Playwright

Supports Chromium, Firefox, and WebKit browsers on Linux, macOS, and Windows for comprehensive cross-browser coverage.

Automatically waits for elements to be actionable and retries assertions until conditions are met to reduce flaky tests.

Each test runs in a fresh browser context, providing full isolation with minimal overhead and enabling reuse of authentication states.

Runs tests in parallel across all configured browsers and supports sharding across multiple machines for faster continuous integration.

Finds elements using user-centric selectors like roles, labels, placeholders, and test IDs instead of brittle CSS paths.

Provides a detailed timeline of test execution with DOM snapshots, network requests, console logs, and screenshots to aid debugging.

Records user actions in the browser and generates test code with assertions and locators from the recording toolbar.

Includes Model Context Protocol server and CLI for AI agents to control browsers through structured accessibility snapshots and commands.
