How it works:

1. Clients (Node.js, Go, Python, etc.) connect via Playwright
2. HTTP API provides endpoints via GET /next (round-robin)
3. Load Balancer distributes connections across browser instances
4. Browser Pool maintains multiple Camoufox instances with unique fingerprints
5. Each client gets a WebSocket endpoint to connect directly to a browser

Why Camoufox Connector?

Camoufox is a powerful anti-detect browser based on Firefox, but its Python-only interface limits accessibility. Camoufox Connector solves this by:

• Exposing WebSocket endpoints that any Playwright client can connect to
• Managing browser pools for high-volume scraping with fingerprint rotation
• Providing health monitoring via HTTP API
• Simplifying deployment with Docker support

Features

• Multi-language support - Connect from Node.js, Go, Python, Java, .NET, or any Playwright-compatible language
• Single & Pool modes - One persistent browser or multiple rotating browsers
• Round-robin load balancing - Distribute connections across browser instances
• Fingerprint rotation - Each browser instance has a unique fingerprint
• Health check API - Monitor browser health and statistics
• Docker ready - Production-ready containerization
• High performance - Async architecture optimized for concurrent connections

Connect from Node.js

import { firefox } from 'playwright';

// Get endpoint from the connector API
const response = await fetch('http://localhost:8080/next');
const { endpoint } = await response.json();

// Connect to Camoufox
const browser = await firefox.connect(endpoint);
const page = await browser.newPage();

await page.goto('https://example.com');
console.log(await page.title());

await browser.close();

Connect from Go

package main

import (
    "github.com/playwright-community/playwright-go"
)

func main() {
    pw, _ := playwright.Run()
    defer pw.Stop()
    
    // Get endpoint from connector API
    // endpoint := getEndpointFromAPI()
    endpoint := "ws://localhost:9222/abc123"
    
    browser, _ := pw.Firefox.Connect(endpoint)
    page, _ := browser.NewPage()
    
    page.Goto("https://example.com")
    title, _ := page.Title()
    println(title)
    
    browser.Close()
}

Connect from Python

import httpx
from playwright.async_api import async_playwright

async def main():
    # Get endpoint from connector API
    async with httpx.AsyncClient() as client:
        response = await client.get("http://localhost:8080/next")
        endpoint = response.json()["endpoint"]
    
    async with async_playwright() as p:
        browser = await p.firefox.connect(endpoint)
        page = await browser.new_page()
        
        await page.goto("https://example.com")
        print(await page.title())
        
        await browser.close()

Operating Modes

Single Mode (Default)

One browser instance with a consistent fingerprint. Ideal for:

• Maintaining logged-in sessions
• Sequential scraping tasks
• Development and testing

camoufox-connector --mode single

Pool Mode

Multiple browser instances with different fingerprints, distributed via round-robin. Ideal for:

• High-volume scraping
• Avoiding detection through fingerprint rotation
• Parallel processing

camoufox-connector --mode pool --pool-size 5

Note: Since each browser instance maintains its own fingerprint, use pool mode when you need fingerprint rotation between requests. Use single mode when you need session persistence.

HTTP API

The connector exposes an HTTP API for health monitoring and browser management.

Endpoint	Method	Description
/	GET	Server info and version
/health	GET	Health check (returns 200/503)
/next	GET	Get next browser endpoint (round-robin)
/endpoints	GET	List all available endpoints
/stats	GET	Pool statistics and connection counts
/restart/{n}	POST	Restart browser instance N

Example API Responses

GET /next

{
  "endpoint": "ws://localhost:9222/abc123def456"
}

GET /health

{
  "status": "healthy",
  "mode": "pool",

    {"index": 0, "healthy": true, "endpoint": "ws://..."},
    {"index": 1, "healthy": true, "endpoint": "ws://..."},
    {"index": 2, "healthy": true, "endpoint": "ws://..."}
  ]
}

GET /stats

Use Cases

High-Volume Web Scraping

// Distribute scraping across multiple fingerprints
async function scrapeUrls(urls) {
  const results = await Promise.all(urls.map(async (url) => {
    // Each request gets a different browser/fingerprint
    const { endpoint } = await fetch('http://localhost:8080/next').then(r => r.json());
    const browser = await firefox.connect(endpoint);
    
    try {
      const page = await browser.newPage();
      await page.goto(url);
      return await page.content();
    } finally {
      await browser.close();
    }
  }));
  
  return results;
}

Session Persistence

// Use a specific endpoint for session persistence
const { endpoints } = await fetch('http://localhost:8080/endpoints').then(r => r.json());
const sessionEndpoint = endpoints[0];  // Always use the same browser

// Login once
let browser = await firefox.connect(sessionEndpoint);
let page = await browser.newPage();
await page.goto('https://example.com/login');
// ... perform login
await browser.close();

// Subsequent requests use the same session
browser = await firefox.connect(sessionEndpoint);
page = await browser.newPage();
await page.goto('https://example.com/dashboard');  // Already logged in

Load Balancing with Health Checks

async function getHealthyEndpoint() {
  const health = await fetch('http://localhost:8080/health').then(r => r.json());
  
  if (health.status !== 'healthy') {
    throw new Error('No healthy browsers available');
  }
  
  const { endpoint } = await fetch('http://localhost:8080/next').then(r => r.json());
  return endpoint;
}

Performance Tips

1. Use pool mode for parallel tasks - Each browser instance can handle multiple pages concurrently
2. Set appropriate pool size - Rule of thumb: 1-2 browsers per CPU core
3. Enable --block-images - Significantly speeds up page loads for text-based scraping
4. Use --headless - Reduces memory and CPU usage
5. Monitor with /stats - Watch connection distribution and adjust pool size accordingly

Troubleshooting

Browser fails to start

# Check if Camoufox is installed with GeoIP support
python -c "from camoufox.sync_api import Camoufox; print('OK')"

# Install with GeoIP support (required for --geoip flag)
pip install camoufox[geoip]
python -m playwright install firefox

GeoIP database error

If you see InvalidDatabaseError: Error opening database file, install camoufox with GeoIP support:

pip install camoufox[geoip]

Or disable GeoIP if you don't need it:

camoufox-connector --no-geoip

Connection refused

# Check if server is running
curl http://localhost:8080/health

# Check if browser WebSocket is accessible
curl -I ws://localhost:9222

Out of memory in Docker

# Increase shared memory (required for browsers)
docker run --shm-size=2gb camoufox-connector
