Playwright
Playwright enables reliable end-to-end testing for modern web apps.
About Playwright
Playwright is a browser automation library for end-to-end testing of web applications, providing a single API to drive Chromium, Firefox, and WebKit browsers. It is available for TypeScript, Python, .NET, and Java, and includes a full-featured test runner with auto-waiting, web-first assertions that automatically retry, test isolation through fresh browser contexts, and resilient locators such as getByRole, getByLabel, getByPlaceholder, and getByTestId. It supports parallel test execution and sharding across machines, and runs on Linux, macOS, and Windows in headless or headed mode.
Beyond testing, Playwright provides tooling for browser scripting and AI agent workflows. This includes a Playwright CLI for coding agents like Claude Code and GitHub Copilot, offering token-efficient, skill-based browser automation, and a Playwright MCP server that gives AI agents structured browser control through accessibility snapshots rather than screenshots, compatible with clients such as VS Code, Cursor, Claude Desktop, and Windsurf.
Additional tooling includes a test generator that records browser actions and produces test code, a Trace Viewer for reviewing full execution timelines with DOM snapshots, network requests, console logs, and screenshots, a VS Code extension for running, debugging, and generating tests in the editor, and a session monitoring dashboard with live screencast previews of running browser sessions. The product is aimed at developers writing automated tests and at coding agents performing browser automation tasks.
