Browser Harness
Self-healing harness for LLM-powered browser agents
Visit browser-harness.com ↗What is Browser Harness?
Browser Harness is an open-source framework that connects language models directly to web browsers via Chrome DevTools Protocol. Agents can autonomously complete browser tasks by writing and editing their own helper functions during execution, improving the harness with each task. The system runs on local Chrome instances, stealth browsers, or Browser Use Cloud for scaled parallel execution.
Designed for developers building AI agents, Browser Harness provides a thin abstraction layer that lets agents adapt to new workflows without code changes. It includes an MCP server for integration with Claude Code, Devin, Cursor, and other MCP clients, plus support for features like live previews, proxies, stealth browsing, and CAPTCHA solving when scaled to the cloud platform.
