About
Playwriter is a Chrome extension and CLI that lets an agent control your actual Chrome tab instead of spawning a fresh, headless browser. It connects a clicked tab to a local WebSocket relay on localhost and forwards Chrome DevTools Protocol commands, so automation runs inside your existing session with your logins, cookies, and installed extensions. The CLI sends Playwright code through a single execute interface, avoiding large tool schemas while keeping access to the full Playwright API. The product includes accessibility snapshots (text output with locators and diffs) and optional labeled screenshots for spatial context. It supports multiple isolated sessions, real-time collaboration where a user can step in for captchas or consent dialogs, and advanced capabilities like breakpoints, live script/CSS editing, network interception, and MP4 screen recording. Remote access is possible by tunneling the local relay with a token.
