+# 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": ">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

+        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

-# Proxy 
+# 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.
 
 ## Basic Proxy Setup
 
-Simple proxy configuration with `BrowserConfig`:
+Configure proxies that apply to each crawl operation:
 
 ```python
-from crawl4ai.async_configs import BrowserConfig
+import asyncio
+from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, ProxyConfig
 
-# 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")
+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 SOCKS proxy
-browser_config = BrowserConfig(proxy_config={"server": "socks5://proxy.example.com:1080"})
+
+async def main():
+    browser_config = BrowserConfig()
     async with AsyncWebCrawler(config=browser_config) as crawler:
-    result = await crawler.arun(url="https://example.com")
+        result = await crawler.arun(url="https://example.com", config=run_config)
+        print(f"Success: {result.success} -> {result.url}")
+
+
+if __name__ == "__main__":
+    asyncio.run(main())
 ```
 
-## Authenticated Proxy
+!!! 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.
 
-Use an authenticated proxy with `BrowserConfig`:
+## Supported Proxy Formats
+
+The `ProxyConfig.from_string()` method supports multiple formats:
 
 ```python
-from crawl4ai.async_configs import BrowserConfig
+from crawl4ai import ProxyConfig
 
-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")
+# 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")
 ```
 
+## Authenticated Proxies
+
+For proxies requiring authentication:
+
+```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
 
-Example using a proxy rotation service dynamically:
+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 re
-from crawl4ai import (
-    AsyncWebCrawler,
-    BrowserConfig,
-    CrawlerRunConfig,
-    CacheMode,
-    RoundRobinProxyStrategy,

+
 async def main():
-    # Load proxies and create rotation strategy
+    # Load proxies from environment
     proxies = ProxyConfig.from_env()
-    #eg: export PROXIES="ip1:port1:username1:password1,ip2:port2:username2:password2"
     if not proxies:
-        print("No proxies found in environment. Set PROXIES env variable!")
+        print("No proxies found! Set PROXIES environment variable.")
         return
 
+    # Create rotation strategy
     proxy_strategy = RoundRobinProxyStrategy(proxies)
 
-    # Create configs
+    # Configure per-request with proxy rotation
     browser_config = BrowserConfig(headless=True, verbose=False)
     run_config = CrawlerRunConfig(
         cache_mode=CacheMode.BYPASS,
-        proxy_rotation_strategy=proxy_strategy

     )

         urls = ["https://httpbin.org/ip"] * (len(proxies) * 2)  # Test each proxy twice

-                        if verified:
-                            print(f"✅ Proxy working! IP matches: {current_proxy.ip}")
+                    print(f"✅ Request {i+1}: Proxy {proxy_index+1} -> IP {detected_ip}")
+                    if detected_ip == expected_ip:
+                        print("   🎯 IP matches proxy configuration")
                     else:
-                            print("❌ Proxy failed or IP mismatch!")
-                    print("---")

+## SSL Certificate Analysis

+
+## 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")

+    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",

+        "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.

+Self-hosting Crawl4AI gives you complete control over your web crawling and data extraction pipeline. Unlike cloud-based solutions, you own your data, infrastructure, and destiny.
+
+## Why Self-Host?
+
+- **🔒 Data Privacy**: Your crawled data never leaves your infrastructure
+- **💰 Cost Control**: No per-request pricing - scale within your own resources
+- **🎯 Customization**: Full control over browser configurations, extraction strategies, and performance tuning
+- **📊 Transparency**: Real-time monitoring dashboard shows exactly what's happening
+- **⚡ Performance**: Direct access without API rate limits or geographic restrictions
+- **🛡️ Security**: Keep sensitive data extraction workflows behind your firewall
+- **🔧 Flexibility**: Customize, extend, and integrate with your existing infrastructure
+
+When you self-host, you can scale from a single container to a full browser infrastructure, all while maintaining complete control and visibility.

+## Real-time Monitoring & Operations
 
-Keep an eye on your crawler with these endpoints:
+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.
 
-- `/health` - Quick health check
-- `/metrics` - Detailed Prometheus metrics
-- `/schema` - Full API schema
+### Monitoring Dashboard
 
-Example health check:
+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:
+
+```bash
+curl http://localhost:11235/health
+```
+
+Returns:
+```json
+{
+  "status": "healthy",
+  "version": "0.7.4"
+}
+```
+
