Playwriter

Playwriter is a Chrome extension and CLI that lets agents control a real browser with logins, extensions, and cookies already there. It does not launch a headless Chrome and emphasizes staying in the user’s existing session. It aims to avoid bot detection and extra memory usage while exposing Playwright API access through a single tool.

The tool connects your agent to your actual browser, using the extension to forward CDP commands to Chrome and returning responses. It supports multiple sessions and lets agents operate with the real browser state, including cookies and extensions.

There are built-in workflows for recording and replaying browser actions, and it supports debugging, network inspection, and live edits via Playwright-compatible APIs. It can work with local and remote setups, including remote access scenarios via tunnels.

Security and remote access are addressed through local relays and optional tunnels, with token-based authentication and restrictions on extension endpoints. Users can revoke remote access by terminating the connection, and the system emphasizes access control and visibility into browser actions.

Use cases

• QA testing against a real browser with login state
• API reverse engineering and SDK generation
