About Browser Harness

Connect an LLM directly to your real browser with a thin, editable CDP harness. For browser tasks where you need complete freedom. One websocket to Chrome, nothing between. The agent writes what's missing during execution. The harness improves itself every run. Try browser-harness in Browser Use Cloud or paste the setup prompt into your coding agent. You will never use the browser again.
