jo-inc/camofox-browser

An anti-detection browser server for AI agents that bypasses bot detection through C++ level fingerprint spoofing, exposing accessibility snapshots, stable element refs, and search macros through a REST API.

Project overview

Project type: AI Agent · Infrastructure
Use cases: Automation
Deployment: Refer to project documentation
License: MIT

Best for

Developers and AI engineers building automated agents that require interaction with web pages secured by bot detection systems.
Systems designed to run on shared infrastructure or low-resource devices such as a $5 VPS or Raspberry Pi.

Key capabilities

Wraps the anti-detection engine in a REST API providing accessibility snapshots, stable element refs, and search macros.
Keeps memory at approximately 40MB when idle using lazy browser launch and idle shutdown mechanisms.
Provides isolated user sessions and persists cookies/localStorage to maintain state across browser restarts.

Limitations and risks

The system uses GitHub Issues for anonymized crash and hang telemetry reporting, which may involve external data transmission.

Getting started

Users can initiate the server using the command 'npx @askjo/camofox-browser', which provides clear setup instructions and requires no coding.
