Implements webhook support for the crawl job API to eliminate polling requirements.
Changes:
- Added WebhookConfig and WebhookPayload schemas to schemas.py
- Created webhook.py with WebhookDeliveryService class
- Integrated webhook notifications in api.py handle_crawl_job
- Updated job.py CrawlJobPayload to accept webhook_config
- Added webhook configuration section to config.yml
- Included comprehensive usage examples in WEBHOOK_EXAMPLES.md
Features:
- Webhook notifications on job completion (success/failure)
- Configurable data inclusion in webhook payload
- Custom webhook headers support
- Global default webhook URL configuration
- Exponential backoff retry logic (5 attempts: 1s, 2s, 4s, 8s, 16s)
- 30-second timeout per webhook call
Usage:
POST /crawl/job with optional webhook_config:
- webhook_url: URL to receive notifications

The app detail page was displaying hardcoded/templated content instead of
using actual data from the database. This prevented admins from controlling
the content shown in Overview, Integration, and Documentation tabs.
- Cross-checked every section against actual docs
- Fixed BM25ContentFilter parameters (user_query, bm25_threshold)
- Removed incorrect wait_for selector from basic example
- Added comprehensive test suite (4 test files)
- All examples now tested and verified working
- Tests validate: basic crawling, markdown generation, data extraction, advanced patterns
- Package size: 76.6 KB (includes tests for future validation)
- Create comprehensive skill package for AI coding assistants
- Include complete SDK reference (23K words, v0.7.4)
- Add three extraction scripts (basic, batch, pipeline)
- Implement version tracking in skill and scripts
- Add prominent download section on homepage
- Place skill in docs/assets for web distribution
The skill enables AI assistants like Claude, Cursor, and Windsurf
to effectively use Crawl4AI with optimized workflows for markdown
generation and data extraction.
Created ARCHITECTURE.md as a complete technical reference for the
Crawl4AI Docker server, replacing the stress test pipeline document
with production-grade documentation.
Contents:
- System overview with architecture diagrams
- Core components deep-dive (server, API, utils)
- Smart browser pool implementation details
- Real-time monitoring system architecture
- WebSocket implementation and fallback strategy
- Memory management and container detection
- Production optimizations and code review fixes
- Deployment guides (local, Docker, production)
- Comprehensive troubleshooting section
- Debug tools and performance tuning
- Test suite documentation
- Architecture decision log (ADRs)
Target audience: Developers maintaining or extending the system
Goal: Enable rapid onboarding and confident modifications
Backend Improvements (11 fixes applied):
Critical Fixes:
- Add lock protection for browser pool access in monitor stats
- Ensure async track_janitor_event across all call sites
- Improve error handling in monitor request tracking (already in place)
Important Fixes:
- Replace fire-and-forget Redis with background persistence worker
- Add time-based expiry for completed requests/errors (5min cleanup)
- Implement input validation for monitor route parameters
- Add 4s timeout to timeline updater to prevent hangs
- Add warning when killing browsers with active requests
- Implement monitor cleanup on shutdown with final persistence
- Document memory estimates with TODO for actual tracking
Frontend Enhancements:
WebSocket Real-time Updates:
- Add WebSocket endpoint at /monitor/ws for live monitoring
- Implement auto-reconnect with exponential backoff (max 5 attempts)
- Add graceful fallback to HTTP polling on WebSocket failure
- Send comprehensive updates every 2 seconds (health, requests, browsers, timeline, events)
UI/UX Improvements:
- Add live connection status indicator with pulsing animation
- Green "Live" = WebSocket connected
- Yellow "Connecting..." = Attempting connection
- Blue "Polling" = Fallback to HTTP polling
- Red "Disconnected" = Connection failed
- Restore original beautiful styling for all sections
- Improve request table layout with flex-grow for URL column
- Add browser type text labels alongside emojis
- Add flex layout to browser section header
Testing:
- Add test-websocket.py for WebSocket validation
- All 7 integration tests passing successfully
Summary: 563 additions across 6 files
- Introduced a demo script (`demo_monitor_dashboard.py`) to showcase various monitoring features through simulated activity.
- Implemented a test script (`test_monitor_demo.py`) to generate dashboard activity and verify monitor health and endpoint statistics.
- Added a logo image to the static assets for branding purposes.
Add hooks_to_string() utility function that converts Python function objects
to string representations for the Docker API, enabling developers to write hooks
as regular Python functions instead of strings.
Core Changes:
- New hooks_to_string() utility in crawl4ai/utils.py using inspect.getsource()
- Docker client now accepts both function objects and strings for hooks
- Automatic detection and conversion in Crawl4aiDockerClient._prepare_request()
- New hooks and hooks_timeout parameters in client.crawl() method
Documentation:
- Docker client examples with function-based hooks (docs/examples/docker_client_hooks_example.py)
- Updated main Docker deployment guide with comprehensive hooks section
- Added unit tests for hooks utility (tests/docker/test_hooks_utility.py)

- Fixed hero image to 200px height with min/max constraints
- Added object-fit: cover to hero-image img elements
- Changed secondary-featured align-items from stretch to flex-start
- Fixed secondary-card height to 118px (no flex: 1 stretching)
- Updated responsive grid layouts for wider screens
- Added flex: 1 to hero-content for better content distribution
These changes ensure a rigid, predictable layout that prevents:
1. Large images from pushing text content down
2. Single secondary cards from stretching to fill entire height
- Fixed JavaScript errors from missing HTML elements (install-code, usage-code, integration-code)
- Added missing CSS classes for tabs, overview layout, sidebar, and integration content
- Fixed tab navigation to display horizontally in single line
- Added proper padding to tab content sections (removed from container, added to content)
- Fixed tab selector from .nav-tab to .tab-btn to match HTML structure
- Added sidebar styling with stats grid and metadata display
- Improved responsive design with mobile-friendly tab scrolling
- Fixed code block positioning for copy buttons
- Removed margin from first headings to prevent extra spacing
- Added null checks for DOM elements in JavaScript to prevent errors
These changes resolve the routing issue where clicking on apps caused page redirects,
and fix the broken layout where CSS was not properly applied to the app detail page.
The docker-compose.yml had an `environment:` section with variable
substitutions (${VAR:-}) that was overriding values from .llm.env with
empty strings.
- Commented out the `environment:` section to prevent overwrites
- Added clear warning comment explaining the override behavior
- .llm.env values now load directly into container without interference
- Switch installs to pip install -r requirements.txt (tutorial and app docs)
- Update local run steps to python server.py and http://localhost:8000
- Set default PORT to 8000; update port-in-use commands and alt port 8001
- Replace unsupported :contains() example with accessible attribute selector
- Update example URLs in tutorial servers to 127.0.0.1:8000
- Add “Identity-based crawling” section with crwl profiles CLI workflow and code usage
- Replace legacy-docs note with sponsorship message in docs/md_v2/index.md
- Minor copy and consistency fixes across pages
- Change API_BASE to relative '/api' for production
- Move marketplace to /marketplace instead of /marketplace/frontend
- Update MkDocs navigation
- Fix logo path in marketplace index
- Implement marketplace frontend and admin dashboard
- Add FastAPI backend with environment-based configuration
