Playwriter

Playwriter is a tool designed to allow agents to control a real Chrome browser, leveraging the full Playwright API. It addresses the challenge of browser automation and interaction by enabling agents to work directly within a user's existing browser environment, preserving logins, extensions, and cookies, and thus avoiding issues such as bot detection and the overhead of spawning new browser instances. The platform supports both a Chrome extension and a command-line interface (CLI), offering flexibility in how agents and developers interact with browsers.

The tool provides a range of features including session management, network interception, screen and video recording, snapshots, visual labels, and a live code editor. It supports direct connections to Chrome DevTools Protocol (CDP), headless mode, and can be used for remote browser control across machines, including setups involving Docker, virtual machines, and SSH. Playwriter also offers debugging tools such as JavaScript and CSS inspection, breakpoint setting, and React component inspection. Its architecture emphasizes security, with sandboxed filesystems and cookie safety measures.

Playwriter is suitable for use cases such as web development, quality assurance testing, task automation, API reverse engineering, remote support, and troubleshooting. The tool is intended for agents and developers who require advanced browser automation and diagnostic capabilities without the limitations of traditional browser automation tools that start fresh browser instances or restrict available features.

Delivery is through both a Chrome browser extension and a CLI, with additional support for remote access and integration into cloud or headless environments.
