Active·★ 19·MIT·Updated 2026-10-22

Public Browser lets Claude Code, Cursor and any MCP client drive Chrome by talking to it directly over the Chrome DevTools Protocol. The README reports a blind benchmark against agent-browser and highlights fewer tokens, loud failures and support for nested cross-origin iframes and shadow DOM.
