Playwright

Playwright is Microsoft's open-source framework for web automation, driving Chromium, Firefox and WebKit through one API in TypeScript, Python, .NET and Java. Its test runner auto-waits for elements, retries assertions and isolates each test in a fresh browser context, with role-based locators, tracing, parallel runs and a test generator that records your clicks. Start with Playwright MCP or the token-efficient CLI, which give coding agents like Claude Code browser control through accessibility snapshots.
