Playwright

Modern browser automation from Microsoft. Auto-wait, role-based selectors, cross-browser, fast in CI.

Save

Playwright is the browser automation library that replaced Cypress as the default choice for new projects in 2026. Microsoft ships it with first-class support for Chromium, Firefox, and WebKit; auto-waiting that eliminates most of the flake that made Selenium and Cypress painful; role-based selectors that survive refactors and document accessibility; and a TypeScript API that is actually pleasant to use. The test runner is faster than Cypress in CI by a meaningful margin. For any new project that needs end-to-end browser tests, visual QA, or reproducible user-flow checks, this is the pick.

Pricing: Playwright - free and open source under Apache-2.0
Install: npm init playwright@latest
npm install -D @playwright/test@latest

Models: Not an AI tool itself: one API drives Chromium, Firefox, and WebKit (1.64 ships Chromium 156, Firefox 157, WebKit 27.2), with mobile emulation for Chrome on Android and Mobile Safari. For agents, Playwright MCP and playwright-cli expose the same browser control and video options.
Recent changes: Oct 14v1.64.1 fixes a lost first window in packaged apps and a preflighted cross-origin redirect regression.
Oct 7v1.64.0 adds page.webmcp for testing tools a page registers through WebMCP (also on by default in Playwright MCP), custom-fps VP9 video recording, locator.within(), a --shuffle flag, and a testProject.default option.
Sep 4v1.63.0 adds named test locks, frame-agnostic frameLocator(), locator.visible(), and aria and screen snapshots in traces; drops Ubuntu 20.04 and freezes the experimental component-testing packages.
