+# Crawl4AI DevOps Agent Context
+
+## Service Overview
+**Crawl4AI**: Browser-based web crawling service with AI extraction. Docker deployment with horizontal scaling (1-N containers), Redis coordination, Nginx load balancing.
+
+## Architecture Quick Reference
+
+```
+Client → Nginx:11235 → [crawl4ai-1, crawl4ai-2, ...crawl4ai-N] ← Redis
+                              ↓
+                         Monitor Dashboard
+```
+
+**Components:**
+- **Nginx**: Load balancer (round-robin API, sticky monitoring)
+- **Crawl4AI containers**: FastAPI + Playwright browsers
+- **Redis**: Container discovery (heartbeats 30s), monitoring data aggregation
+- **Monitor**: Real-time dashboard at `/dashboard`
+
+## CLI Commands
+
+### Start/Stop
+```bash
+crwl server start [-r N] [--port P] [--mode auto|single|swarm|compose] [--env-file F] [--image I]
+crwl server stop [--remove-volumes]
+crwl server restart [-r N]
+```
+
+### Management
+```bash
+crwl server status        # Show mode, replicas, port, uptime
+crwl server scale N       # Live scaling (Swarm/Compose only)
+crwl server logs [-f] [--tail N]
+```
+
+**Defaults**: replicas=1, port=11235, mode=auto, image=unclecode/crawl4ai:latest
+
+## Deployment Modes
+
+| Replicas | Mode | Load Balancer | Use Case |
+|----------|------|---------------|----------|
+| N=1 | single | None | Dev/testing |
+| N>1 | swarm | Built-in | Production (if `docker swarm init` done) |
+| N>1 | compose | Nginx | Production (fallback) |
+
+**Mode Detection** (when mode=auto):
+1. If N=1 → single
+2. If N>1 & Swarm active → swarm
+3. If N>1 & Swarm inactive → compose
+
+## File Locations

+~/.crawl4ai/server/
+├── state.json              # Current deployment state
+├── docker-compose.yml      # Generated compose file

+└── crawler_pool.py         # Browser pool (PERMANENT, HOT_POOL, COLD_POOL)
+```
+
+## Monitoring & Troubleshooting
+
+### Health Checks
+```bash
+curl http://localhost:11235/health              # Service health
+curl http://localhost:11235/monitor/containers  # Container discovery
+curl http://localhost:11235/monitor/requests    # Aggregated requests
+```
+
+### Dashboard
+- URL: `http://localhost:11235/dashboard/`
+- Features: Container filtering (All/C-1/C-2/C-3), real-time WebSocket, timeline charts
+- WebSocket: `/monitor/ws` (sticky sessions)
+
+### Common Issues
+
+**No containers showing in dashboard:**
+```bash
+docker exec <redis-container> redis-cli SMEMBERS monitor:active_containers
+docker exec <redis-container> redis-cli KEYS "monitor:heartbeat:*"
+```
+Wait 30s for heartbeat registration.
+
+**Load balancing not working:**
+```bash
+docker exec <nginx-container> cat /etc/nginx/nginx.conf | grep upstream
+docker logs <nginx-container> | grep error
+```
+Check Nginx upstream has no `ip_hash` for API endpoints.
+
+**Redis connection errors:**
+```bash
+docker logs <crawl4ai-container> | grep -i redis
+docker exec <crawl4ai-container> ping redis
+```
+Verify REDIS_HOST=redis, REDIS_PORT=6379.
+
+**Containers not scaling:**
+```bash
+# Swarm
+docker service ls
+docker service ps crawl4ai
+
+# Compose
+docker compose -f ~/.crawl4ai/server/docker-compose.yml ps
+docker compose -f ~/.crawl4ai/server/docker-compose.yml up -d --scale crawl4ai=N
+```
+
+### Redis Data Structure
+```
+monitor:active_containers              # SET: {container_ids}
+monitor:heartbeat:{cid}                # STRING: {id, hostname, last_seen} TTL=60s
+monitor:{cid}:active_requests          # STRING: JSON list, TTL=5min
+monitor:{cid}:completed                # STRING: JSON list, TTL=1h
+monitor:{cid}:janitor                  # STRING: JSON list, TTL=1h
+monitor:{cid}:errors                   # STRING: JSON list, TTL=1h
+monitor:endpoint_stats                 # STRING: JSON aggregate, TTL=24h
+```

+
+## Performance & Scaling
+
+### Resource Recommendations
+| Containers | Memory/Container | Total Memory | Use Case |
+|------------|-----------------|--------------|----------|
+| 1 | 4GB | 4GB | Development |
+| 3 | 4GB | 12GB | Small prod |
+| 5 | 4GB | 20GB | Medium prod |
+| 10 | 4GB | 40GB | Large prod |
+
+**Expected Throughput**: ~10 req/min per container (depends on crawl complexity)
+
+### Scaling Guidelines
+- **Horizontal**: Add replicas (`crwl server scale N`)
+- **Vertical**: Adjust `--memory 8G --cpus 4` in kwargs
+- **Browser Pool**: Permanent (1) + Hot pool (adaptive) + Cold pool (cleanup by janitor)
+
+### Redis Memory Usage
+- **Per container**: ~110KB (requests + events + errors + heartbeat)
+- **10 containers**: ~1.1MB
+- **Recommendation**: 256MB Redis is sufficient for <100 containers
+
+## Security Notes
+
+### Input Validation
+All CLI inputs validated:
+- Image name: alphanumeric + `.-/:_@` only, max 256 chars
+- Port: 1-65535
+- Replicas: 1-100
+- Env file: must exist and be readable
+- Container IDs: alphanumeric + `-_` only (prevents Redis injection)
+
+### Network Security
+- Nginx forwards to internal `crawl4ai` service (Docker network)
+- Monitor endpoints have NO authentication (add MONITOR_TOKEN env for security)
+- Redis is internal-only (no external port)
+
+### Recommended Production Setup
+```bash
+# Add authentication
+export MONITOR_TOKEN="your-secret-token"
+
+# Use Redis password
+redis:
+  command: redis-server --requirepass ${REDIS_PASSWORD}
+
+# Enable rate limiting in Nginx
+limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s;
+```
+
+## Common User Scenarios
+
+### Scenario 1: Fresh Deployment
+```bash
+crwl server start --replicas 3 --env-file .env
+# Wait for health check, then access http://localhost:11235/health
+```
+
+### Scenario 2: Scaling Under Load
+```bash
+crwl server scale 10
+# Live scaling, no downtime
+```
+
+### Scenario 3: Debugging Slow Requests
+```bash
+# Check dashboard
+open http://localhost:11235/dashboard/
+
+# Check container logs
+docker logs <slowest-container-id> --tail 100
+
+# Check browser pool
+curl http://localhost:11235/monitor/browsers | jq
+```
+
+### Scenario 4: Redis Connection Issues
+```bash
+# Check Redis connectivity
+docker exec <crawl4ai-container> nc -zv redis 6379
+
+# Check Redis logs
+docker logs <redis-container>
+
+# Restart containers (triggers reconnect with retry logic)
+crwl server restart
+```
+
+### Scenario 5: Container Not Appearing in Dashboard
+```bash
+# Wait 30s for heartbeat
+sleep 30
+
+# Check Redis
+docker exec <redis-container> redis-cli SMEMBERS monitor:active_containers
+
+# Check container logs for heartbeat errors
+docker logs <missing-container> | grep -i heartbeat
+```
+
+## Code Context for Advanced Debugging
+
+### Key Classes
+- `MonitorStats` (monitor.py): Tracks stats, Redis persistence, heartbeat worker
+- `ServerManager` (server_manager.py): CLI orchestration, mode detection
+- Browser pool globals: `PERMANENT`, `HOT_POOL`, `COLD_POOL`, `LOCK` (crawler_pool.py)
+
+### Critical Timeouts
+- Browser pool lock: 2s timeout (prevents deadlock)
+- WebSocket connection: 5s timeout
+- Health check: 30-60s timeout
+- Heartbeat interval: 30s, TTL: 60s
+- Redis retry: 3 attempts, backoff: 0.5s/1s/2s
+- Circuit breaker: 5 failures → 5min backoff
+
+### State Transitions
+```
+NOT_RUNNING → STARTING → HEALTHY → RUNNING
+                ↓           ↓
+            FAILED      UNHEALTHY → STOPPED
+```
+
+State file: `~/.crawl4ai/server/state.json` (atomic writes, fcntl locking)
+
+## Quick Diagnostic Commands
+
+```bash
+# Full system check
+crwl server status
+docker ps
+curl http://localhost:11235/health
+curl http://localhost:11235/monitor/containers | jq
+
+# Redis check
+docker exec <redis-container> redis-cli PING
+docker exec <redis-container> redis-cli INFO stats
+
+# Network check
+docker network ls
+docker network inspect <network-name>
+
+# Logs check
+docker logs <nginx-container> --tail 50
+docker logs <redis-container> --tail 50
+docker compose -f ~/.crawl4ai/server/docker-compose.yml logs --tail 100
+```
+
+## Agent Decision Tree
+
+**User reports slow crawling:**
+1. Check dashboard for active requests stuck → kill browser if >5min
+2. Check browser pool status → cleanup if hot/cold pool >10
+3. Check container CPU/memory → scale up if >80%
+4. Check Redis latency → restart Redis if >100ms
+
+**User reports missing containers:**
+1. Wait 30s for heartbeat
+2. Check `docker ps` vs dashboard count
+3. Check Redis SMEMBERS monitor:active_containers
+4. Check container logs for Redis connection errors
+5. Verify REDIS_HOST/PORT env vars
+
+**User reports 502/503 errors:**
+1. Check Nginx logs for upstream errors
+2. Check container health: `curl http://localhost:11235/health`
+3. Check if all containers are healthy: `docker ps`
+4. Restart Nginx: `docker restart <nginx-container>`
+
+**User wants to update image:**
+1. `crwl server stop`
+2. `docker pull unclecode/crawl4ai:latest`
+3. `crwl server start --replicas <previous-count>`

+
+## Core Components Deep Dive
+
+### 1. `server_manager.py` - Orchestration Engine
+
+**Role:** Manages Docker container lifecycle, auto-detects deployment mode.
+
+**Key Classes:**
+- `ServerManager` - Main orchestrator
+  - `start(replicas, mode, port, env_file, image)` → Deploy server
+  - `stop(remove_volumes)` → Teardown
+  - `status()` → Health check
+  - `scale(replicas)` → Live scaling
+  - `logs(follow, tail)` → Stream logs
+  - `cleanup(force)` → Emergency cleanup
+
+**State Management:**
+- File: `~/.crawl4ai/server_state.yml`
+- Schema: `{mode, replicas, port, image, started_at, containers[]}`
+- Atomic writes with lock file
+
+**Deployment Modes:**
+```python
+if replicas == 1:
+    mode = "single"  # docker run
+elif swarm_available():
+    mode = "swarm"   # docker stack deploy
+else:
+    mode = "compose" # docker-compose + nginx
+```
+
+**Container Naming:**
+- Single: `crawl4ai-server`
+- Swarm: `crawl4ai-stack_crawl4ai`
+- Compose: `crawl4ai-server-{1..N}`, `crawl4ai-nginx`
+
+**Networks:**
+- `crawl4ai-network` (bridge mode for all)
+
+**Volumes:**
+- `crawl4ai-redis-data` - Persistent queue
+- `crawl4ai-profiles` - Browser profiles
+
+**Health Checks:**
+- Endpoint: `http://localhost:{port}/health`
+- Timeout: 30s startup
+- Retry: 3 attempts
+
+---
+
+### 2. `server.py` - FastAPI Application
+
+**Role:** HTTP server exposing crawl API + monitoring.
+
+**Startup Flow:**
+```python
+app = FastAPI()
+@app.on_event("startup")
+async def startup():
+    init_crawler_pool()      # Pre-warm browsers
+    init_redis_connection()  # Job queue
+    start_monitor_collector() # Metrics
+```
+
+**Key Endpoints:**
+```
+POST /crawl          → api.py:crawl_endpoint()
+POST /crawl/stream   → api.py:crawl_stream_endpoint()
+POST /screenshot     → api.py:screenshot_endpoint()
+POST /pdf            → api.py:pdf_endpoint()
+GET  /health         → server.py:health_check()
+GET  /monitor        → monitor_routes.py:dashboard()
+WS   /monitor/ws     → monitor_routes.py:websocket_endpoint()
+GET  /playground     → static/playground/index.html
+```
+
+**Process Manager:**
+- Uses `supervisord` to manage:
+  - FastAPI server (port 11235)
+  - Redis (port 6379)
+  - Background workers
+
+**Environment:**
+```bash
+CRAWL4AI_PORT=11235
+REDIS_URL=redis://localhost:6379
+MAX_CONCURRENT_CRAWLS=5
+BROWSER_POOL_SIZE=3
+```
+
+---
+
+### 3. `api.py` - Crawl Endpoints
+
+**Main Endpoint:** `POST /crawl`
+
+**Request Schema:**
+```json
+{
+  "urls": ["https://example.com"],
+  "priority": 10,
+  "browser_config": {
+    "type": "BrowserConfig",
+    "params": {"headless": true, "viewport_width": 1920}
+  },
+  "crawler_config": {
+    "type": "CrawlerRunConfig",
+    "params": {"cache_mode": "bypass", "extraction_strategy": {...}}
+  }
+}
+```
+
+**Processing Flow:**
+```
+1. Validate request (Pydantic)
+2. Queue job → Redis
+3. Get browser from pool → crawler_pool.py
+4. Execute crawl → AsyncWebCrawler
+5. Apply hooks → hook_manager.py
+6. Return result (JSON)
+7. Release browser to pool
+```
+
+**Memory Management:**
+- Browser pool: Max 3 instances
+- LRU eviction when pool full
+- Explicit cleanup: `browser.close()` in finally block
+- Redis TTL: 1 hour for completed jobs
+
+**Error Handling:**
+```python
+try:
+    result = await crawler.arun(url, config)
+except PlaywrightError as e:
+    # Browser crash - release & recreate
+    await pool.invalidate(browser_id)
+except TimeoutError as e:
+    # Timeout - kill & retry
+    await crawler.kill()
+except Exception as e:
+    # Unknown - log & fail gracefully
+    logger.error(f"Crawl failed: {e}")
+```
+
+---
+
+### 4. `crawler_pool.py` - Browser Pool Manager
+
+**Role:** Manage persistent browser instances to avoid startup overhead.
+
+**Class:** `CrawlerPool`
+- `get_crawler()` → Lease browser (async with context manager)
+- `release_crawler(id)` → Return to pool
+- `warm_up(count)` → Pre-launch browsers
+- `cleanup()` → Close all browsers
+
+**Pool Strategy:**
+```python
+pool = {
+    "browser_1": {"crawler": AsyncWebCrawler(), "in_use": False},
+    "browser_2": {"crawler": AsyncWebCrawler(), "in_use": False},
+    "browser_3": {"crawler": AsyncWebCrawler(), "in_use": False},
+}
+
+async with pool.get_crawler() as crawler:
+    result = await crawler.arun(url)
+    # Auto-released on context exit
+```
+
+**Anti-Leak Mechanisms:**
+1. Context managers enforce cleanup
+2. Watchdog thread kills stale browsers (>10min idle)
+3. Max lifetime: 1 hour per browser
+4. Force GC after browser close
+
+---
+
+### 5. `monitor.py` + `monitor_routes.py` - Real-time Dashboard
+
+**Architecture:**
+```
+[Browser] <--WebSocket--> [monitor_routes.py] <--Events--> [monitor.py]
+                              ↓
+                          [Redis Pub/Sub]
+                              ↓
+                       [Metrics Collector]
+```
+
+**Metrics Collected:**
+- Requests/sec (sliding window)
+- Active crawls (real-time count)
+- Response times (p50, p95, p99)
+- Error rate (5min rolling)
+- Memory usage (RSS, heap)
+- Browser pool utilization
+
+**WebSocket Protocol:**
+```json
+// Server → Client
+{
+  "type": "metrics",
+  "data": {
+    "rps": 45.3,
+    "active_crawls": 12,
+    "p95_latency": 1234,
+    "error_rate": 0.02
+  }
+}
+
+// Client → Server
+{
+  "type": "subscribe",
+  "channels": ["metrics", "logs"]
+}
+```
+
+**Dashboard Route:** `/monitor`
+- Real-time graphs (Chart.js)
+- Request log stream
+- Container health status
+- Resource utilization
+
+---
+
+### 6. `cnode_cli.py` - CLI Interface
+
+**Framework:** Click (Python CLI framework)
+
+**Command Structure:**
+```
+cnode
+├── start [--replicas N] [--port P] [--mode M] [--image I]
+├── stop [--remove-volumes]
+├── status
+├── scale N
+├── logs [--follow] [--tail N]
+├── restart [--replicas N]
+└── cleanup [--force]
+```
+
+**Execution Flow:**
+```python
+@cli.command("start")
+def start_cmd(replicas, mode, port, env_file, image):
+    manager = ServerManager()
+    result = anyio.run(manager.start(...))  # Async bridge
+    if result["success"]:
+        console.print(success_panel)
+```
+
+**User Feedback:**
+- Rich library for colors/tables
+- Progress spinners during operations
+- Error messages with hints
+- Status tables with health indicators
+
+**State Persistence:**
+- Saves deployment config to `~/.crawl4ai/server_state.yml`
+- Enables stateless commands (status, scale, restart)
+
+---
+
+### 7. Docker Orchestration Details
+
+**Single Container Mode (N=1):**
+```bash
+docker run -d \
+  --name crawl4ai-server \
+  --network crawl4ai-network \
+  -p 11235:11235 \
+  -v crawl4ai-redis-data:/data \
+  unclecode/crawl4ai:latest
+```
+
+**Docker Swarm Mode (N>1, Swarm available):**
+```yaml
+# docker-compose.swarm.yml
+version: '3.8'
+services:
+  crawl4ai:
+    image: unclecode/crawl4ai:latest
+    deploy:
+      replicas: 5
+      update_config:
+        parallelism: 2
+        delay: 10s
+      restart_policy:
+        condition: on-failure
+    ports:
+      - "11235:11235"
+    networks:
+      - crawl4ai-network
+```
+
+Deploy: `docker stack deploy -c docker-compose.swarm.yml crawl4ai-stack`
+
+**Docker Compose + Nginx Mode (N>1, fallback):**
+```yaml
+# docker-compose.yml
+services:
+  crawl4ai-1:
+    image: unclecode/crawl4ai:latest
+    networks: [crawl4ai-network]
+
+  crawl4ai-2:
+    image: unclecode/crawl4ai:latest
+    networks: [crawl4ai-network]
+
+  nginx:
+    image: nginx:alpine
+    ports: ["11235:80"]
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf
+    networks: [crawl4ai-network]
+```
+
+Nginx config (round-robin load balancing):
+```nginx
+upstream crawl4ai_backend {
+    server crawl4ai-1:11235;
+    server crawl4ai-2:11235;
+    server crawl4ai-3:11235;
+}
+
+server {
+    listen 80;
+    location / {
+        proxy_pass http://crawl4ai_backend;
+        proxy_set_header Host $host;
+    }
+}
+```
+
+---
+
+## Memory Leak Prevention Strategy
+
+### Problem Areas & Solutions
+
+**1. Browser Instances**
+```python
+# ❌ BAD - Leak risk
+crawler = AsyncWebCrawler()
+result = await crawler.arun(url)
+# Browser never closed!
+
+# ✅ GOOD - Guaranteed cleanup
+async with AsyncWebCrawler() as crawler:
+    result = await crawler.arun(url)
+    # Auto-closed on exit
+```
+
+**2. WebSocket Connections**
+```python
+# monitor_routes.py
+active_connections = set()
+
+@app.websocket("/monitor/ws")
+async def websocket_endpoint(websocket):
+    await websocket.accept()
+    active_connections.add(websocket)
+    try:
+        while True:
+            await websocket.send_json(get_metrics())
+    finally:
+        active_connections.remove(websocket)  # Critical!
+```
+
+**3. Redis Connections**
+```python
+# Use connection pooling
+redis_pool = aioredis.ConnectionPool(
+    host="localhost",
+    port=6379,
+    max_connections=10,
+    decode_responses=True
+)
+
+# Reuse connections
+async def get_job(job_id):
+    async with redis_pool.get_connection() as conn:
+        data = await conn.get(f"job:{job_id}")
+    # Connection auto-returned to pool
+```
+
+**4. Async Task Cleanup**
+```python
+# Track background tasks
+background_tasks = set()
+
+async def crawl_task(url):
+    try:
+        result = await crawl(url)
+    finally:
+        background_tasks.discard(asyncio.current_task())
+
+# On shutdown
+async def shutdown():
+    tasks = list(background_tasks)
+    for task in tasks:
+        task.cancel()
+    await asyncio.gather(*tasks, return_exceptions=True)
+```
+
+**5. File Descriptor Leaks**
+```python
+# Use context managers for files
+async def save_screenshot(url):
+    async with aiofiles.open(f"{job_id}.png", "wb") as f:
+        await f.write(screenshot_bytes)
+    # File auto-closed
+```
+

+
+## Installation & Distribution
+
+### User Installation Flow
+
+**Script:** `deploy/installer/install-cnode.sh`
+
+**Steps:**
+1. Check Python 3.8+ exists
+2. Check pip available
+3. Check Docker installed (warn if missing)
+4. Create temp dir: `mktemp -d`
+5. Git sparse-checkout:
+   ```bash
+   git init
+   git remote add origin https://github.com/unclecode/crawl4ai.git
+   git config core.sparseCheckout true
+   echo "deploy/installer/cnode_pkg/*" > .git/info/sparse-checkout
+   git pull --depth=1 origin main
+   ```
+6. Install deps: `pip install click rich anyio pyyaml`
+7. Copy package: `cnode_pkg/ → /usr/local/lib/cnode/`
+8. Create wrapper: `/usr/local/bin/cnode`
+   ```bash
+   #!/usr/bin/env bash
+   export PYTHONPATH="/usr/local/lib/cnode:$PYTHONPATH"
+   exec python3 -m cnode_pkg.cli "$@"
+   ```
+9. Cleanup temp dir
+
+**Result:**
+- Binary-like experience (fast startup: ~0.1s)
+- No need for PyInstaller (49x faster)
+- Platform-independent (any OS with Python)
+
+---
+
+## Development Workflow
+
+### Source Code Sync (Auto)
+
+**Git Hook:** `.githooks/pre-commit`
+
+**Trigger:** When committing `deploy/docker/cnode_cli.py` or `server_manager.py`
+
+**Action:**
+```bash
+1. Diff source vs package
+2. If different:
+   - Run sync-cnode.sh
+   - Copy cnode_cli.py → cnode_pkg/cli.py
+   - Fix imports: s/deploy.docker/cnode_pkg/g
+   - Copy server_manager.py → cnode_pkg/
+   - Stage synced files
+3. Continue commit
+```
+
+**Setup:** `./setup-hooks.sh` (configures `git config core.hooksPath .githooks`)
+
+**Smart Behavior:**
+- Silent when no sync needed
+- Only syncs if content differs
+- Minimal output: `✓ cnode synced`
+
+---
+
+## API Request/Response Flow
+
+### Example: POST /crawl
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "browser_config": {

+      "type": "CrawlerRunConfig",
+      "params": {"cache_mode": "bypass"}
+    }
+  }'
+```

+1. FastAPI receives request → api.py:crawl_endpoint()
+2. Validate schema → Pydantic models in schemas.py
+3. Create job → job.py:Job(id=uuid4(), urls=[...])
+4. Queue to Redis → LPUSH crawl_queue {job_json}
+5. Get browser from pool → crawler_pool.py:get_crawler()
+6. Execute crawl:
+   a. Launch page → browser.new_page()
+   b. Navigate → page.goto(url)
+   c. Extract → extraction_strategy.extract()
+   d. Generate markdown → markdown_generator.generate()
+7. Store result → Redis SETEX result:{job_id} 3600 {result_json}
+8. Release browser → pool.release(browser_id)
+9. Return response:
+   {
+     "success": true,
+     "result": {
+       "url": "https://example.com",
+       "markdown": "# Example Domain...",
+       "metadata": {"title": "Example Domain"},
+       "extracted_content": {...}
+     }
+   }
+```
+
+**Error Cases:**
+- 400: Invalid request schema
+- 429: Rate limit exceeded
+- 500: Internal error (browser crash, timeout)
+- 503: Service unavailable (all browsers busy)

+
+## Scaling Behavior
+
+### Scale-Up (1 → 10 replicas)
+
+**Command:** `cnode scale 10`
+
+**Swarm Mode:**
+```bash
+docker service scale crawl4ai-stack_crawl4ai=10
+# Docker handles:
+# - Container creation
+# - Network attachment
+# - Load balancer update
+# - Rolling deployment
+```
+
+**Compose Mode:**
+```bash
+# Update docker-compose.yml
+# Change replica count in all service definitions
+docker-compose up -d --scale crawl4ai=10
+# Regenerate nginx.conf with 10 upstreams
+docker exec nginx nginx -s reload
+```
+
+**Load Distribution:**
+- Swarm: Built-in ingress network (VIP-based round-robin)
+- Compose: Nginx upstream (round-robin, can configure least_conn)
+
+**Zero-Downtime:**
+- Swarm: Yes (rolling update, parallelism=2)
+- Compose: Partial (nginx reload is graceful, but brief spike)

+### Asynchronous Jobs with Webhooks
+
+For long-running crawls or when you want to avoid keeping connections open, use the job queue endpoints. Instead of polling for results, configure a webhook to receive notifications when jobs complete.
+
+#### Why Use Jobs & Webhooks?
+
+- **No Polling Required** - Get notified when crawls complete instead of constantly checking status
+- **Better Resource Usage** - Free up client connections while jobs run in the background
+- **Scalable Architecture** - Ideal for high-volume crawling with TypeScript/Node.js clients or microservices
+- **Reliable Delivery** - Automatic retry with exponential backoff (5 attempts: 1s → 2s → 4s → 8s → 16s)
+
+#### How It Works
+
+1. **Submit Job** → POST to `/crawl/job` with optional `webhook_config`
+2. **Get Task ID** → Receive a `task_id` immediately
+3. **Job Runs** → Crawl executes in the background
+4. **Webhook Fired** → Server POSTs completion notification to your webhook URL
+5. **Fetch Results** → If data wasn't included in webhook, GET `/crawl/job/{task_id}`
+
+#### Quick Example
+
+```bash
+# Submit a crawl job with webhook notification
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false
+    }
+  }'
+
+# Response: {"task_id": "crawl_a1b2c3d4"}
+```
+
+**Your webhook receives:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"]
+}
+```
+
+Then fetch the results:
+```bash
+curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
+```
+
+#### Include Data in Webhook
+
+Set `webhook_data_in_payload: true` to receive the full crawl results directly in the webhook:
+
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Your webhook receives the complete data:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "data": {
+    "markdown": "...",
+    "html": "...",
+    "links": {...},
+    "metadata": {...}
+  }
+}
+```
+
+#### Webhook Authentication
+
+Add custom headers for authentication:
+
+```json
+{
+  "urls": ["https://example.com"],
+  "webhook_config": {
+    "webhook_url": "https://myapp.com/webhooks/crawl",
+    "webhook_data_in_payload": false,
+    "webhook_headers": {
+      "X-Webhook-Secret": "your-secret-token",
+      "X-Service-ID": "crawl4ai-prod"
+    }
+  }
+}
+```
+
+#### Global Default Webhook
+
+Configure a default webhook URL in `config.yml` for all jobs:
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"
+  data_in_payload: false
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000
+    max_delay_ms: 32000
+    timeout_ms: 30000
+```
+
+Now jobs without `webhook_config` automatically use the default webhook.
+
+#### Job Status Polling (Without Webhooks)
+
+If you prefer polling instead of webhooks, just omit `webhook_config`:
+
+```bash
+# Submit job
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{"urls": ["https://example.com"]}'
+# Response: {"task_id": "crawl_xyz"}
+
+# Poll for status
+curl http://localhost:11235/crawl/job/crawl_xyz
+```
+
+The response includes `status` field: `"processing"`, `"completed"`, or `"failed"`.
+
+#### LLM Extraction Jobs with Webhooks
+
+The same webhook system works for LLM extraction jobs via `/llm/job`:
+
+```bash
+# Submit LLM extraction job with webhook
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and main points",
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true,
+      "webhook_headers": {
+        "X-Webhook-Secret": "your-secret-token"
+      }
+    }
+  }'
+
+# Response: {"task_id": "llm_1234567890"}
+```
+
+**Your webhook receives:**
+```json
+{
+  "task_id": "llm_1234567890",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-22T12:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "main_points": ["Point 1", "Point 2", "Point 3"]
+    }
+  }
+}
+```
+
+**Key Differences for LLM Jobs:**
+- Task type is `"llm_extraction"` instead of `"crawl"`
+- Extracted data is in `data.extracted_content`
+- Single URL only (not an array)
+- Supports schema-based extraction with `schema` parameter
+
+> 💡 **Pro tip**: See [WEBHOOK_EXAMPLES.md](./WEBHOOK_EXAMPLES.md) for detailed examples including TypeScript client code, Flask webhook handlers, and failure handling.

+# Webhook Feature Examples
+
+This document provides examples of how to use the webhook feature for crawl jobs in Crawl4AI.
+
+## Overview
+
+The webhook feature allows you to receive notifications when crawl jobs complete, eliminating the need for polling. Webhooks are sent with exponential backoff retry logic to ensure reliable delivery.
+
+## Configuration
+
+### Global Configuration (config.yml)
+
+You can configure default webhook settings in `config.yml`:
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: null  # Optional: default webhook URL for all jobs
+  data_in_payload: false  # Optional: default behavior for including data
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000  # 1s, 2s, 4s, 8s, 16s exponential backoff
+    max_delay_ms: 32000
+    timeout_ms: 30000  # 30s timeout per webhook call
+  headers:  # Optional: default headers to include
+    User-Agent: "Crawl4AI-Webhook/1.0"
+```
+
+## API Usage Examples
+
+### Example 1: Basic Webhook (Notification Only)
+
+Send a webhook notification without including the crawl data in the payload.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false
+    }
+  }'
+```
+
+**Response:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4"
+}
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"]
+}
+```
+
+Your webhook handler should then fetch the results:
+```bash
+curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
+```
+
+### Example 2: Webhook with Data Included
+
+Include the full crawl results in the webhook payload.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "data": {
+    "markdown": "...",
+    "html": "...",
+    "links": {...},
+    "metadata": {...}
+  }
+}
+```
+
+### Example 3: Webhook with Custom Headers
+
+Include custom headers for authentication or identification.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false,
+      "webhook_headers": {
+        "X-Webhook-Secret": "my-secret-token",
+        "X-Service-ID": "crawl4ai-production"
+      }
+    }
+  }'
+```
+
+The webhook will be sent with these additional headers plus the default headers from config.
+
+### Example 4: Failure Notification
+
+When a crawl job fails, a webhook is sent with error details.
+
+**Webhook Payload on Failure:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "failed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "error": "Connection timeout after 30s"
+}
+```
+
+### Example 5: Using Global Default Webhook
+
+If you set a `default_url` in config.yml, jobs without webhook_config will use it:
+
+**config.yml:**
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"
+  data_in_payload: false
+```
+
+**Request (no webhook_config needed):**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"]
+  }'
+```
+
+The webhook will be sent to the default URL configured in config.yml.
+
+### Example 6: LLM Extraction Job with Webhook
+
+Use webhooks with the LLM extraction endpoint for asynchronous processing.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and publication date",
+    "schema": "{\"type\": \"object\", \"properties\": {\"title\": {\"type\": \"string\"}, \"author\": {\"type\": \"string\"}, \"date\": {\"type\": \"string\"}}}",

+
+## Webhook Handler Example
+
+Here's a simple Python Flask webhook handler that supports both crawl and LLM extraction jobs:
+
+```python
+from flask import Flask, request, jsonify
+import requests
+
+app = Flask(__name__)
+
+@app.route('/webhooks/crawl-complete', methods=['POST'])
+def handle_crawl_webhook():
+    payload = request.json
+
+    task_id = payload['task_id']
+    task_type = payload['task_type']
+    status = payload['status']
+
+    if status == 'completed':
+        # If data not in payload, fetch it
+        if 'data' not in payload:
+            # Determine endpoint based on task type
+            endpoint = 'crawl' if task_type == 'crawl' else 'llm'
+            response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
+            data = response.json()
+        else:
+            data = payload['data']
+
+        # Process based on task type
+        if task_type == 'crawl':
+            print(f"Processing crawl results for {task_id}")
+            # Handle crawl results
+            results = data.get('results', [])
+            for result in results:
+                print(f"  - {result.get('url')}: {len(result.get('markdown', ''))} chars")
+
+        elif task_type == 'llm_extraction':
+            print(f"Processing LLM extraction for {task_id}")
+            # Handle LLM extraction
+            # Note: Webhook sends 'extracted_content', API returns 'result'
+            extracted = data.get('extracted_content', data.get('result', {}))
+            print(f"  - Extracted: {extracted}")
+
+        # Your business logic here...
+
+    elif status == 'failed':
+        error = payload.get('error', 'Unknown error')
+        print(f"{task_type} job {task_id} failed: {error}")
+        # Handle failure...
+
+    return jsonify({"status": "received"}), 200
+
+if __name__ == '__main__':
+    app.run(port=8080)
+```
+
+## Retry Logic
+
+The webhook delivery service uses exponential backoff retry logic:
+
+- **Attempts:** Up to 5 attempts by default
+- **Delays:** 1s → 2s → 4s → 8s → 16s
+- **Timeout:** 30 seconds per attempt
+- **Retry Conditions:**
+  - Server errors (5xx status codes)
+  - Network errors
+  - Timeouts
+- **No Retry:**
+  - Client errors (4xx status codes)
+  - Successful delivery (2xx status codes)
+
+## Benefits
+
+1. **No Polling Required** - Eliminates constant API calls to check job status
+2. **Real-time Notifications** - Immediate notification when jobs complete
+3. **Reliable Delivery** - Exponential backoff ensures webhooks are delivered
+4. **Flexible** - Choose between notification-only or full data delivery
+5. **Secure** - Support for custom headers for authentication
+6. **Configurable** - Global defaults or per-job configuration
+7. **Universal Support** - Works with both `/crawl/job` and `/llm/job` endpoints
+
+## TypeScript Client Example
+
+```typescript
+interface WebhookConfig {
+  webhook_url: string;
+  webhook_data_in_payload?: boolean;
+  webhook_headers?: Record<string, string>;
+}
+
+interface CrawlJobRequest {
+  urls: string[];
+  browser_config?: Record<string, any>;
+  crawler_config?: Record<string, any>;
+  webhook_config?: WebhookConfig;
+}
+
+interface LLMJobRequest {
+  url: string;
+  q: string;
+  schema?: string;
+  cache?: boolean;
+  provider?: string;
+  webhook_config?: WebhookConfig;
+}
+
+async function createCrawlJob(request: CrawlJobRequest) {
+  const response = await fetch('http://localhost:11235/crawl/job', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify(request)
+  });
+
+  const { task_id } = await response.json();
+  return task_id;
+}
+
+async function createLLMJob(request: LLMJobRequest) {
+  const response = await fetch('http://localhost:11235/llm/job', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify(request)
+  });
+
+  const { task_id } = await response.json();
+  return task_id;
+}
+
+// Usage - Crawl Job
+const crawlTaskId = await createCrawlJob({
+  urls: ['https://example.com'],
+  webhook_config: {
+    webhook_url: 'https://myapp.com/webhooks/crawl-complete',
+    webhook_data_in_payload: false,
+    webhook_headers: {
+      'X-Webhook-Secret': 'my-secret'
+    }
+  }
+});
+
+// Usage - LLM Extraction Job
+const llmTaskId = await createLLMJob({
+  url: 'https://example.com/article',
+  q: 'Extract the main points from this article',
+  provider: 'openai/gpt-4o-mini',
+  webhook_config: {
+    webhook_url: 'https://myapp.com/webhooks/llm-complete',
+    webhook_data_in_payload: true,
+    webhook_headers: {
+      'X-Webhook-Secret': 'my-secret'
+    }
+  }
+});
+```
+
+## Monitoring and Debugging
+
+Webhook delivery attempts are logged at INFO level:
+- Successful deliveries
+- Retry attempts with delays
+- Final failures after max attempts
+
+Check the application logs for webhook delivery status:
+```bash
+docker logs crawl4ai-container | grep -i webhook
+```

+# Crawl4AI 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

+
+## Test Execution Workflow
+
+Each test follows this pattern:
+
+1. **Setup:** Clean state, activate venv
+2. **Execute:** Run test commands
+3. **Verify:** Check results and assertions
+4. **Cleanup:** Stop server, remove resources
+
+## Running Individual Tests
+
+```bash
+# Make test executable (if needed)
+chmod +x deploy/docker/tests/cli/basic/test_01_start_default.sh
+
+# Run directly
+./deploy/docker/tests/cli/basic/test_01_start_default.sh
+
+# Or use the test runner
+./run_tests.sh basic 01
+```
+
+## Interpreting Results
+
+### Success Output
+```
+✅ Test passed: [description]
+```
+
+### Failure Output
+```
+❌ Test failed: [error message]
+```
+
+### Warning Output
+```
+⚠️  Warning: [issue description]
+```
+
+## Common Issues
+
+### Docker Not Running
+```
+Error: Docker daemon not running
+Solution: Start Docker Desktop or Docker daemon
+```
+
+### Port Already In Use
+```
+Error: Port 11235 is already in use
+Solution: Stop existing server or use different port
+```
+
+### Virtual Environment Not Found
+```
+Warning: venv not found
+Solution: Create venv and activate it
+```
+
+### Playwright Not Installed
+```
+Error: playwright module not found
+Solution: pip install playwright && playwright install chromium
+```
+
+## Test Development
+
+### Adding New Tests
+
+1. **Choose category:** basic, advanced, resource, dashboard, or edge
+2. **Create test file:** Follow naming pattern `test_XX_description.sh`
+3. **Use template:**
+
+```bash
+#!/bin/bash
+# Test: [Description]
+# Expected: [What should happen]
+
+set -e
+
+echo "=== Test: [Name] ==="
+echo ""
+
+source venv/bin/activate
+
+# Cleanup
+crwl server stop 2>/dev/null || true
+sleep 2
+
+# Test logic here
+
+# Cleanup
+crwl server stop >/dev/null 2>&1
+
+echo ""
+echo "✅ Test passed: [success message]"
+```
+
+4. **Make executable:** `chmod +x test_XX_description.sh`
+5. **Test it:** `./test_XX_description.sh`
+6. **Add to runner:** Tests are auto-discovered by `run_tests.sh`
+
+## CI/CD Integration
+
+These tests can be integrated into CI/CD pipelines:
+
+```yaml
+# Example GitHub Actions
+- name: Run CLI Tests
+  run: |
+    source venv/bin/activate
+    cd deploy/docker/tests/cli
+    ./run_tests.sh all
+```
+
+## Performance Considerations
+
+- **Basic tests:** ~2-5 minutes total
+- **Advanced tests:** ~5-10 minutes total
+- **Resource tests:** ~10-15 minutes total (including 5-min stability test)
+- **Dashboard test:** ~3-5 minutes
+- **Edge case tests:** ~5-8 minutes total
+
+**Full suite:** ~30-45 minutes
+
+## Best Practices
+
+1. **Always cleanup:** Each test should cleanup after itself
+2. **Wait for readiness:** Add sleep after starting servers
+3. **Check health:** Verify health endpoint before assertions
+4. **Graceful failures:** Use `|| true` to continue on expected failures
+5. **Clear messages:** Output should clearly indicate what's being tested
+
+## Troubleshooting
+
+### Tests Hanging
+- Check if Docker containers are stuck
+- Look for port conflicts
+- Verify network connectivity
+
+### Intermittent Failures
+- Increase sleep durations for slower systems
+- Check system resources (memory, CPU)
+- Verify Docker has enough resources allocated
+
+### All Tests Failing
+- Verify Docker is running: `docker ps`
+- Check CLI is installed: `which crwl`
+- Activate venv: `source venv/bin/activate`
+- Check server manager: `crwl server status`
+
+## Contributing
+
+When adding new tests:
+1. Follow existing naming conventions
+2. Add comprehensive documentation
+3. Test on clean system
+4. Update this README
+5. Ensure cleanup is robust

+# Crawl4AI Node Manager (cnode) - Installation & Distribution
+
+This directory contains the standalone `cnode` package and installation scripts for managing Crawl4AI Docker server instances.
+
+## Overview
+
+`cnode` is a fast, lightweight CLI tool for managing Crawl4AI Docker servers. It provides:
+- One-command deployment with automatic scaling
+- Single container for development (N=1)
+- Docker Swarm for production with built-in load balancing (N>1)
+- Docker Compose + Nginx as fallback (N>1)
+
+## Directory Structure

+└── releases/                 # Release artifacts for distribution
+```
+
+## Installation
+
+### For Users (Remote Installation)
+
+Users can install `cnode` directly from the web:
+
+```bash
+# Install from GitHub/website
+curl -sSL https://crawl4ai.com/install-cnode.sh | bash
+
+# Or with wget
+wget -qO- https://crawl4ai.com/install-cnode.sh | bash
+```
+
+### For Local Testing
+
+Test the installation locally:
+
+```bash
+cd deploy/installer
+./install-cnode.sh
+```
+
+## Package Contents
+
+### `cnode_pkg/` - Python Package
+
+This is a self-contained Python package with:
+
+- **`cli.py`**: Click-based CLI with all commands (start, stop, status, scale, logs, cleanup, restart)
+- **`server_manager.py`**: Core Docker orchestration logic
+- **`requirements.txt`**: Dependencies (click, rich, anyio, pyyaml)
+- **`__init__.py`**: Package initialization
+
+### Installation Script
+
+**`install-cnode.sh`** does the following:
+1. Checks for Python 3.8+ and pip
+2. Checks for Docker (warns if not found)
+3. Installs Python dependencies
+4. Copies `cnode_pkg/` to `/usr/local/lib/cnode/`
+5. Creates wrapper script at `/usr/local/bin/cnode`
+6. Verifies installation
+
+### Wrapper Script
+
+Created at `/usr/local/bin/cnode`:
+
+```bash
+#!/usr/bin/env bash
+set -e
+
+# Find Python
+if command -v python3 &> /dev/null; then
+    PYTHON_CMD="python3"
+elif command -v python &> /dev/null; then
+    PYTHON_CMD="python"
+else
+    echo "Error: Python 3.8+ required" >&2
+    exit 1
+fi
+
+# Run cnode
+export PYTHONPATH="/usr/local/lib/cnode:$PYTHONPATH"
+exec $PYTHON_CMD -m cnode_pkg.cli "$@"
+```
+
+## Performance
+
+**Blazing Fast Startup:**
+- **~0.1 seconds** to launch
+- 49x faster than compiled binary alternatives
+- Minimal overhead, maximum responsiveness
+
+## Requirements
+
+### User Requirements
+- Python 3.8 or higher
+- pip (Python package manager)
+- Docker (for running servers)
+
+### Dependencies (Auto-installed)
+- click >= 8.0.0 (CLI framework)
+- rich >= 13.0.0 (Terminal formatting)
+- anyio >= 3.0.0 (Async I/O)
+- pyyaml >= 6.0.0 (YAML parsing)
+
+## Usage
+
+After installation:
+
+```bash
+# Quick start
+cnode start                    # Single container on port 11235
+cnode start --replicas 5       # 5-replica cluster
+cnode status                   # Check server status
+cnode logs -f                  # Follow logs
+cnode scale 10                 # Scale to 10 replicas
+cnode stop                     # Stop server
+
+# Get help
+cnode --help
+cnode start --help
+```
+
+## Development Workflow
+
+### Making Changes
+
+1. **Edit source code** in `deploy/docker/`:
+   ```bash
+   vim deploy/docker/cnode_cli.py
+   vim deploy/docker/server_manager.py
+   ```
+
+2. **Update package** by copying to installer:
+   ```bash
+   # Copy CLI
+   cp deploy/docker/cnode_cli.py deploy/installer/cnode_pkg/cli.py
+
+   # Fix imports (deploy.docker → cnode_pkg)
+   sed -i 's/from deploy\.docker\./from cnode_pkg./g' deploy/installer/cnode_pkg/cli.py
+
+   # Copy server manager
+   cp deploy/docker/server_manager.py deploy/installer/cnode_pkg/server_manager.py
+   ```
+
+3. **Test locally**:
+   ```bash
+   cd deploy/installer
+   ./install-cnode.sh
+   cnode --help
+   ```
+
+4. **Commit both**:
+   ```bash
+   git add deploy/docker/cnode_cli.py
+   git add deploy/installer/cnode_pkg/cli.py
+   git commit -m "Update cnode: [description]"
+   ```
+
+### Creating a Release
+
+1. **Tag the release**:
+   ```bash
+   git tag -a v1.0.0 -m "Release v1.0.0"
+   git push origin v1.0.0
+   ```
+
+2. **Package for distribution**:
+   ```bash
+   cd deploy/installer
+   tar -czf releases/cnode-v1.0.0.tar.gz cnode_pkg/ install-cnode.sh
+   ```
+
+3. **Create GitHub release**:
+   ```bash
+   gh release create v1.0.0 \
+     releases/cnode-v1.0.0.tar.gz \
+     --title "cnode v1.0.0" \
+     --notes "Release notes here"
+   ```
+
+4. **Update deployment script** (if needed):
+   - Update `install-cnode.sh` with new version/URL
+   - Upload to hosting (e.g., `https://crawl4ai.com/install-cnode.sh`)
+
+## Deployment
+
+### Remote Installation Script
+
+The `install-cnode.sh` script is meant to be hosted at a public URL for user installation:
+
+```bash
+# Upload to your server
+scp install-cnode.sh user@crawl4ai.com:/var/www/html/install-cnode.sh
+
+# Or use GitHub raw URL
+https://raw.githubusercontent.com/unclecode/crawl4ai/main/deploy/installer/install-cnode.sh
+```
+
+Users can then install with:
+```bash
+curl -sSL https://crawl4ai.com/install-cnode.sh | bash
+```
+
+## Backward Compatibility
+
+The main Crawl4AI CLI (`crwl`) includes a redirect for backward compatibility:
+
+```bash
+# These work identically:
+crwl server start --replicas 3
+cnode start --replicas 3
+
+# All subcommands redirect:
+crwl server status  → cnode status
+crwl server stop    → cnode stop
+crwl server scale 5 → cnode scale 5
+crwl server logs -f → cnode logs -f
+```
+
+This ensures existing scripts continue working while users migrate to `cnode`.
+
+## Uninstallation
+
+To remove cnode:
+
+```bash
+# Remove command
+sudo rm /usr/local/bin/cnode
+
+# Remove package
+sudo rm -rf /usr/local/lib/cnode
+
+# (Optional) Uninstall dependencies
+pip uninstall click rich anyio pyyaml
+```
+
+## Troubleshooting
+
+### Python Not Found
+```bash
+# Install Python 3.8+
+# macOS: brew install python3
+# Ubuntu: sudo apt install python3 python3-pip
+# RHEL/CentOS: sudo yum install python3 python3-pip
+```
+
+### Permission Denied
+```bash
+# Run installer with sudo
+sudo ./install-cnode.sh
+
+# Or change install location
+INSTALL_DIR=$HOME/.local/bin ./install-cnode.sh
+```
+
+### Command Not Found After Install
+```bash
+# Add to PATH in ~/.bashrc or ~/.zshrc
+export PATH="/usr/local/bin:$PATH"
+
+# Reload shell
+source ~/.bashrc  # or source ~/.zshrc
+```
+
+### Dependencies Install Failed
+```bash
+# Install manually
+pip install --user click rich anyio pyyaml
+
+# Or with break-system-packages (if needed)
+pip install --user --break-system-packages click rich anyio pyyaml
+```
+
+### Docker Not Running
+```bash
+# macOS: Start Docker Desktop
+# Linux: sudo systemctl start docker
+
+# Check Docker
+docker --version
+docker ps
+```
+
+## Architecture
+
+### Component Flow
+
+```
+User runs: cnode start
+         ↓
+/usr/local/bin/cnode (wrapper script)
+         ↓
+Finds python3 executable
+         ↓
+Sets PYTHONPATH=/usr/local/lib/cnode
+         ↓
+python3 -m cnode_pkg.cli start
+         ↓
+cli.py → start_cmd()
+         ↓
+server_manager.py → ServerManager.start()
+         ↓
+Docker orchestration (single/swarm/compose)
+         ↓
+Server running!
+```
+
+### Why Python Wrapper vs Binary?
+
+We chose a Python wrapper over compiled binaries (PyInstaller) because:
+
+| Metric | Python Wrapper | PyInstaller Binary |
+|--------|---------------|-------------------|
+| Startup time | **0.1s** | 4.7s |
+| Size | ~50KB wrapper | 8.8MB |
+| Updates | Easy (just copy files) | Rebuild required |
+| Dependencies | Python 3.8+ | None |
+| Platform | Any with Python | OS-specific builds |
+
+Since users running Crawl4AI already have Python, the wrapper is the clear winner.

+
+## Troubleshooting
+
+### Server Won't Start
+
+```bash
+# Check Docker is running
+docker ps
+
+# Check port availability
+lsof -i :11235
+
+# Check logs for errors
+cnode logs
+```
+
+### High Memory Usage
+
+```bash
+# Check current status
+cnode status
+
+# Restart to clear memory
+cnode restart
+
+# Scale down if needed
+cnode scale 2
+```
+
+### Slow Response Times
+
+```bash
+# Scale up for better performance
+cnode scale 10
+
+# Check system resources
+docker stats
+```
+
+### Cannot Connect to API
+
+```bash
+# Verify server is running
+cnode status
+
+# Check firewall
+sudo ufw status
+
+# Test locally
+curl http://localhost:11235/health
+```
+
+### Clean Slate
+
+```bash
+# Complete cleanup and restart
+cnode cleanup --force
+cnode start --replicas 5
+```
+
+---
+
+## Advanced Topics
+
+### Environment Variables
+
+Create `.env` file for API keys:
+
+```bash
+# .env file
+OPENAI_API_KEY=sk-your-key
+ANTHROPIC_API_KEY=your-key
+```
+
+Use with cnode:
+```bash
+cnode start --env-file .env --replicas 3
+```
+
+### Custom Docker Image
+
+```bash
+# Use specific version
+cnode start --image unclecode/crawl4ai:0.7.0-r1
+
+# Use custom registry
+cnode start --image myregistry.com/crawl4ai:custom
+```
+
+### Production Best Practices
+
+1. **Use Multiple Replicas**
+   ```bash
+   cnode start --replicas 5
+   ```
+
+2. **Monitor Regularly**
+   ```bash
+   # Set up monitoring cron
+   */5 * * * * cnode status | mail -s "Crawl4AI Status" admin@example.com
+   ```
+
+3. **Regular Log Rotation**
+   ```bash
+   cnode logs --tail 1000 > crawl4ai.log
+   cnode restart
+   ```
+
+4. **Resource Limits**
+   - Ensure adequate RAM (2GB per replica minimum)
+   - Monitor disk space for cached data
+   - Use SSD for better performance
+
+### Integration Examples
+
+**With Python App:**
+```python
+from crawl4ai.docker_client import Crawl4aiDockerClient

+### Resources
+
+- 📖 [Full Documentation](https://docs.crawl4ai.com)
+- 🐛 [Report Issues](https://github.com/unclecode/crawl4ai/issues)
+- 💬 [Discord Community](https://discord.gg/crawl4ai)
+- 📺 [Video Tutorials](https://youtube.com/@crawl4ai)
+
+### Common Questions
+
+**Q: How many replicas should I use?**
+A: Start with 1 for development. Use 3-5 for production. Scale based on load.
+
+**Q: What's the difference between Swarm and Compose mode?**
+A: Swarm has built-in load balancing (faster). Compose uses Nginx (fallback if Swarm unavailable).
+
+**Q: Can I run multiple cnode instances?**
+A: Yes! Use different ports: `cnode start --port 8080`
+
+**Q: How do I update to the latest version?**
+A: Pull new image: `cnode stop && docker pull unclecode/crawl4ai:latest && cnode start`
+
+---
+
+## Summary
+
+You now know how to:
+- ✅ Install cnode with one command
+- ✅ Start and manage Crawl4AI servers
+- ✅ Scale from 1 to 100+ replicas
+- ✅ Monitor performance in real-time
+- ✅ Use the API from any language
+- ✅ Troubleshoot common issues
+
+**Ready to crawl at scale!** 🚀
+
+For detailed Docker configuration and advanced deployment options, see the [Docker Guide](../docker/README.md).

+# Crawl4AI v0.7.6 Release Notes
+
+*Release Date: October 22, 2025*
+
+I'm excited to announce Crawl4AI v0.7.6, featuring a complete webhook infrastructure for the Docker job queue API! This release eliminates polling and brings real-time notifications to both crawling and LLM extraction workflows.
+
+## 🎯 What's New
+
+### Webhook Support for Docker Job Queue API
+
+The headline feature of v0.7.6 is comprehensive webhook support for asynchronous job processing. No more constant polling to check if your jobs are done - get instant notifications when they complete!
+
+**Key Capabilities:**
+
+- ✅ **Universal Webhook Support**: Both `/crawl/job` and `/llm/job` endpoints now support webhooks
+- ✅ **Flexible Delivery Modes**: Choose notification-only or include full data in the webhook payload
+- ✅ **Reliable Delivery**: Exponential backoff retry mechanism (5 attempts: 1s → 2s → 4s → 8s → 16s)
+- ✅ **Custom Authentication**: Add custom headers for webhook authentication
+- ✅ **Global Configuration**: Set default webhook URL in `config.yml` for all jobs
+- ✅ **Task Type Identification**: Distinguish between `crawl` and `llm_extraction` tasks
+
+### How It Works
+
+Instead of constantly checking job status:
+
+**OLD WAY (Polling):**
+```python
+# Submit job
+response = requests.post("http://localhost:11235/crawl/job", json=payload)
+task_id = response.json()['task_id']
+
+# Poll until complete
+while True:
+    status = requests.get(f"http://localhost:11235/crawl/job/{task_id}")
+    if status.json()['status'] == 'completed':
+        break
+    time.sleep(5)  # Wait and try again
+```
+
+**NEW WAY (Webhooks):**
+```python
+# Submit job with webhook
+payload = {
+    "urls": ["https://example.com"],
+    "webhook_config": {
+        "webhook_url": "https://myapp.com/webhook",
+        "webhook_data_in_payload": True
+    }
+}
+response = requests.post("http://localhost:11235/crawl/job", json=payload)
+
+# Done! Webhook will notify you when complete
+# Your webhook handler receives the results automatically
+```
+
+### Crawl Job Webhooks
+
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "browser_config": {"headless": true},
+    "crawler_config": {"cache_mode": "bypass"},
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false,
+      "webhook_headers": {
+        "X-Webhook-Secret": "your-secret-token"
+      }
+    }
+  }'
+```
+
+### LLM Extraction Job Webhooks (NEW!)
+
+```bash
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and publication date",
+    "schema": "{\"type\":\"object\",\"properties\":{\"title\":{\"type\":\"string\"}}}",
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+### Webhook Payload Structure
+
+**Success (with data):**
+```json
+{
+  "task_id": "llm_1698765432",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-22T10:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "date": "2025-10-22"
+    }
+  }
+}
+```
+
+**Failure:**
+```json
+{
+  "task_id": "crawl_abc123",
+  "task_type": "crawl",
+  "status": "failed",
+  "timestamp": "2025-10-22T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "error": "Connection timeout after 30s"
+}
+```
+
+### Simple Webhook Handler Example
+
+```python
+from flask import Flask, request, jsonify
+
+app = Flask(__name__)
+
+@app.route('/webhook', methods=['POST'])
+def handle_webhook():
+    payload = request.json
+
+    task_id = payload['task_id']
+    task_type = payload['task_type']
+    status = payload['status']
+
+    if status == 'completed':
+        if 'data' in payload:
+            # Process data directly
+            data = payload['data']
+        else:
+            # Fetch from API
+            endpoint = 'crawl' if task_type == 'crawl' else 'llm'
+            response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
+            data = response.json()
+
+        # Your business logic here
+        print(f"Job {task_id} completed!")
+
+    elif status == 'failed':
+        error = payload.get('error', 'Unknown error')
+        print(f"Job {task_id} failed: {error}")
+
+    return jsonify({"status": "received"}), 200
+
+app.run(port=8080)
+```
+
+## 📊 Performance Improvements
+
+- **Reduced Server Load**: Eliminates constant polling requests
+- **Lower Latency**: Instant notification vs. polling interval delay
+- **Better Resource Usage**: Frees up client connections while jobs run in background
+- **Scalable Architecture**: Handles high-volume crawling workflows efficiently
+
+## 🐛 Bug Fixes
+
+- Fixed webhook configuration serialization for Pydantic HttpUrl fields
+- Improved error handling in webhook delivery service
+- Enhanced Redis task storage for webhook config persistence
+
+## 🌍 Expected Real-World Impact
+
+### For Web Scraping Workflows
+- **Reduced Costs**: Less API calls = lower bandwidth and server costs
+- **Better UX**: Instant notifications improve user experience
+- **Scalability**: Handle 100s of concurrent jobs without polling overhead
+
+### For LLM Extraction Pipelines
+- **Async Processing**: Submit LLM extraction jobs and move on
+- **Batch Processing**: Queue multiple extractions, get notified as they complete
+- **Integration**: Easy integration with workflow automation tools (Zapier, n8n, etc.)
+
+### For Microservices
+- **Event-Driven**: Perfect for event-driven microservice architectures
+- **Decoupling**: Decouple job submission from result processing
+- **Reliability**: Automatic retries ensure webhooks are delivered
+
+## 🔄 Breaking Changes
+
+**None!** This release is fully backward compatible.
+
+- Webhook configuration is optional
+- Existing code continues to work without modification
+- Polling is still supported for jobs without webhook config
+
+## 📚 Documentation
+
+### New Documentation
+- **[WEBHOOK_EXAMPLES.md](../deploy/docker/WEBHOOK_EXAMPLES.md)** - Comprehensive webhook usage guide
+- **[docker_webhook_example.py](../docs/examples/docker_webhook_example.py)** - Working code examples
+
+### Updated Documentation
+- **[Docker README](../deploy/docker/README.md)** - Added webhook sections
+- API documentation with webhook examples
+
+## 🛠️ Migration Guide
+
+No migration needed! Webhooks are opt-in:
+
+1. **To use webhooks**: Add `webhook_config` to your job payload
+2. **To keep polling**: Continue using your existing code
+
+### Quick Start
+
+```python
+# Just add webhook_config to your existing payload
+payload = {
+    # Your existing configuration
+    "urls": ["https://example.com"],
+    "browser_config": {...},
+    "crawler_config": {...},
+
+    # NEW: Add webhook configuration
+    "webhook_config": {
+        "webhook_url": "https://myapp.com/webhook",
+        "webhook_data_in_payload": True
+    }
+}
+```
+
+## 🔧 Configuration
+
+### Global Webhook Configuration (config.yml)
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"  # Optional
+  data_in_payload: false
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000
+    max_delay_ms: 32000
+    timeout_ms: 30000
+  headers:
+    User-Agent: "Crawl4AI-Webhook/1.0"
+```
+
+## 🚀 Upgrade Instructions
+
+### Docker
+
+```bash
+# Pull the latest image
+docker pull unclecode/crawl4ai:0.7.6
+
+# Or use latest tag
+docker pull unclecode/crawl4ai:latest
+
+# Run with webhook support
+docker run -d \
+  -p 11235:11235 \
+  --env-file .llm.env \
+  --name crawl4ai \
+  unclecode/crawl4ai:0.7.6
+```
+
+### Python Package
+
+```bash
+pip install --upgrade crawl4ai
+```
+
+## 💡 Pro Tips
+
+1. **Use notification-only mode** for large results - fetch data separately to avoid large webhook payloads
+2. **Set custom headers** for webhook authentication and request tracking
+3. **Configure global default webhook** for consistent handling across all jobs
+4. **Implement idempotent webhook handlers** - same webhook may be delivered multiple times on retry
+5. **Use structured schemas** with LLM extraction for predictable webhook data
+
+## 🎬 Demo
