AI agents cannot browse the web properly. They either have no browser access, or they get a fresh Chrome with no logins, no extensions, and instant bot detection. Playwriter gives them your actual browser session instead. One Chrome extension, full automation API, everything you are already logged into. Includes accessibility snapshots (5-20KB instead of 100KB+ screenshots), a debugger with breakpoints, live code editing, network interception, and video recording. Works with any MCP client: Cursor, Claude, VS Code, and more. Open source, MIT licensed.
