Playwright

Playwright is an open-source framework for web automation, testing, and AI agent control. It supports Chromium, Firefox, and WebKit, providing a single API for driving these browsers across various programming languages including TypeScript, Python, .NET, and Java. The framework offers features like auto-waiting and web-first assertions for end-to-end testing. For AI agents, Playwright includes a Model Context Protocol (MCP) server, which provides structured accessibility snapshots for deterministic browser interaction and full browser control.
