camofox-browser Anti-detection browser server for AI agents, powered by Camoufox
Standing on the mighty shoulders of Camoufox - a Firefox fork with fingerprint spoofing at the C++ level.
The same engine behind Jo — an AI assistant that doesn't need you to babysit it. Runs half on your Mac, half on a dedicated cloud machine that only you use. Available on macOS, Telegram, and WhatsApp. Try the beta free →
git clone https://github.com/jo-inc/camofox-browser && cd camofox-browser
npm install && npm start
# → http://localhost:9377Why
AI agents need to browse the real web. Playwright gets blocked. Headless Chrome gets fingerprinted. Stealth plugins become the fingerprint.
Camoufox patches Firefox at the C++ implementation level - navigator.hardwareConcurrency, WebGL renderers, AudioContext, screen geometry, WebRTC - all spoofed before JavaScript ever sees them. No shims, no wrappers, no tells.
This project wraps that engine in a REST API built for agents: accessibility snapshots instead of bloated HTML, stable element refs for clicking, and search macros for common sites.
Features
- C++ Anti-Detection - bypasses Google, Cloudflare, and most bot detection
- Element Refs - stable
e1,e2,e3identifiers for reliable interaction - Token-Efficient - accessibility snapshots are ~90% smaller than raw HTML
- Runs on Anything - lazy browser launch + idle shutdown keeps memory at ~40MB when idle. Designed to share a box with the rest of your stack — Raspberry Pi, $5 VPS, shared Railway infra.
- Session Isolation - separate cookies/storage per user
- Cookie Import - inject Netscape-format cookie files for authenticated browsing
- Proxy + GeoIP - route traffic through residential proxies with automatic locale/timezone
- Structured Logging - JSON log lines with request IDs for production observability
- YouTube Transcripts - extract captions from any YouTube video via yt-dlp, no API key needed
- Search Macros -
@google_search,@youtube_search,@amazon_search,@reddit_subreddit, and 10 more - Snapshot Screenshots - include a base64 PNG screenshot alongside the accessibility snapshot
- Large Page Handling - automatic snapshot truncation with offset-based pagination
- Download Capture - capture browser downloads and fetch them via API (optional inline base64)
- DOM Image Extraction - list `` src/alt and optionally return inline data URLs
- Deploy Anywhere - Docker, Fly.io, Railway
Optional Dependencies
| Dependency | Purpose | Install |
|---|---|---|
| yt-dlp | YouTube transcript extraction (fast path) | pip install yt-dlp or brew install yt-dlp |
The Docker image includes yt-dlp. For local dev, install it for the /youtube/transcript endpoint. Without it, the endpoint falls back to a slower browser-based method.
Quick Start
Don't lose this
Three weeks from now, you'll want Camofox Browser again. Will you remember where to find it?
Save it to your library and the next time you need Camofox Browser, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.
⚡ Pro tip for geeks: add a-gnt 🤵🏻♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
