Playwright

Playwright is a framework for end-to-end testing and browser automation. It drives Chromium, Firefox, and WebKit through a single API, so one test suite covers the engines behind Chrome, Edge, Safari, and Firefox.

Tests run headless or headed across Windows, macOS, and Linux, with auto-waiting that removes flaky timing code, network interception, isolated browser contexts, and a trace viewer that records each step for debugging. Bindings cover JavaScript, TypeScript, Python, Java, and .NET, and a code generator turns recorded actions into runnable scripts.

Maintained by Microsoft under the Apache 2.0 license, it downloads browsers on demand and runs entirely on your own machines or CI, with no account or hosted service required.
