# Browser Harness

> Open-source browser agent driven via CDP — direct browser control, 79K stars, YC W25. browser-harness gives Claude Code direct, low-level control of a real Chrome browser via the Chrome DevTools Protocol. Coordinate-level clicks pass through iframes, shadow DOM, and cross-origin frames at the compositor level — no selector hunting, no Playwright wrappers. Connects to a long-running Browser Use Cloud or local browser session, so logins persist across runs. Highlights: - Screenshot-first workflo
