Camofox Browser
🚀 Description
jo-inc/camofox-browser — a stealth headless browser for AI agents. If you build agents that browse the web, you hit the wall fast: bot detection blocks them instantly. Camofox makes the agent’s browser invisible.
It’s built on Camoufox, a Firefox fork that spoofs the fingerprint, WebGL, audio, and WebRTC signatures down at the C++ level — so the browser doesn’t look modified because it genuinely isn’t (no detectable JS patches).
The part agents love: it returns the page as an accessibility tree instead of raw HTML, which drops token cost by ~90%. Drop-in replacement for Puppeteer/Playwright.
🧩 Features
- C++-level stealth —
navigator.hardwareConcurrency, WebGL renderer, AudioContext, screen geometry, WebRTC all spoofed before JavaScript sees them. - Accessibility-tree output — structured page representation, stable element refs for clicking, ~90% fewer tokens than bloated HTML.
- Agent-shaped API — navigate, click, type, screenshot; search macros for common sites.
- Bypasses Cloudflare / anti-scraping / bot detection without paid stealth-scraping services that bill per request.
Reasoning for
The browsing layer for agentic web automation — the same slot as Browser Use and Browser Harness in this vault, but with stealth as the headline and accessibility-tree token savings as the kicker. Pairs with Bright Data / Firecrawl thinking on data acquisition, except this is the headful-but-invisible end where bot walls are the blocker. The ~90% token reduction overlaps in spirit with Headroom — both make agent context cheaper, at different layers.
Alternatives considered
- CloakBrowser — the Chromium counterpart: same C++-level source patches, but keeps the native Playwright/Puppeteer API and adds
humanizebehavioral spoofing (vs Camofox’s accessibility-tree token savings). - Browser Use / Browser Harness — agent browsing without the C++-level anti-detection focus.
- Commercial stealth-scraping APIs — do the same fingerprint evasion but charge per request.
- Underlying engine: daijro/camoufox — the Firefox fork itself, if you want to build your own wrapper.
⚠️ Note
Anti-detection browsing is dual-use — appropriate for agents accessing sites you’re authorized to use; respect target sites’ terms and rate limits.
