Arguments**: Browser launch arguments could contain duplicates despite deduplication attempts.
## Solutions Implemented
### 1. Always Create New Pages in Managed Browser Mode
**File**: `crawl4ai/browser_manager.py` (lines 1106-1113)
**Change**: Modified `get_page()` method to always create new pages instead of attempting to reuse existing ones for managed browsers without `storage_state`.
**Before**:
```python
context = self.default_context
pages = context.pages
page = next((p for p in pages if p.url == crawlerRunConfig.url), None)
if not page:
if pages:
page = pages[0]
else:
# Create new page only if none exist
async with self._page_lock:
page = await context.new_page()
```
**After**:
```python
context = self.default_context
# Always create new pages instead of reusing existing ones
# This prevents race conditions in concurrent scenarios (arun_many with CDP)
# Serialize page creation to avoid 'Target page/context closed' errors
async with self._page_lock:
page = await context.new_page()
await self._apply_stealth_to_page(page)
```
**Benefits**:
- Eliminates race conditions when multiple tasks call `arun_many` concurrently
- Each request gets a fresh, independent page
- Page lock serializes creation to prevent TOCTOU (Time-of-check to time-of-use) issues
### 2. Fixed Proxy Flag Formatting
**File**: `crawl4ai/browser_manager.py` (lines 103-109)
**Change**: Removed credentials from proxy URL as they should be handled via separate authentication mechanisms in CDP.
**Before**:
```python
elif config.proxy_config:
creds = ""
if config.proxy_config.username and config.proxy_config.password:
creds = f"{config.proxy_config.username}:{config.proxy_config.password}@"
flags.append(f"--proxy-server={creds}{config.proxy_config.server}")
```
**After**:
```python
elif config.proxy_config:
# Note: For CDP/managed browsers, proxy credentials should be handled
# via authentication, not in the URL. Only pass the server address.
flags.append(f"--proxy-server={config.proxy_config.server}")
```
### 3. Enhanced Startup Checks
**File**: `crawl4ai/browser_manager.py` (lines 298-336)
**Changes**:
- Multiple check intervals (0.1s, 0.2s, 0.3s) to catch early failures
- Capture and log stdout/stderr on failure (limited to 200 chars)
- Raise `RuntimeError` with detailed diagnostics on startup failure
- Log process PID on successful startup in verbose mode
**Benefits**:
- Catches browser crashes during startup
- Provides detailed diagnostic information for debugging
- Fails fast with clear error messages
### 4. Improved Logging
**File**: `crawl4ai/browser_manager.py` (lines 218-291)
**Changes**:
- Structured logging with proper parameter substitution
- Log browser type, port, and headless status at launch
- Format and log full command with proper shell escaping
- Better error messages with context
- Consistent use of logger with null checks
**Example**:
```python
if self.logger and self.browser_config.verbose:
self.logger.debug(
"Launching browser: {browser_type} | Port: {port} | Headless: {headless}",
tag="BROWSER",
params={
"browser_type": self.browser_type,
"port": self.debugging_port,
"headless": self.headless
}
)
```
### 5. Deduplicate Browser Launch Arguments
**File**: `crawl4ai/browser_manager.py` (lines 424-425)
**Change**: Added explicit deduplication after merging all flags.
```python
# merge common launch flags
flags.extend(self.build_browser_flags(self.browser_config))
# Deduplicate flags - use dict.fromkeys to preserve order while removing duplicates
flags = list(dict.fromkeys(flags))
```
### 6. Import Refactoring
**Files**: `crawl4ai/browser_manager.py`, `crawl4ai/browser_profiler.py`, `tests/browser/test_cdp_concurrency.py`
**Changes**: Organized all imports according to PEP 8:
1. Standard library imports (alphabetized)
2. Third-party imports (alphabetized)
3. Local imports (alphabetized)
**Benefits**:
- Improved code readability
- Easier to spot missing or unused imports
- Consistent style across the codebase
## Testing
### New Test Suite
**File**: `tests/browser/test_cdp_concurrency.py`
Comprehensive test suite with 8 tests covering:
1. **Basic Concurrent arun_many**: Validates multiple URLs can be crawled concurrently
2. **Sequential arun_many Calls**: Ensures multiple sequential batches work correctly
3. **Stress Test**: Multiple concurrent `arun_many` calls to test page lock effectiveness
4. **Page Isolation**: Verifies pages are truly independent
5. **Different Configurations**: Tests with varying viewport sizes and configs
6. **Error Handling**: Ensures errors in one request don't affect others
7. **Large Batches**: Scalability test with 10+ URLs
8. **Smoke Test Script**: Standalone script for quick validation
### Running Tests
**With pytest** (if available):
```bash
cd /path/to/crawl4ai
pytest tests/browser/test_cdp_concurrency.py -v
```
**Standalone smoke test**:
```bash
cd /path/to/crawl4ai
python3 tests/browser/smoke_test_cdp.py
```
## Migration Guide
### For Users
No breaking changes. Existing code will continue to work, but with better reliability in concurrent scenarios.
### For Contributors
When working with managed browsers:
1. Always use the page lock when creating pages in shared contexts
2. Prefer creating new pages over reusing existing ones for concurrent operations
3. Use structured logging with parameter substitution
4. Follow PEP 8 import organization
## Performance Impact
- **Positive**: Eliminates race conditions and crashes in concurrent scenarios
- **Neutral**: Page creation overhead is negligible compared to page navigation
- **Consideration**: More pages may be created, but they are properly closed after use
## Backward Compatibility
All changes are backward compatible. Session-based page reuse still works as before when `session_id` is provided.
## Related Issues
- Fixes race conditions in concurrent `arun_many` calls with CDP browsers
- Addresses "Target page/context closed" errors
- Improves browser startup reliability
## Future Improvements
Consider:
1. Configurable page pooling with proper lifecycle management
2. More granular locks for different contexts
3. Metrics for page creation/reuse patterns
4. Connection pooling for CDP connections

# Crawl4AI Docker Memory & Pool Optimization - Implementation Log
## Critical Issues Identified
### Memory Management
- **Host vs Container**: `psutil.virtual_memory()` reported host memory, not container limits
- **Browser Pooling**: No pool reuse - every endpoint created new browsers
- **Warmup Waste**: Permanent browser sat idle with mismatched config signature
- **Idle Cleanup**: 30min TTL too long, janitor ran every 60s
- **Endpoint Inconsistency**: 75% of endpoints bypassed pool (`/md`, `/html`, `/screenshot`, `/pdf`, `/execute_js`, `/llm`)
### Pool Design Flaws
- **Config Mismatch**: Permanent browser used `config.yml` args, endpoints used empty `BrowserConfig()`
- **Logging Level**: Pool hit markers at DEBUG, invisible with INFO logging
## Implementation Changes
### 1. Container-Aware Memory Detection (`utils.py`)
```python
def get_container_memory_percent() -> float:
# Try cgroup v2 → v1 → fallback to psutil
# Reads /sys/fs/cgroup/memory.{current,max} OR memory/memory.{usage,limit}_in_bytes
```
### 2. Smart Browser Pool (`crawler_pool.py`)
**3-Tier System:**
- **PERMANENT**: Always-ready default browser (never cleaned)
- **HOT_POOL**: Configs used 3+ times (longer TTL)
- **COLD_POOL**: New/rare configs (short TTL)
**Key Functions:**
- `get_crawler(cfg)`: Check permanent → hot → cold → create new
- `init_permanent(cfg)`: Initialize permanent at startup
- `janitor()`: Adaptive cleanup (10s/30s/60s intervals based on memory)
- `_sig(cfg)`: SHA1 hash of config dict for pool keys
**Logging Fix**: Changed `logger.debug()``logger.info()` for pool hits
### 3. Endpoint Unification
**Helper Function** (`server.py`):
```python
def get_default_browser_config() -> BrowserConfig:
return BrowserConfig(
extra_args=config["crawler"]["browser"].get("extra_args", []),
**config["crawler"]["browser"].get("kwargs", {}),
)
```
**Migrated Endpoints:**
- `/html`, `/screenshot`, `/pdf`, `/execute_js` → use `get_default_browser_config()`
- `handle_llm_qa()`, `handle_markdown_request()` → same
**Result**: All endpoints now hit permanent browser pool
### 4. Config Updates (`config.yml`)
- `idle_ttl_sec: 1800``300` (30min → 5min base TTL)
- `port: 11234``11235` (fixed mismatch with Gunicorn)
### 5. Lifespan Fix (`server.py`)
```python
await init_permanent(BrowserConfig(
extra_args=config["crawler"]["browser"].get("extra_args", []),
**config["crawler"]["browser"].get("kwargs", {}),
))
```
Permanent browser now matches endpoint config signatures
## Test Results
### Test 1: Basic Health
- 10 requests to `/health`
- **Result**: 100% success, avg 3ms latency
- **Baseline**: Container starts in ~5s, 270 MB idle
### Test 2: Memory Monitoring
- 20 requests with Docker stats tracking
- **Result**: 100% success, no memory leak (-0.2 MB delta)
- **Baseline**: 269.7 MB container overhead
### Test 3: Pool Validation
- 30 requests to `/html` endpoint
- **Result**: **100% permanent browser hits**, 0 new browsers created
- **Memory**: 287 MB baseline → 396 MB active (+109 MB)
- **Latency**: Avg 4s (includes network to httpbin.org)
### Test 4: Concurrent Load
- Light (10) → Medium (50) → Heavy (100) concurrent
- **Total**: 320 requests
- **Result**: 100% success, **320/320 permanent hits**, 0 new browsers
- **Memory**: 269 MB → peak 1533 MB → final 993 MB
- **Latency**: P99 at 100 concurrent = 34s (expected with single browser)
### Test 5: Pool Stress (Mixed Configs)
- 20 requests with 4 different viewport configs
- **Result**: 4 new browsers, 4 cold hits, **4 promotions to hot**, 8 hot hits
- **Reuse Rate**: 60% (12 pool hits / 20 requests)
- **Memory**: 270 MB → 928 MB peak (+658 MB = ~165 MB per browser)
- **Proves**: Cold → hot promotion at 3 uses working perfectly
### Test 6: Multi-Endpoint
- 10 requests each: `/html`, `/screenshot`, `/pdf`, `/crawl`
- **Result**: 100% success across all 4 endpoints
- **Latency**: 5-8s avg (PDF slowest at 7.2s)
### Test 7: Cleanup Verification
- 20 requests (load spike) → 90s idle
- **Memory**: 269 MB → peak 1107 MB → final 780 MB
- **Recovery**: 327 MB (39%) - partial cleanup
- **Note**: Hot pool browsers persist (by design), janitor working correctly
## Performance Metrics
| Metric | Before | After | Improvement |
|--------|--------|-------|-------------|
| Pool Reuse | 0% | 100% (default config) | ∞ |
| Memory Leak | Unknown | 0 MB/cycle | Stable |
| Browser Reuse | No | Yes | ~3-5s saved per request |
| Idle Memory | 500-700 MB × N | 270-400 MB | 10x reduction |
| Concurrent Capacity | ~20 | 100+ | 5x |
## Key Learnings
1. **Config Signature Matching**: Permanent browser MUST match endpoint default config exactly (SHA1 hash)
2. **Logging Levels**: Pool diagnostics need INFO level, not DEBUG
3. **Memory in Docker**: Must read cgroup files, not host metrics
4. **Janitor Timing**: 60s interval adequate, but TTLs should be short (5min) for cold pool
5. **Hot Promotion**: 3-use threshold works well for production patterns
6. **Memory Per Browser**: ~150-200 MB per Chromium instance with headless + text_mode
## Test Infrastructure
**Location**: `deploy/docker/tests/`
**Dependencies**: `httpx`, `docker` (Python SDK)
**Pattern**: Sequential build - each test adds one capability
**Files**:
- `test_1_basic.py`: Health check + container lifecycle
- `test_2_memory.py`: + Docker stats monitoring
- `test_3_pool.py`: + Log analysis for pool markers
- `test_4_concurrent.py`: + asyncio.Semaphore for concurrency control
- `test_5_pool_stress.py`: + Config variants (viewports)
- `test_6_multi_endpoint.py`: + Multiple endpoint testing
- `test_7_cleanup.py`: + Time-series memory tracking for janitor
**Run Pattern**:
```bash
cd deploy/docker/tests
pip install -r requirements.txt
# Rebuild after code changes:
cd /path/to/repo && docker buildx build -t crawl4ai-local:latest --load .
# Run test:
python test_N_name.py
```
## Architecture Decisions
**Why Permanent Browser?**
- 90% of requests use default config → single browser serves most traffic
- Eliminates 3-5s startup overhead per request
**Why 3-Tier Pool?**
- Permanent: Zero cost for common case
- Hot: Amortized cost for frequent variants
- Cold: Lazy allocation for rare configs
**Why Adaptive Janitor?**
- Memory pressure triggers aggressive cleanup
- Low memory allows longer TTLs for better reuse
**Why Not Close After Each Request?**
- Browser startup: 3-5s overhead
- Pool reuse: <100ms overhead
- Net: 30-50x faster
## Future Optimizations
1. **Request Queuing**: When at capacity, queue instead of reject
2. **Pre-warming**: Predict common configs, pre-create browsers
3. **Metrics Export**: Prometheus metrics for pool efficiency
4. **Config Normalization**: Group similar viewports (e.g., 1920±50 → 1920)
## Critical Code Paths
**Browser Acquisition** (`crawler_pool.py:34-78`):
```
get_crawler(cfg) →
_sig(cfg) →
if sig == DEFAULT_CONFIG_SIG → PERMANENT
elif sig in HOT_POOL → HOT_POOL[sig]
elif sig in COLD_POOL → promote if count >= 3
else → create new in COLD_POOL
```
**Janitor Loop** (`crawler_pool.py:107-146`):
```
while True:
mem% = get_container_memory_percent()
if mem% > 80: interval=10s, cold_ttl=30s
elif mem% > 60: interval=30s, cold_ttl=60s
else: interval=60s, cold_ttl=300s
sleep(interval)
close idle browsers (COLD then HOT)
```
**Endpoint Pattern** (`server.py` example):
```python
@app.post("/html")
async def generate_html(...):
from crawler_pool import get_crawler
crawler = await get_crawler(get_default_browser_config())
results = await crawler.arun(url=body.url, config=cfg)
# No crawler.close() - returned to pool
```
## Debugging Tips
**Check Pool Activity**:
```bash
docker logs crawl4ai-test | grep -E "(🔥|♨️|❄️|🆕|⬆️)"
```
**Verify Config Signature**:
```python
from crawl4ai import BrowserConfig
import json, hashlib
cfg = BrowserConfig(...)
sig = hashlib.sha1(json.dumps(cfg.to_dict(), sort_keys=True).encode()).hexdigest()
print(sig[:8]) # Compare with logs
```
**Monitor Memory**:
```bash
docker stats crawl4ai-test
```
## Known Limitations
- **Mac Docker Stats**: CPU metrics unreliable, memory works
- **PDF Generation**: Slowest endpoint (~7s), no optimization yet
- **Hot Pool Persistence**: May hold memory longer than needed (trade-off for performance)
- **Janitor Lag**: Up to 60s before cleanup triggers in low-memory scenarios

# 🚀 Crawl4AI v0.7.7: The Self-Hosting & Monitoring Update
*November 14, 2025 • 10 min read*
---
Today I'm releasing Crawl4AI v0.7.7—the Self-Hosting & Monitoring Update. This release transforms Crawl4AI Docker from a simple containerized crawler into a complete self-hosting platform with enterprise-grade real-time monitoring, full operational transparency, and production-ready observability.
## 🎯 What's New at a Glance
- **📊 Real-time Monitoring Dashboard**: Interactive web UI with live system metrics and browser pool status
- **🔌 Comprehensive Monitor API**: Complete REST API for programmatic access to all monitoring data
- **⚡ WebSocket Streaming**: Real-time updates every 2 seconds for custom dashboards
- **🎮 Control Actions**: Manual browser management (kill, restart, cleanup)
- **🔥 Smart Browser Pool**: 3-tier architecture (permanent/hot/cold) with automatic promotion
- **🧹 Janitor Cleanup System**: Automatic resource management with event logging
- **📈 Production Metrics**: 6 critical metrics for operational excellence
- **🏭 Integration Ready**: Prometheus, alerting, and log aggregation examples
- **🐛 Critical Bug Fixes**: Async LLM extraction, DFS crawling, viewport config, and more
## 📊 Real-time Monitoring Dashboard: Complete Visibility
**The Problem:** Running Crawl4AI in Docker was like flying blind. Users had no visibility into what was happening inside the container—memory usage, active requests, browser pools, or errors. Troubleshooting required checking logs, and there was no way to monitor performance or manually intervene when issues occurred.
**My Solution:** I built a complete real-time monitoring system with an interactive dashboard, comprehensive REST API, WebSocket streaming, and manual control actions. Now you have full transparency and control over your crawling infrastructure.
### The Self-Hosting Value Proposition
Before v0.7.7, Docker was just a containerized crawler. After v0.7.7, it's a complete self-hosting platform that gives you:
- **🔒 Data Privacy**: Your data never leaves your infrastructure
- **💰 Cost Control**: No per-request pricing or rate limits
- **🎯 Full Customization**: Complete control over configurations and strategies
- **📊 Complete Transparency**: Real-time visibility into every aspect
- **⚡ Performance**: Direct access without network overhead
- **🛡️ Enterprise Security**: Keep workflows behind your firewall
### Interactive Monitoring Dashboard
Access the dashboard at `http://localhost:11235/dashboard` to see:
- **System Health Overview**: CPU, memory, network, and uptime in real-time
- **Live Request Tracking**: Active and completed requests with full details
- **Browser Pool Management**: Interactive table with permanent/hot/cold browsers
- **Janitor Events Log**: Automatic cleanup activities
- **Error Monitoring**: Full context error logs
The dashboard updates every 2 seconds via WebSocket, giving you live visibility into your crawling operations.
## 🔌 Monitor API: Programmatic Access
**The Problem:** Monitoring dashboards are great for humans, but automation and integration require programmatic access.
**My Solution:** A comprehensive REST API that exposes all monitoring data for integration with your existing infrastructure.
### System Health Endpoint
```python
import httpx
import asyncio
async def monitor_system_health():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/health")
health = response.json()
print(f"Container Metrics:")
print(f" CPU: {health['container']['cpu_percent']:.1f}%")
print(f" Memory: {health['container']['memory_percent']:.1f}%")
print(f" Uptime: {health['container']['uptime_seconds']}s")
print(f"\nBrowser Pool:")
print(f" Permanent: {health['pool']['permanent']['active']} active")
print(f" Hot Pool: {health['pool']['hot']['count']} browsers")
print(f" Cold Pool: {health['pool']['cold']['count']} browsers")
print(f"\nStatistics:")
print(f" Total Requests: {health['stats']['total_requests']}")
print(f" Success Rate: {health['stats']['success_rate_percent']:.1f}%")
print(f" Avg Latency: {health['stats']['avg_latency_ms']:.0f}ms")
asyncio.run(monitor_system_health())
```
### Request Tracking
```python
async def track_requests():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/requests")
requests_data = response.json()
print(f"Active Requests: {len(requests_data['active'])}")
print(f"Completed Requests: {len(requests_data['completed'])}")
# See details of recent requests
for req in requests_data['completed'][:5]:
status_icon = "" if req['success'] else ""
print(f"{status_icon} {req['endpoint']} - {req['latency_ms']:.0f}ms")
```
### Browser Pool Management
```python
async def monitor_browser_pool():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/browsers")
browsers = response.json()
print(f"Pool Summary:")
print(f" Total Browsers: {browsers['summary']['total_count']}")
print(f" Total Memory: {browsers['summary']['total_memory_mb']} MB")
print(f" Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
# List all browsers
for browser in browsers['permanent']:
print(f"🔥 Permanent: {browser['browser_id'][:8]}... | "
f"Requests: {browser['request_count']} | "
f"Memory: {browser['memory_mb']:.0f} MB")
```
### Endpoint Performance Statistics
```python
async def get_endpoint_stats():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/endpoints/stats")
stats = response.json()
print("Endpoint Analytics:")
for endpoint, data in stats.items():
print(f" {endpoint}:")
print(f" Requests: {data['count']}")
print(f" Avg Latency: {data['avg_latency_ms']:.0f}ms")
print(f" Success Rate: {data['success_rate_percent']:.1f}%")
```
### Complete API Reference
The Monitor API includes these endpoints:
- `GET /monitor/health` - System health with pool statistics
- `GET /monitor/requests` - Active and completed request tracking
- `GET /monitor/browsers` - Browser pool details and efficiency
- `GET /monitor/endpoints/stats` - Per-endpoint performance analytics
- `GET /monitor/timeline?minutes=5` - Time-series data for charts
- `GET /monitor/logs/janitor?limit=10` - Cleanup activity logs
- `GET /monitor/logs/errors?limit=10` - Error logs with context
- `POST /monitor/actions/cleanup` - Force immediate cleanup
- `POST /monitor/actions/kill_browser` - Kill specific browser
- `POST /monitor/actions/restart_browser` - Restart browser
- `POST /monitor/stats/reset` - Reset accumulated statistics
## ⚡ WebSocket Streaming: Real-time Updates
**The Problem:** Polling the API every few seconds wastes resources and adds latency. Real-time dashboards need instant updates.
**My Solution:** WebSocket streaming with 2-second update intervals for building custom real-time dashboards.
### WebSocket Integration Example
```python
import websockets
import json
import asyncio
async def monitor_realtime():
uri = "ws://localhost:11235/monitor/ws"
async with websockets.connect(uri) as websocket:
print("Connected to real-time monitoring stream")
while True:
# Receive update every 2 seconds
data = await websocket.recv()
update = json.loads(data)
# Access all monitoring data
print(f"\n--- Update at {update['timestamp']} ---")
print(f"Memory: {update['health']['container']['memory_percent']:.1f}%")
print(f"Active Requests: {len(update['requests']['active'])}")
print(f"Total Browsers: {update['browsers']['summary']['total_count']}")
if update['errors']:
print(f"⚠️ Recent Errors: {len(update['errors'])}")
asyncio.run(monitor_realtime())
```
**Expected Real-World Impact:**
- **Custom Dashboards**: Build tailored monitoring UIs for your team
- **Real-time Alerting**: Trigger alerts instantly when metrics exceed thresholds
- **Integration**: Feed live data into monitoring tools like Grafana
- **Automation**: React to events in real-time without polling
## 🔥 Smart Browser Pool: 3-Tier Architecture
**The Problem:** Creating a new browser for every request is slow and memory-intensive. Traditional browser pools are static and inefficient.
**My Solution:** A smart 3-tier browser pool that automatically adapts to usage patterns.
### How It Works
```python
import httpx
async def demonstrate_browser_pool():
async with httpx.AsyncClient() as client:
# Request 1-3: Default config → Uses permanent browser
print("Phase 1: Using permanent browser")
for i in range(3):
await client.post(
"http://localhost:11235/crawl",
json={"urls": [f"https://httpbin.org/html?req={i}"]}
)
print(f" Request {i+1}: Reused permanent browser")
# Request 4-6: Custom viewport → Cold pool (first use)
print("\nPhase 2: Custom config creates cold pool browser")
viewport_config = {"viewport": {"width": 1280, "height": 720}}
for i in range(4):
await client.post(
"http://localhost:11235/crawl",
json={
"urls": [f"https://httpbin.org/json?v={i}"],
"browser_config": viewport_config
}
)
if i < 2:
print(f" Request {i+1}: Cold pool browser")
else:
print(f" Request {i+1}: Promoted to hot pool! (after 3 uses)")
# Check pool status
response = await client.get("http://localhost:11235/monitor/browsers")
browsers = response.json()
print(f"\nPool Status:")
print(f" Permanent: {len(browsers['permanent'])} (always active)")
print(f" Hot: {len(browsers['hot'])} (frequently used configs)")
print(f" Cold: {len(browsers['cold'])} (on-demand)")
print(f" Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
asyncio.run(demonstrate_browser_pool())
```
**Pool Tiers:**
- **🔥 Permanent Browser**: Always-on, default configuration, instant response
- **♨️ Hot Pool**: Browsers promoted after 3+ uses, kept warm for quick access
- **❄️ Cold Pool**: On-demand browsers for variant configs, cleaned up when idle
**Expected Real-World Impact:**
- **Memory Efficiency**: 10x reduction in memory usage vs creating browsers per request
- **Performance**: Instant access to frequently-used configurations
- **Automatic Optimization**: Pool adapts to your usage patterns
- **Resource Management**: Janitor automatically cleans up idle browsers
## 🧹 Janitor System: Automatic Cleanup
**The Problem:** Long-running crawlers accumulate idle browsers and consume memory over time.
**My Solution:** An automatic janitor system that monitors and cleans up idle resources.
```python
async def monitor_janitor_activity():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/logs/janitor?limit=5")
logs = response.json()
print("Recent Cleanup Activities:")
for log in logs:
print(f" {log['timestamp']}: {log['message']}")
# Example output:
# 2025-11-14 10:30:00: Cleaned up 2 cold pool browsers (idle > 5min)
# 2025-11-14 10:25:00: Browser reuse rate: 85.3%
# 2025-11-14 10:20:00: Hot pool browser promoted (10 requests)
```
## 🎮 Control Actions: Manual Management
**The Problem:** Sometimes you need to manually intervene—kill a stuck browser, force cleanup, or restart resources.
**My Solution:** Manual control actions via the API for operational troubleshooting.
### Force Cleanup
```python
async def force_cleanup():
async with httpx.AsyncClient() as client:
response = await client.post("http://localhost:11235/monitor/actions/cleanup")
result = response.json()
print(f"Cleanup completed:")
print(f" Browsers cleaned: {result.get('cleaned_count', 0)}")
print(f" Memory freed: {result.get('memory_freed_mb', 0):.1f} MB")
```
### Kill Specific Browser
```python
async def kill_stuck_browser(browser_id: str):
async with httpx.AsyncClient() as client:
response = await client.post(
"http://localhost:11235/monitor/actions/kill_browser",
json={"browser_id": browser_id}
)
if response.status_code == 200:
print(f"✅ Browser {browser_id} killed successfully")
```
### Reset Statistics
```python
async def reset_stats():
async with httpx.AsyncClient() as client:
response = await client.post("http://localhost:11235/monitor/stats/reset")
print("📊 Statistics reset for fresh monitoring")
```
## 📈 Production Integration Patterns
### Prometheus Integration
```python
# Export metrics for Prometheus scraping
async def export_prometheus_metrics():
async with httpx.AsyncClient() as client:
health = await client.get("http://localhost:11235/monitor/health")
data = health.json()
# Export in Prometheus format
metrics = f"""
# HELP crawl4ai_memory_usage_percent Memory usage percentage
# TYPE crawl4ai_memory_usage_percent gauge
crawl4ai_memory_usage_percent {data['container']['memory_percent']}
# HELP crawl4ai_request_success_rate Request success rate
# TYPE crawl4ai_request_success_rate gauge
crawl4ai_request_success_rate {data['stats']['success_rate_percent']}
# HELP crawl4ai_browser_pool_count Total browsers in pool
# TYPE crawl4ai_browser_pool_count gauge
crawl4ai_browser_pool_count {data['pool']['permanent']['active'] + data['pool']['hot']['count'] + data['pool']['cold']['count']}
"""
return metrics
```
### Alerting Example
```python
async def check_alerts():
async with httpx.AsyncClient() as client:
health = await client.get("http://localhost:11235/monitor/health")
data = health.json()
# Memory alert
if data['container']['memory_percent'] > 80:
print("🚨 ALERT: Memory usage above 80%")
# Trigger cleanup
await client.post("http://localhost:11235/monitor/actions/cleanup")
# Success rate alert
if data['stats']['success_rate_percent'] < 90:
print("🚨 ALERT: Success rate below 90%")
# Check error logs
errors = await client.get("http://localhost:11235/monitor/logs/errors")
print(f"Recent errors: {len(errors.json())}")
# Latency alert
if data['stats']['avg_latency_ms'] > 5000:
print("🚨 ALERT: Average latency above 5s")
```
### Key Metrics to Track
```python
CRITICAL_METRICS = {
"memory_usage": {
"current": "container.memory_percent",
"target": "<80%",
"alert_threshold": ">80%",
"action": "Force cleanup or scale"
},
"success_rate": {
"current": "stats.success_rate_percent",
"target": ">95%",
"alert_threshold": "<90%",
"action": "Check error logs"
},
"avg_latency": {
"current": "stats.avg_latency_ms",
"target": "<2000ms",
"alert_threshold": ">5000ms",
"action": "Investigate slow requests"
},
"browser_reuse_rate": {
"current": "browsers.summary.reuse_rate_percent",
"target": ">80%",
"alert_threshold": "<60%",
"action": "Check pool configuration"
},
"total_browsers": {
"current": "browsers.summary.total_count",
"target": "<15",
"alert_threshold": ">20",
"action": "Check for browser leaks"
},
"error_frequency": {
"current": "len(errors)",
"target": "<5/hour",
"alert_threshold": ">10/hour",
"action": "Review error patterns"
}
}
```
## 🐛 Critical Bug Fixes
This release includes significant bug fixes that improve stability and performance:
### Async LLM Extraction (#1590)
**The Problem:** LLM extraction was blocking async execution, causing URLs to be processed sequentially instead of in parallel (issue #1055).
**The Fix:** Resolved the blocking issue to enable true parallel processing for LLM extraction.
```python
# Before v0.7.7: Sequential processing
# After v0.7.7: True parallel processing
async with AsyncWebCrawler() as crawler:
urls = ["url1", "url2", "url3", "url4"]
# Now processes truly in parallel with LLM extraction
results = await crawler.arun_many(
urls,
config=CrawlerRunConfig(
extraction_strategy=LLMExtractionStrategy(...)
)
)
# 4x faster for parallel LLM extraction!
```
**Expected Impact:** Major performance improvement for batch LLM extraction workflows.
### DFS Deep Crawling (#1607)
**The Problem:** DFS (Depth-First Search) deep crawl strategy had implementation issues.
**The Fix:** Enhanced DFSDeepCrawlStrategy with proper seen URL tracking and improved documentation.
### Browser & Crawler Config Documentation (#1609)
**The Problem:** Documentation didn't match the actual `async_configs.py` implementation.
**The Fix:** Updated all configuration documentation to accurately reflect the current implementation.
### Sitemap Seeder (#1598)
**The Problem:** Sitemap parsing and URL normalization issues in AsyncUrlSeeder (issue #1559).
**The Fix:** Added comprehensive tests and fixes for sitemap namespace parsing and URL normalization.
### Remove Overlay Elements (#1529)
**The Problem:** The `remove_overlay_elements` functionality wasn't working (issue #1396).
**The Fix:** Fixed by properly calling the injected JavaScript function.
### Viewport Configuration (#1495)
**The Problem:** Viewport configuration wasn't working in managed browsers (issue #1490).
**The Fix:** Added proper viewport size configuration support for browser launch.
### Managed Browser CDP Timing (#1528)
**The Problem:** CDP (Chrome DevTools Protocol) endpoint verification had timing issues causing connection failures (issue #1445).
**The Fix:** Added exponential backoff for CDP endpoint verification to handle timing variations.
### Security Updates
- **pyOpenSSL**: Updated from >=24.3.0 to >=25.3.0 to address security vulnerability
- Added verification tests for the security update
### Docker Fixes
- **Port Standardization**: Fixed inconsistent port usage (11234 vs 11235) - now standardized to 11235
- **LLM Environment**: Fixed LLM API key handling for multi-provider support (PR #1537)
- **Error Handling**: Improved Docker API error messages with comprehensive status codes
- **Serialization**: Fixed `fit_html` property serialization in `/crawl` and `/crawl/stream` endpoints
### Other Important Fixes
- **arun_many Returns**: Fixed function to always return a list, even on exception (PR #1530)
- **Webhook Serialization**: Properly serialize Pydantic HttpUrl in webhook config
- **LLMConfig Documentation**: Fixed casing and variable name consistency (issue #1551)

### Docker & API Fixes
#### ContentRelevanceFilter Deserialization (#1642)
**The Problem:** When sending deep crawl requests to the Docker API with `ContentRelevanceFilter`, the server failed to deserialize the filter, causing requests to fail.
**The Fix:** I added `ContentRelevanceFilter` to the public exports and enhanced the deserialization logic with dynamic imports.
```python
# This now works correctly in Docker API
import httpx
request = {
"urls": ["https://docs.example.com"],
"crawler_config": {
"deep_crawl_strategy": {
"type": "BFSDeepCrawlStrategy",
"max_depth": 2,
"filter_chain": [
{
"type": "ContentRelevanceFilter",
"query": "API documentation",
"threshold": 0.3
}
]
}
}
}
async with httpx.AsyncClient() as client:
response = await client.post("http://localhost:11235/crawl", json=request)
# Previously failed, now works!
```
#### ProxyConfig JSON Serialization (#1629)
**The Problem:** `BrowserConfig.to_dict()` failed when `proxy_config` was set because `ProxyConfig` wasn't being serialized to a dictionary.
**The Fix:** `ProxyConfig.to_dict()` is now called during serialization.
```python
from crawl4ai import BrowserConfig
from crawl4ai.async_configs import ProxyConfig
proxy = ProxyConfig(
server="http://proxy.example.com:8080",
username="user",
password="pass"
)
config = BrowserConfig(headless=True, proxy_config=proxy)
# Previously raised TypeError, now works
config_dict = config.to_dict()
json.dumps(config_dict) # Valid JSON
```
#### Docker Cache Folder Permissions (#1638)
**The Problem:** The `.cache` folder in the Docker image had incorrect permissions, causing crawling to fail when caching was enabled.
**The Fix:** Corrected ownership and permissions during image build.
```bash
# Cache now works correctly in Docker
docker run -d -p 11235:11235 \
--shm-size=1g \
-v ./my-cache:/app/.cache \
unclecode/crawl4ai:0.7.8
```
---
### LLM & Extraction Fixes
#### Configurable Rate Limiter Backoff (#1269)
**The Problem:** The LLM rate limiting backoff parameters were hardcoded, making it impossible to adjust retry behavior for different API rate limits.
**The Fix:** `LLMConfig` now accepts three new parameters for complete control over retry behavior.
```python
from crawl4ai import LLMConfig
# Default behavior (unchanged)
default_config = LLMConfig(provider="openai/gpt-4o-mini")
# backoff_base_delay=2, backoff_max_attempts=3, backoff_exponential_factor=2
# Custom configuration for APIs with strict rate limits
custom_config = LLMConfig(
provider="openai/gpt-4o-mini",
backoff_base_delay=5, # Wait 5 seconds on first retry
backoff_max_attempts=5, # Try up to 5 times
backoff_exponential_factor=3 # Multiply delay by 3 each attempt
)
# Retry sequence: 5s -> 15s -> 45s -> 135s -> 405s
```
#### LLM Strategy HTML Input Support (#1178)
**The Problem:** `LLMExtractionStrategy` always sent markdown to the LLM, but some extraction tasks work better with HTML structure preserved.
**The Fix:** Added `input_format` parameter supporting `"markdown"`, `"html"`, `"fit_markdown"`, `"cleaned_html"`, and `"fit_html"`.
```python
from crawl4ai import LLMExtractionStrategy, LLMConfig
# Default: markdown input (unchanged)
markdown_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini"),
instruction="Extract product information"
)
# NEW: HTML input - preserves table/list structure
html_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini"),
instruction="Extract the data table preserving structure",
input_format="html"
)
# NEW: Filtered markdown - only relevant content
fit_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini"),
instruction="Summarize the main content",
input_format="fit_markdown"
)
```
#### Raw HTML URL Variable (#1116)
**The Problem:** When using `url="raw:<html>..."`, the entire HTML content was being passed to extraction strategies as the URL parameter, polluting LLM prompts.
**The Fix:** The URL is now correctly set to `"Raw HTML"` for raw HTML inputs.
```python
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
html = "<html><body><h1>Test</h1></body></html>"
async with AsyncWebCrawler() as crawler:
result = await crawler.arun(
url=f"raw:{html}",
config=CrawlerRunConfig(extraction_strategy=my_strategy)
)
# extraction_strategy receives url="Raw HTML" instead of the HTML blob
```
---
### URL Handling Fix
#### Relative URLs After Redirects (#1268)
**The Problem:** When JavaScript caused a page redirect, relative links were resolved against the original URL instead of the final URL.
**The Fix:** `redirected_url` now captures the actual page URL after all JavaScript execution completes.
```python
from crawl4ai import AsyncWebCrawler
async with AsyncWebCrawler() as crawler:
# Page at /old-page redirects via JS to /new-page
result = await crawler.arun(url="https://example.com/old-page")
# BEFORE: redirected_url = "https://example.com/old-page"
# AFTER: redirected_url = "https://example.com/new-page"
# Links are now correctly resolved against the final URL
for link in result.links['internal']:
print(link['href']) # Relative links resolved correctly
```
---
### Dependency & Compatibility Fixes
#### PyPDF2 Replaced with pypdf (#1412)
**The Problem:** PyPDF2 was deprecated in 2022 and is no longer maintained.
**The Fix:** Replaced with the actively maintained `pypdf` library.
```python
# Installation (unchanged)
pip install crawl4ai[pdf]
# The PDF processor now uses pypdf internally
# No code changes required - API remains the same
```
#### Pydantic v2 ConfigDict Compatibility (#678)
**The Problem:** Using the deprecated `class Config` syntax caused deprecation warnings with Pydantic v2.
**The Fix:** Migrated to `model_config = ConfigDict(...)` syntax.
```python
# No more deprecation warnings when importing crawl4ai models
from crawl4ai.models import CrawlResult
from crawl4ai import CrawlerRunConfig, BrowserConfig
# All models are now Pydantic v2 compatible
```
---
### AdaptiveCrawler Fix
#### Query Expansion Using LLM (#1621)
**The Problem:** The `EmbeddingStrategy` in AdaptiveCrawler had commented-out LLM code and was using hardcoded mock query variations instead.
**The Fix:** Uncommented and activated the LLM call for actual query expansion.
```python
# AdaptiveCrawler query expansion now actually uses the LLM
# Instead of hardcoded variations like:
# variations = {'queries': ['what are the best vegetables...']}
# The LLM generates relevant query variations based on your actual query
```
---
### Code Formatting Fix
#### Import Statement Formatting (#1181)
**The Problem:** When extracting code from web pages, import statements were sometimes concatenated without proper line separation.
**The Fix:** Import statements now maintain proper newline separation.
```python
# BEFORE: "import osimport sysfrom pathlib import Path"
# AFTER:
# import os
# import sys
# from pathlib import Path
```
---
## Breaking Changes
**None!** This release is fully backward compatible.
- All existing code continues to work without modification
- New parameters have sensible defaults matching previous behavior
- No API changes to existing functionality
---
## Upgrade Instructions
### Python Package
```bash
pip install --upgrade crawl4ai
# or
pip install crawl4ai==0.7.8
```
### Docker
```bash
# Pull the latest version
docker pull unclecode/crawl4ai:0.7.8
# Run
docker run -d -p 11235:11235 --shm-size=1g unclecode/crawl4ai:0.7.8
```
---
## Verification
Run the verification tests to confirm all fixes are working:
```bash
python docs/releases_review/demo_v0.7.8.py
```
This runs actual tests that verify each bug fix is properly implemented.

# Proxy & Security
This guide covers proxy configuration and security features in Crawl4AI, including SSL certificate analysis and proxy rotation strategies.
## Understanding Proxy Configuration
Crawl4AI recommends configuring proxies per request through `CrawlerRunConfig.proxy_config`. This gives you precise control, enables rotation strategies, and keeps examples simple enough to copy, paste, and run.
# Proxy
## Basic Proxy Setup
Configure proxies that apply to each crawl operation:
Simple proxy configuration with `BrowserConfig`:
```python
import asyncio
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, ProxyConfig
from crawl4ai.async_configs import BrowserConfig
run_config = CrawlerRunConfig(proxy_config=ProxyConfig(server="http://proxy.example.com:8080"))
# run_config = CrawlerRunConfig(proxy_config={"server": "http://proxy.example.com:8080"})
# run_config = CrawlerRunConfig(proxy_config="http://proxy.example.com:8080")
# Using HTTP proxy
browser_config = BrowserConfig(proxy_config={"server": "http://proxy.example.com:8080"})
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com")
async def main():
browser_config = BrowserConfig()
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com", config=run_config)
print(f"Success: {result.success} -> {result.url}")
if __name__ == "__main__":
asyncio.run(main())
# Using SOCKS proxy
browser_config = BrowserConfig(proxy_config={"server": "socks5://proxy.example.com:1080"})
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com")
```
!!! note "Why request-level?"
`CrawlerRunConfig.proxy_config` keeps each request self-contained, so swapping proxies or rotation strategies is just a matter of building a new run configuration.
## Authenticated Proxy
## Supported Proxy Formats
The `ProxyConfig.from_string()` method supports multiple formats:
Use an authenticated proxy with `BrowserConfig`:
```python
from crawl4ai import ProxyConfig
from crawl4ai.async_configs import BrowserConfig
# HTTP proxy with authentication
proxy1 = ProxyConfig.from_string("http://user:pass@192.168.1.1:8080")
# HTTPS proxy
proxy2 = ProxyConfig.from_string("https://proxy.example.com:8080")
# SOCKS5 proxy
proxy3 = ProxyConfig.from_string("socks5://proxy.example.com:1080")
# Simple IP:port format
proxy4 = ProxyConfig.from_string("192.168.1.1:8080")
# IP:port:user:pass format
proxy5 = ProxyConfig.from_string("192.168.1.1:8080:user:pass")
browser_config = BrowserConfig(proxy_config={
"server": "http://[host]:[port]",
"username": "[username]",
"password": "[password]",
})
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com")
```
## Authenticated Proxies
For proxies requiring authentication:
## Rotating Proxies
Example using a proxy rotation service dynamically:
```python
import asyncio
from crawl4ai import AsyncWebCrawler,BrowserConfig, CrawlerRunConfig, ProxyConfig
run_config = CrawlerRunConfig(
proxy_config=ProxyConfig(
server="http://proxy.example.com:8080",
username="your_username",
password="your_password",
)
)
# Or dictionary style:
# run_config = CrawlerRunConfig(proxy_config={
# "server": "http://proxy.example.com:8080",
# "username": "your_username",
# "password": "your_password",
# })
async def main():
browser_config = BrowserConfig()
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com", config=run_config)
print(f"Success: {result.success} -> {result.url}")
if __name__ == "__main__":
asyncio.run(main())
```
## Environment Variable Configuration
Load proxies from environment variables for easy configuration:
```python
import os
from crawl4ai import ProxyConfig, CrawlerRunConfig
# Set environment variable
os.environ["PROXIES"] = "ip1:port1:user1:pass1,ip2:port2:user2:pass2,ip3:port3"
# Load all proxies
proxies = ProxyConfig.from_env()
print(f"Loaded {len(proxies)} proxies")
# Use first proxy
if proxies:
run_config = CrawlerRunConfig(proxy_config=proxies[0])
```
## Rotating Proxies
Crawl4AI supports automatic proxy rotation to distribute requests across multiple proxy servers. Rotation is applied per request using a rotation strategy on `CrawlerRunConfig`.
### Proxy Rotation (recommended)
```python
import asyncio
import re
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, CacheMode, ProxyConfig
from crawl4ai.proxy_strategy import RoundRobinProxyStrategy
from crawl4ai import (
AsyncWebCrawler,
BrowserConfig,
CrawlerRunConfig,
CacheMode,
RoundRobinProxyStrategy,
)
import asyncio
from crawl4ai import ProxyConfig
async def main():
# Load proxies from environment
# Load proxies and create rotation strategy
proxies = ProxyConfig.from_env()
#eg: export PROXIES="ip1:port1:username1:password1,ip2:port2:username2:password2"
if not proxies:
print("No proxies found! Set PROXIES environment variable.")
print("No proxies found in environment. Set PROXIES env variable!")
return
# Create rotation strategy
proxy_strategy = RoundRobinProxyStrategy(proxies)
# Configure per-request with proxy rotation
# Create configs
browser_config = BrowserConfig(headless=True, verbose=False)
run_config = CrawlerRunConfig(
cache_mode=CacheMode.BYPASS,
proxy_rotation_strategy=proxy_strategy,
proxy_rotation_strategy=proxy_strategy
)
async with AsyncWebCrawler(config=browser_config) as crawler:
urls = ["https://httpbin.org/ip"] * (len(proxies) * 2) # Test each proxy twice
print(f"🚀 Testing {len(proxies)} proxies with rotation...")
results = await crawler.arun_many(urls=urls, config=run_config)
print("\n📈 Initializing crawler with proxy rotation...")
async with AsyncWebCrawler(config=browser_config) as crawler:
print("\n🚀 Starting batch crawl with proxy rotation...")
results = await crawler.arun_many(
urls=urls,
config=run_config
)
for result in results:
if result.success:
ip_match = re.search(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}', result.html)
current_proxy = run_config.proxy_config if run_config.proxy_config else None
for i, result in enumerate(results):
if result.success:
# Extract IP from response
ip_match = re.search(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}', result.html)
if ip_match:
detected_ip = ip_match.group(0)
proxy_index = i % len(proxies)
expected_ip = proxies[proxy_index].ip
if current_proxy and ip_match:
print(f"URL {result.url}")
print(f"Proxy {current_proxy.server} -> Response IP: {ip_match.group(0)}")
verified = ip_match.group(0) == current_proxy.ip
if verified:
print(f"✅ Proxy working! IP matches: {current_proxy.ip}")
else:
print("❌ Proxy failed or IP mismatch!")
print("---")
print(f"✅ Request {i+1}: Proxy {proxy_index+1} -> IP {detected_ip}")
if detected_ip == expected_ip:
print(" 🎯 IP matches proxy configuration")
else:
print(f" ⚠️ IP mismatch (expected {expected_ip})")
else:
print(f"❌ Request {i+1}: Could not extract IP from response")
else:
print(f"❌ Request {i+1}: Failed - {result.error_message}")
asyncio.run(main())
if __name__ == "__main__":
asyncio.run(main())
```
## SSL Certificate Analysis
Combine proxy usage with SSL certificate inspection for enhanced security analysis. SSL certificate fetching is configured per request via `CrawlerRunConfig`.
### Per-Request SSL Certificate Analysis
```python
import asyncio
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig
run_config = CrawlerRunConfig(
proxy_config={
"server": "http://proxy.example.com:8080",
"username": "user",
"password": "pass",
},
fetch_ssl_certificate=True, # Enable SSL certificate analysis for this request
)
async def main():
browser_config = BrowserConfig()
async with AsyncWebCrawler(config=browser_config) as crawler:
result = await crawler.arun(url="https://example.com", config=run_config)
if result.success:
print(f"✅ Crawled via proxy: {result.url}")
# Analyze SSL certificate
if result.ssl_certificate:
cert = result.ssl_certificate
print("🔒 SSL Certificate Info:")
print(f" Issuer: {cert.issuer}")
print(f" Subject: {cert.subject}")
print(f" Valid until: {cert.valid_until}")
print(f" Fingerprint: {cert.fingerprint}")
# Export certificate
cert.to_json("certificate.json")
print("💾 Certificate exported to certificate.json")
else:
print("⚠️ No SSL certificate information available")
if __name__ == "__main__":
asyncio.run(main())
```
## Security Best Practices
### 1. Proxy Rotation for Anonymity
```python
from crawl4ai import CrawlerRunConfig, ProxyConfig
from crawl4ai.proxy_strategy import RoundRobinProxyStrategy
# Use multiple proxies to avoid IP blocking
proxies = ProxyConfig.from_env("PROXIES")
strategy = RoundRobinProxyStrategy(proxies)
# Configure rotation per request (recommended)
run_config = CrawlerRunConfig(proxy_rotation_strategy=strategy)
# For a fixed proxy across all requests, just reuse the same run_config instance
static_run_config = run_config
```
### 2. SSL Certificate Verification
```python
from crawl4ai import CrawlerRunConfig
# Always verify SSL certificates when possible
# Per-request (affects specific requests)
run_config = CrawlerRunConfig(fetch_ssl_certificate=True)
```
### 3. Environment Variable Security
```bash
# Use environment variables for sensitive proxy credentials
# Avoid hardcoding usernames/passwords in code
export PROXIES="ip1:port1:user1:pass1,ip2:port2:user2:pass2"
```
### 4. SOCKS5 for Enhanced Security
```python
from crawl4ai import CrawlerRunConfig
# Prefer SOCKS5 proxies for better protocol support
run_config = CrawlerRunConfig(proxy_config="socks5://proxy.example.com:1080")
```
## Migration from Deprecated `proxy` Parameter
- "Deprecation Notice"
The legacy `proxy` argument on `BrowserConfig` is deprecated. Configure proxies through `CrawlerRunConfig.proxy_config` so each request fully describes its network settings.
```python
# Old (deprecated) approach
# from crawl4ai import BrowserConfig
# browser_config = BrowserConfig(proxy="http://proxy.example.com:8080")
# New (preferred) approach
from crawl4ai import CrawlerRunConfig
run_config = CrawlerRunConfig(proxy_config="http://proxy.example.com:8080")
```
### Safe Logging of Proxies
```python
from crawl4ai import ProxyConfig
def safe_proxy_repr(proxy: ProxyConfig):
if getattr(proxy, "username", None):
return f"{proxy.server} (auth: ****)"
return proxy.server
```
## Troubleshooting
### Common Issues
- "Proxy connection failed"
- Verify the proxy server is reachable from your network.
- Double-check authentication credentials.
- Ensure the protocol matches (`http`, `https`, or `socks5`).
- "SSL certificate errors"
- Some proxies break SSL inspection; switch proxies if you see repeated failures.
- Consider temporarily disabling certificate fetching to isolate the issue.
- "Environment variables not loading"
- Confirm `PROXIES` (or your custom env var) is set before running the script.
- Check formatting: `ip:port:user:pass,ip:port:user:pass`.
- "Proxy rotation not working"
- Ensure `ProxyConfig.from_env()` actually loaded entries (`len(proxies) > 0`).
- Attach `proxy_rotation_strategy` to `CrawlerRunConfig`.
- Validate the proxy definitions you pass into the strategy.

# 🚀 Crawl4AI v0.7.7: The Self-Hosting & Monitoring Update
*November 14, 2025 • 10 min read*
---
Today I'm releasing Crawl4AI v0.7.7—the Self-Hosting & Monitoring Update. This release transforms Crawl4AI Docker from a simple containerized crawler into a complete self-hosting platform with enterprise-grade real-time monitoring, full operational transparency, and production-ready observability.
## 🎯 What's New at a Glance
- **📊 Real-time Monitoring Dashboard**: Interactive web UI with live system metrics and browser pool status
- **🔌 Comprehensive Monitor API**: Complete REST API for programmatic access to all monitoring data
- **⚡ WebSocket Streaming**: Real-time updates every 2 seconds for custom dashboards
- **🎮 Control Actions**: Manual browser management (kill, restart, cleanup)
- **🔥 Smart Browser Pool**: 3-tier architecture (permanent/hot/cold) with automatic promotion
- **🧹 Janitor Cleanup System**: Automatic resource management with event logging
- **📈 Production Metrics**: 6 critical metrics for operational excellence
- **🏭 Integration Ready**: Prometheus, alerting, and log aggregation examples
- **🐛 Critical Bug Fixes**: Async LLM extraction, DFS crawling, viewport config, and more
## 📊 Real-time Monitoring Dashboard: Complete Visibility
**The Problem:** Running Crawl4AI in Docker was like flying blind. Users had no visibility into what was happening inside the container—memory usage, active requests, browser pools, or errors. Troubleshooting required checking logs, and there was no way to monitor performance or manually intervene when issues occurred.
**My Solution:** I built a complete real-time monitoring system with an interactive dashboard, comprehensive REST API, WebSocket streaming, and manual control actions. Now you have full transparency and control over your crawling infrastructure.
### The Self-Hosting Value Proposition
Before v0.7.7, Docker was just a containerized crawler. After v0.7.7, it's a complete self-hosting platform that gives you:
- **🔒 Data Privacy**: Your data never leaves your infrastructure
- **💰 Cost Control**: No per-request pricing or rate limits
- **🎯 Full Customization**: Complete control over configurations and strategies
- **📊 Complete Transparency**: Real-time visibility into every aspect
- **⚡ Performance**: Direct access without network overhead
- **🛡️ Enterprise Security**: Keep workflows behind your firewall
### Interactive Monitoring Dashboard
Access the dashboard at `http://localhost:11235/dashboard` to see:
- **System Health Overview**: CPU, memory, network, and uptime in real-time
- **Live Request Tracking**: Active and completed requests with full details
- **Browser Pool Management**: Interactive table with permanent/hot/cold browsers
- **Janitor Events Log**: Automatic cleanup activities
- **Error Monitoring**: Full context error logs
The dashboard updates every 2 seconds via WebSocket, giving you live visibility into your crawling operations.
## 🔌 Monitor API: Programmatic Access
**The Problem:** Monitoring dashboards are great for humans, but automation and integration require programmatic access.
**My Solution:** A comprehensive REST API that exposes all monitoring data for integration with your existing infrastructure.
### System Health Endpoint
```python
import httpx
import asyncio
async def monitor_system_health():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/health")
health = response.json()
print(f"Container Metrics:")
print(f" CPU: {health['container']['cpu_percent']:.1f}%")
print(f" Memory: {health['container']['memory_percent']:.1f}%")
print(f" Uptime: {health['container']['uptime_seconds']}s")
print(f"\nBrowser Pool:")
print(f" Permanent: {health['pool']['permanent']['active']} active")
print(f" Hot Pool: {health['pool']['hot']['count']} browsers")
print(f" Cold Pool: {health['pool']['cold']['count']} browsers")
print(f"\nStatistics:")
print(f" Total Requests: {health['stats']['total_requests']}")
print(f" Success Rate: {health['stats']['success_rate_percent']:.1f}%")
print(f" Avg Latency: {health['stats']['avg_latency_ms']:.0f}ms")
asyncio.run(monitor_system_health())
```
### Request Tracking
```python
async def track_requests():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/requests")
requests_data = response.json()
print(f"Active Requests: {len(requests_data['active'])}")
print(f"Completed Requests: {len(requests_data['completed'])}")
# See details of recent requests
for req in requests_data['completed'][:5]:
status_icon = "" if req['success'] else ""
print(f"{status_icon} {req['endpoint']} - {req['latency_ms']:.0f}ms")
```
### Browser Pool Management
```python
async def monitor_browser_pool():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/browsers")
browsers = response.json()
print(f"Pool Summary:")
print(f" Total Browsers: {browsers['summary']['total_count']}")
print(f" Total Memory: {browsers['summary']['total_memory_mb']} MB")
print(f" Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
# List all browsers
for browser in browsers['permanent']:
print(f"🔥 Permanent: {browser['browser_id'][:8]}... | "
f"Requests: {browser['request_count']} | "
f"Memory: {browser['memory_mb']:.0f} MB")
```
### Endpoint Performance Statistics
```python
async def get_endpoint_stats():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/endpoints/stats")
stats = response.json()
print("Endpoint Analytics:")
for endpoint, data in stats.items():
print(f" {endpoint}:")
print(f" Requests: {data['count']}")
print(f" Avg Latency: {data['avg_latency_ms']:.0f}ms")
print(f" Success Rate: {data['success_rate_percent']:.1f}%")
```
### Complete API Reference
The Monitor API includes these endpoints:
- `GET /monitor/health` - System health with pool statistics
- `GET /monitor/requests` - Active and completed request tracking
- `GET /monitor/browsers` - Browser pool details and efficiency
- `GET /monitor/endpoints/stats` - Per-endpoint performance analytics
- `GET /monitor/timeline?minutes=5` - Time-series data for charts
- `GET /monitor/logs/janitor?limit=10` - Cleanup activity logs
- `GET /monitor/logs/errors?limit=10` - Error logs with context
- `POST /monitor/actions/cleanup` - Force immediate cleanup
- `POST /monitor/actions/kill_browser` - Kill specific browser
- `POST /monitor/actions/restart_browser` - Restart browser
- `POST /monitor/stats/reset` - Reset accumulated statistics
## ⚡ WebSocket Streaming: Real-time Updates
**The Problem:** Polling the API every few seconds wastes resources and adds latency. Real-time dashboards need instant updates.
**My Solution:** WebSocket streaming with 2-second update intervals for building custom real-time dashboards.
### WebSocket Integration Example
```python
import websockets
import json
import asyncio
async def monitor_realtime():
uri = "ws://localhost:11235/monitor/ws"
async with websockets.connect(uri) as websocket:
print("Connected to real-time monitoring stream")
while True:
# Receive update every 2 seconds
data = await websocket.recv()
update = json.loads(data)
# Access all monitoring data
print(f"\n--- Update at {update['timestamp']} ---")
print(f"Memory: {update['health']['container']['memory_percent']:.1f}%")
print(f"Active Requests: {len(update['requests']['active'])}")
print(f"Total Browsers: {update['browsers']['summary']['total_count']}")
if update['errors']:
print(f"⚠️ Recent Errors: {len(update['errors'])}")
asyncio.run(monitor_realtime())
```
**Expected Real-World Impact:**
- **Custom Dashboards**: Build tailored monitoring UIs for your team
- **Real-time Alerting**: Trigger alerts instantly when metrics exceed thresholds
- **Integration**: Feed live data into monitoring tools like Grafana
- **Automation**: React to events in real-time without polling
## 🔥 Smart Browser Pool: 3-Tier Architecture
**The Problem:** Creating a new browser for every request is slow and memory-intensive. Traditional browser pools are static and inefficient.
**My Solution:** A smart 3-tier browser pool that automatically adapts to usage patterns.
### How It Works
```python
import httpx
async def demonstrate_browser_pool():
async with httpx.AsyncClient() as client:
# Request 1-3: Default config → Uses permanent browser
print("Phase 1: Using permanent browser")
for i in range(3):
await client.post(
"http://localhost:11235/crawl",
json={"urls": [f"https://httpbin.org/html?req={i}"]}
)
print(f" Request {i+1}: Reused permanent browser")
# Request 4-6: Custom viewport → Cold pool (first use)
print("\nPhase 2: Custom config creates cold pool browser")
viewport_config = {"viewport": {"width": 1280, "height": 720}}
for i in range(4):
await client.post(
"http://localhost:11235/crawl",
json={
"urls": [f"https://httpbin.org/json?v={i}"],
"browser_config": viewport_config
}
)
if i < 2:
print(f" Request {i+1}: Cold pool browser")
else:
print(f" Request {i+1}: Promoted to hot pool! (after 3 uses)")
# Check pool status
response = await client.get("http://localhost:11235/monitor/browsers")
browsers = response.json()
print(f"\nPool Status:")
print(f" Permanent: {len(browsers['permanent'])} (always active)")
print(f" Hot: {len(browsers['hot'])} (frequently used configs)")
print(f" Cold: {len(browsers['cold'])} (on-demand)")
print(f" Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
asyncio.run(demonstrate_browser_pool())
```
**Pool Tiers:**
- **🔥 Permanent Browser**: Always-on, default configuration, instant response
- **♨️ Hot Pool**: Browsers promoted after 3+ uses, kept warm for quick access
- **❄️ Cold Pool**: On-demand browsers for variant configs, cleaned up when idle
**Expected Real-World Impact:**
- **Memory Efficiency**: 10x reduction in memory usage vs creating browsers per request
- **Performance**: Instant access to frequently-used configurations
- **Automatic Optimization**: Pool adapts to your usage patterns
- **Resource Management**: Janitor automatically cleans up idle browsers
## 🧹 Janitor System: Automatic Cleanup
**The Problem:** Long-running crawlers accumulate idle browsers and consume memory over time.
**My Solution:** An automatic janitor system that monitors and cleans up idle resources.
```python
async def monitor_janitor_activity():
async with httpx.AsyncClient() as client:
response = await client.get("http://localhost:11235/monitor/logs/janitor?limit=5")
logs = response.json()
print("Recent Cleanup Activities:")
for log in logs:
print(f" {log['timestamp']}: {log['message']}")
# Example output:
# 2025-11-14 10:30:00: Cleaned up 2 cold pool browsers (idle > 5min)
# 2025-11-14 10:25:00: Browser reuse rate: 85.3%
# 2025-11-14 10:20:00: Hot pool browser promoted (10 requests)
```
## 🎮 Control Actions: Manual Management
**The Problem:** Sometimes you need to manually intervene—kill a stuck browser, force cleanup, or restart resources.
**My Solution:** Manual control actions via the API for operational troubleshooting.
### Force Cleanup
```python
async def force_cleanup():
async with httpx.AsyncClient() as client:
response = await client.post("http://localhost:11235/monitor/actions/cleanup")
result = response.json()
print(f"Cleanup completed:")
print(f" Browsers cleaned: {result.get('cleaned_count', 0)}")
print(f" Memory freed: {result.get('memory_freed_mb', 0):.1f} MB")
```
### Kill Specific Browser
```python
async def kill_stuck_browser(browser_id: str):
async with httpx.AsyncClient() as client:
response = await client.post(
"http://localhost:11235/monitor/actions/kill_browser",
json={"browser_id": browser_id}
)
if response.status_code == 200:
print(f"✅ Browser {browser_id} killed successfully")
```
### Reset Statistics
```python
async def reset_stats():
async with httpx.AsyncClient() as client:
response = await client.post("http://localhost:11235/monitor/stats/reset")
print("📊 Statistics reset for fresh monitoring")
```
## 📈 Production Integration Patterns
### Prometheus Integration
```python
# Export metrics for Prometheus scraping
async def export_prometheus_metrics():
async with httpx.AsyncClient() as client:
health = await client.get("http://localhost:11235/monitor/health")
data = health.json()
# Export in Prometheus format
metrics = f"""
# HELP crawl4ai_memory_usage_percent Memory usage percentage
# TYPE crawl4ai_memory_usage_percent gauge
crawl4ai_memory_usage_percent {data['container']['memory_percent']}
# HELP crawl4ai_request_success_rate Request success rate
# TYPE crawl4ai_request_success_rate gauge
crawl4ai_request_success_rate {data['stats']['success_rate_percent']}
# HELP crawl4ai_browser_pool_count Total browsers in pool
# TYPE crawl4ai_browser_pool_count gauge
crawl4ai_browser_pool_count {data['pool']['permanent']['active'] + data['pool']['hot']['count'] + data['pool']['cold']['count']}
"""
return metrics
```
### Alerting Example
```python
async def check_alerts():
async with httpx.AsyncClient() as client:
health = await client.get("http://localhost:11235/monitor/health")
data = health.json()
# Memory alert

## 🐛 Critical Bug Fixes
This release includes significant bug fixes that improve stability and performance:
### Async LLM Extraction (#1590)
**The Problem:** LLM extraction was blocking async execution, causing URLs to be processed sequentially instead of in parallel (issue #1055).
**The Fix:** Resolved the blocking issue to enable true parallel processing for LLM extraction.
```python
# Before v0.7.7: Sequential processing
# After v0.7.7: True parallel processing
async with AsyncWebCrawler() as crawler:
urls = ["url1", "url2", "url3", "url4"]
# Now processes truly in parallel with LLM extraction
results = await crawler.arun_many(
urls,
config=CrawlerRunConfig(
extraction_strategy=LLMExtractionStrategy(...)
)
)
# 4x faster for parallel LLM extraction!
```
**Expected Impact:** Major performance improvement for batch LLM extraction workflows.
### DFS Deep Crawling (#1607)
**The Problem:** DFS (Depth-First Search) deep crawl strategy had implementation issues.
**The Fix:** Enhanced DFSDeepCrawlStrategy with proper seen URL tracking and improved documentation.
### Browser & Crawler Config Documentation (#1609)
**The Problem:** Documentation didn't match the actual `async_configs.py` implementation.
**The Fix:** Updated all configuration documentation to accurately reflect the current implementation.
### Sitemap Seeder (#1598)
**The Problem:** Sitemap parsing and URL normalization issues in AsyncUrlSeeder (issue #1559).
**The Fix:** Added comprehensive tests and fixes for sitemap namespace parsing and URL normalization.
### Remove Overlay Elements (#1529)
**The Problem:** The `remove_overlay_elements` functionality wasn't working (issue #1396).
**The Fix:** Fixed by properly calling the injected JavaScript function.
### Viewport Configuration (#1495)
**The Problem:** Viewport configuration wasn't working in managed browsers (issue #1490).
**The Fix:** Added proper viewport size configuration support for browser launch.
### Managed Browser CDP Timing (#1528)
**The Problem:** CDP (Chrome DevTools Protocol) endpoint verification had timing issues causing connection failures (issue #1445).
**The Fix:** Added exponential backoff for CDP endpoint verification to handle timing variations.
### Security Updates
- **pyOpenSSL**: Updated from >=24.3.0 to >=25.3.0 to address security vulnerability
- Added verification tests for the security update
### Docker Fixes
- **Port Standardization**: Fixed inconsistent port usage (11234 vs 11235) - now standardized to 11235
- **LLM Environment**: Fixed LLM API key handling for multi-provider support (PR #1537)
- **Error Handling**: Improved Docker API error messages with comprehensive status codes
- **Serialization**: Fixed `fit_html` property serialization in `/crawl` and `/crawl/stream` endpoints
### Other Important Fixes
- **arun_many Returns**: Fixed function to always return a list, even on exception (PR #1530)
- **Webhook Serialization**: Properly serialize Pydantic HttpUrl in webhook config
- **LLMConfig Documentation**: Fixed casing and variable name consistency (issue #1551)
- **Python Version**: Dropped Python 3.9 support, now requires Python >=3.10

# Crawl4AI v0.7.8: Stability & Bug Fix Release
*December 2025*
---
I'm releasing Crawl4AI v0.7.8—a focused stability release that addresses 11 bugs reported by the community. While there are no new features in this release, these fixes resolve important issues affecting Docker deployments, LLM extraction, URL handling, and dependency compatibility.
## What's Fixed at a Glance
- **Docker API**: Fixed ContentRelevanceFilter deserialization, ProxyConfig serialization, and cache folder permissions
- **LLM Extraction**: Configurable rate limiter backoff, HTML input format support, and proper URL handling for raw HTML
- **URL Handling**: Correct relative URL resolution after JavaScript redirects
- **Dependencies**: Replaced deprecated PyPDF2 with pypdf, Pydantic v2 ConfigDict compatibility
- **AdaptiveCrawler**: Fixed query expansion to actually use LLM instead of hardcoded mock data
## Bug Fixes
### Docker & API Fixes
#### ContentRelevanceFilter Deserialization (#1642)
**The Problem:** When sending deep crawl requests to the Docker API with `ContentRelevanceFilter`, the server failed to deserialize the filter, causing requests to fail.
**The Fix:** I added `ContentRelevanceFilter` to the public exports and enhanced the deserialization logic with dynamic imports.
```python
# This now works correctly in Docker API
import httpx
request = {
"urls": ["https://docs.example.com"],
"crawler_config": {
"deep_crawl_strategy": {
"type": "BFSDeepCrawlStrategy",
"max_depth": 2,
"filter_chain": [
{
"type": "ContentRelevanceFilter",
"query": "API documentation",
"threshold": 0.3
}
]
}
}
}
async with httpx.AsyncClient() as client:
response = await client.post("http://localhost:11235/crawl", json=request)
# Previously failed, now works!
```
#### ProxyConfig JSON Serialization (#1629)
**The Problem:** `BrowserConfig.to_dict()` failed when `proxy_config` was set because `ProxyConfig` wasn't being serialized to a dictionary.
**The Fix:** `ProxyConfig.to_dict()` is now called during serialization.
```python
from crawl4ai import BrowserConfig
from crawl4ai.async_configs import ProxyConfig
proxy = ProxyConfig(
server="http://proxy.example.com:8080",
username="user",
password="pass"
)
config = BrowserConfig(headless=True, proxy_config=proxy)
# Previously raised TypeError, now works
config_dict = config.to_dict()
json.dumps(config_dict) # Valid JSON
```
#### Docker Cache Folder Permissions (#1638)
**The Problem:** The `.cache` folder in the Docker image had incorrect permissions, causing crawling to fail when caching was enabled.
**The Fix:** Corrected ownership and permissions during image build.
```bash
# Cache now works correctly in Docker
docker run -d -p 11235:11235 \
--shm-size=1g \
-v ./my-cache:/app/.cache \
unclecode/crawl4ai:0.7.8
```
---
### LLM & Extraction Fixes
#### Configurable Rate Limiter Backoff (#1269)
**The Problem:** The LLM rate limiting backoff parameters were hardcoded, making it impossible to adjust retry behavior for different API rate limits.
**The Fix:** `LLMConfig` now accepts three new parameters for complete control over retry behavior.
```python
from crawl4ai import LLMConfig
# Default behavior (unchanged)
default_config = LLMConfig(provider="openai/gpt-4o-mini")
# backoff_base_delay=2, backoff_max_attempts=3, backoff_exponential_factor=2
# Custom configuration for APIs with strict rate limits
custom_config = LLMConfig(
provider="openai/gpt-4o-mini",
backoff_base_delay=5, # Wait 5 seconds on first retry
backoff_max_attempts=5, # Try up to 5 times
backoff_exponential_factor=3 # Multiply delay by 3 each attempt
)
# Retry sequence: 5s -> 15s -> 45s -> 135s -> 405s
```
#### LLM Strategy HTML Input Support (#1178)
**The Problem:** `LLMExtractionStrategy` always sent markdown to the LLM, but some extraction tasks work better with HTML structure preserved.
**The Fix:** Added `input_format` parameter supporting `"markdown"`, `"html"`, `"fit_markdown"`, `"cleaned_html"`, and `"fit_html"`.
```python
from crawl4ai import LLMExtractionStrategy, LLMConfig
# Default: markdown input (unchanged)
markdown_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini"),
instruction="Extract product information"
)
# NEW: HTML input - preserves table/list structure
html_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini"),
instruction="Extract the data table preserving structure",
input_format="html"
)
# NEW: Filtered markdown - only relevant content
fit_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini"),
instruction="Summarize the main content",
input_format="fit_markdown"
)
```
#### Raw HTML URL Variable (#1116)
**The Problem:** When using `url="raw:<html>..."`, the entire HTML content was being passed to extraction strategies as the URL parameter, polluting LLM prompts.
**The Fix:** The URL is now correctly set to `"Raw HTML"` for raw HTML inputs.
```python
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
html = "<html><body><h1>Test</h1></body></html>"
async with AsyncWebCrawler() as crawler:
result = await crawler.arun(
url=f"raw:{html}",
config=CrawlerRunConfig(extraction_strategy=my_strategy)
)
# extraction_strategy receives url="Raw HTML" instead of the HTML blob
```
---
### URL Handling Fix
#### Relative URLs After Redirects (#1268)
**The Problem:** When JavaScript caused a page redirect, relative links were resolved against the original URL instead of the final URL.
**The Fix:** `redirected_url` now captures the actual page URL after all JavaScript execution completes.
```python
from crawl4ai import AsyncWebCrawler
async with AsyncWebCrawler() as crawler:
# Page at /old-page redirects via JS to /new-page
result = await crawler.arun(url="https://example.com/old-page")
# BEFORE: redirected_url = "https://example.com/old-page"
# AFTER: redirected_url = "https://example.com/new-page"
# Links are now correctly resolved against the final URL
for link in result.links['internal']:
print(link['href']) # Relative links resolved correctly
```
---
### Dependency & Compatibility Fixes
#### PyPDF2 Replaced with pypdf (#1412)
**The Problem:** PyPDF2 was deprecated in 2022 and is no longer maintained.
**The Fix:** Replaced with the actively maintained `pypdf` library.
```python
# Installation (unchanged)
pip install crawl4ai[pdf]
# The PDF processor now uses pypdf internally
# No code changes required - API remains the same
```
#### Pydantic v2 ConfigDict Compatibility (#678)
**The Problem:** Using the deprecated `class Config` syntax caused deprecation warnings with Pydantic v2.
**The Fix:** Migrated to `model_config = ConfigDict(...)` syntax.
```python
# No more deprecation warnings when importing crawl4ai models
from crawl4ai.models import CrawlResult
from crawl4ai import CrawlerRunConfig, BrowserConfig
# All models are now Pydantic v2 compatible
```
---
### AdaptiveCrawler Fix
#### Query Expansion Using LLM (#1621)
**The Problem:** The `EmbeddingStrategy` in AdaptiveCrawler had commented-out LLM code and was using hardcoded mock query variations instead.
**The Fix:** Uncommented and activated the LLM call for actual query expansion.
```python
# AdaptiveCrawler query expansion now actually uses the LLM
# Instead of hardcoded variations like:
# variations = {'queries': ['what are the best vegetables...']}
# The LLM generates relevant query variations based on your actual query
```
---
### Code Formatting Fix
#### Import Statement Formatting (#1181)
**The Problem:** When extracting code from web pages, import statements were sometimes concatenated without proper line separation.
**The Fix:** Import statements now maintain proper newline separation.
```python
# BEFORE: "import osimport sysfrom pathlib import Path"
# AFTER:
# import os
# import sys
# from pathlib import Path
```
---
## Breaking Changes
**None!** This release is fully backward compatible.
- All existing code continues to work without modification
- New parameters have sensible defaults matching previous behavior
- No API changes to existing functionality
---
## Upgrade Instructions
### Python Package
```bash
pip install --upgrade crawl4ai
# or

- `backoff_base_delay` *(default `2` seconds)* how long to pause before the first retry if the provider rate-limits you.
- `backoff_max_attempts` *(default `3`)* total tries for the same prompt (initial call + retries).
- `backoff_exponential_factor` *(default `2`)* how quickly the pause grows between retries. A factor of 2 yields waits like 2s → 4s → 8s.

## Real-time Monitoring & Operations
## Metrics & Monitoring
One of the key advantages of self-hosting is complete visibility into your infrastructure. Crawl4AI includes a comprehensive real-time monitoring system that gives you full transparency and control.
Keep an eye on your crawler with these endpoints:
### Monitoring Dashboard
Access the **built-in real-time monitoring dashboard** for complete operational visibility:
```
http://localhost:11235/monitor
```
![Monitoring Dashboard](https://via.placeholder.com/800x400?text=Crawl4AI+Monitoring+Dashboard)
**Dashboard Features:**
#### 1. System Health Overview
- **CPU & Memory**: Live usage with progress bars and percentage indicators
- **Network I/O**: Total bytes sent/received since startup
- **Server Uptime**: How long your server has been running
- **Browser Pool Status**:
- 🔥 Permanent browser (always-on default config, ~270MB)
- ♨️ Hot pool (frequently used configs, ~180MB each)
- ❄️ Cold pool (idle browsers awaiting cleanup, ~180MB each)
- **Memory Pressure**: LOW/MEDIUM/HIGH indicator for janitor behavior
#### 2. Live Request Tracking
- **Active Requests**: Currently running crawls with:
- Request ID for tracking
- Target URL (truncated for display)
- Endpoint being used
- Elapsed time (updates in real-time)
- Memory usage from start
- **Completed Requests**: Last 10 finished requests showing:
- Success/failure status (color-coded)
- Total execution time
- Memory delta (how much memory changed)
- Pool hit (was browser reused?)
- HTTP status code
- **Filtering**: View all, success only, or errors only
#### 3. Browser Pool Management
Interactive table showing all active browsers:
| Type | Signature | Age | Last Used | Hits | Actions |
|------|-----------|-----|-----------|------|---------|
| permanent | abc12345 | 2h | 5s ago | 1,247 | Restart |
| hot | def67890 | 45m | 2m ago | 89 | Kill / Restart |
| cold | ghi11213 | 30m | 15m ago | 3 | Kill / Restart |
- **Reuse Rate**: Percentage of requests that reused existing browsers
- **Memory Estimates**: Total memory used by browser pool
- **Manual Control**: Kill or restart individual browsers
#### 4. Janitor Events Log
Real-time log of browser pool cleanup events:
- When cold browsers are closed due to memory pressure
- When browsers are promoted from cold to hot pool
- Forced cleanups triggered manually
- Detailed cleanup reasons and browser signatures
#### 5. Error Monitoring
Recent errors with full context:
- Timestamp
- Endpoint where error occurred
- Target URL
- Error message
- Request ID for correlation
**Live Updates:**
The dashboard connects via WebSocket and refreshes every **2 seconds** with the latest data. Connection status indicator shows when you're connected/disconnected.

```
---
### WebSocket Streaming
For real-time monitoring in your own dashboards or applications:
```bash
WS /monitor/ws
```
**Connection Example (Python):**
```python
import asyncio
import websockets
import json
async def monitor_server():
uri = "ws://localhost:11235/monitor/ws"
async with websockets.connect(uri) as websocket:
print("Connected to Crawl4AI monitor")
while True:
# Receive update every 2 seconds
data = await websocket.recv()
update = json.loads(data)
# Extract key metrics
health = update['health']
active_requests = len(update['requests']['active'])
browsers = len(update['browsers'])
print(f"Memory: {health['container']['memory_percent']:.1f}% | "
f"Active: {active_requests} | "
f"Browsers: {browsers}")
# Check for high memory pressure
if health['janitor']['memory_pressure'] == 'HIGH':
print("⚠️ HIGH MEMORY PRESSURE - Consider cleanup")
asyncio.run(monitor_server())
```
**Update Payload Structure:**
```json
{
"timestamp": 1699564823.456,
"health": { /* System health snapshot */ },
"requests": {
"active": [ /* Currently running */ ],
"completed": [ /* Last 10 completed */ ]
},
"browsers": [ /* All active browsers */ ],
"timeline": {
"memory": { /* Last 5 minutes */ },
"requests": { /* Request rate */ },
"browsers": { /* Pool composition */ }
},
"janitor": [ /* Last 10 cleanup events */ ],
"errors": [ /* Last 10 errors */ ]
}
```
---
### Control Actions
Take manual control when needed:
**Force Immediate Cleanup**
```bash
POST /monitor/actions/cleanup
```
Kills all cold pool browsers immediately (useful when memory is tight):
```json
{
"success": true,
"killed_browsers": 3
}
```
**Kill Specific Browser**
```bash
POST /monitor/actions/kill_browser
Content-Type: application/json
{
"sig": "abc12345" // First 8 chars of browser signature
}
```
Response:
```json
{
"success": true,
"killed_sig": "abc12345",
"pool_type": "hot"
}
```
**Restart Browser**
```bash
POST /monitor/actions/restart_browser
Content-Type: application/json
{
"sig": "permanent" // Or first 8 chars of signature
}
```
For permanent browser, this will close and reinitialize it. For hot/cold browsers, it kills them and lets new requests create fresh ones.
**Reset Statistics**
```bash
POST /monitor/stats/reset
```
Clears endpoint counters (useful for starting fresh after testing).
---
### Production Integration
#### Integration with Existing Monitoring Systems
**Prometheus Integration:**
```bash
# Scrape metrics endpoint
curl http://localhost:11235/metrics
```
**Custom Dashboard Integration:**
```python
# Example: Push metrics to your monitoring system
import asyncio
import websockets
import json
from your_monitoring import push_metric
async def integrate_monitoring():
async with websockets.connect("ws://localhost:11235/monitor/ws") as ws:
while True:
data = json.loads(await ws.recv())
# Push to your monitoring system
push_metric("crawl4ai.memory.percent",
data['health']['container']['memory_percent'])
push_metric("crawl4ai.active_requests",
len(data['requests']['active']))
push_metric("crawl4ai.browser_count",
len(data['browsers']))
```
**Alerting Example:**
```python
import requests
import time
def check_health():
"""Poll health endpoint and alert on issues"""
response = requests.get("http://localhost:11235/monitor/health")
health = response.json()
# Alert on high memory
if health['container']['memory_percent'] > 85:
send_alert(f"High memory: {health['container']['memory_percent']}%")
# Alert on high error rate
stats = requests.get("http://localhost:11235/monitor/endpoints/stats").json()
for endpoint, metrics in stats.items():
if metrics['success_rate_percent'] < 95:
send_alert(f"{endpoint} success rate: {metrics['success_rate_percent']}%")
# Run every minute
while True:
check_health()
time.sleep(60)
```
**Log Aggregation:**
```python
import requests
from datetime import datetime
def aggregate_errors():
"""Fetch and aggregate errors for logging system"""
response = requests.get("http://localhost:11235/monitor/logs/errors?limit=100")
errors = response.json()['errors']
for error in errors:
log_to_system({
'timestamp': datetime.fromtimestamp(error['timestamp']),
'service': 'crawl4ai',
'endpoint': error['endpoint'],
'url': error['url'],
'message': error['error'],
'request_id': error['request_id']
})
```
#### Key Metrics to Track
For production self-hosted deployments, monitor these metrics:
1. **Memory Usage Trends**
- Track `container.memory_percent` over time
- Alert when consistently above 80%
- Prevents OOM kills
2. **Request Success Rates**
- Monitor per-endpoint success rates
- Alert when below 95%
- Indicates crawling issues
3. **Average Latency**
- Track `avg_latency_ms` per endpoint
- Detect performance degradation
- Optimize slow endpoints
4. **Browser Pool Efficiency**
- Monitor `reuse_rate_percent`
- Should be >80% for good efficiency
- Low rates indicate pool churn
5. **Error Frequency**
- Count errors per time window
- Alert on sudden spikes
- Track error patterns
6. **Janitor Activity**
- Monitor cleanup frequency
- Excessive cleanup indicates memory pressure
- Adjust pool settings if needed

### Quick Health Check
For simple uptime monitoring:
- `/health` - Quick health check
- `/metrics` - Detailed Prometheus metrics
- `/schema` - Full API schema
Example health check:
```bash
curl http://localhost:11235/health
```
Returns:
```json
{
"status": "healthy",
"version": "0.7.4"
}
```

Crawl4AI v0.7.7 Release Demo
============================
This demo showcases the major feature in v0.7.7:
**Self-Hosting with Real-time Monitoring Dashboard**
Features Demonstrated:
1. System health monitoring with live metrics
2. Real-time request tracking (active & completed)
3. Browser pool management (permanent/hot/cold pools)
4. Monitor API endpoints for programmatic access
5. WebSocket streaming for real-time updates
6. Control actions (kill browser, cleanup, restart)
7. Production metrics (efficiency, reuse rates, memory)
Prerequisites:
- Crawl4AI Docker container running on localhost:11235
- Python packages: pip install httpx websockets
