Browser Harness is the browser-automation layer for AI agents that has quietly taken over from its more-famous parent project. Self-healing in this context means the harness re-plans when a selector breaks or a page state diverges from what the agent expected, rather than failing the run. For agentic browser work (logging in, filling multi-step forms, navigating SPA auth flows, completing checkout), Browser Harness is the library most new projects reach for in 2026. It works with any LLM backend via an OpenAI-compatible adapter. Shipped by the browser-use team, who have been iterating on browser-automation-for-LLMs longer than most of the field.
