Playwright

Playwright is the best browser automation tool right now, covering Chrome, Firefox, and Safari/WebKit for testing, scraping, screenshotting, and PDF generation. It gives you a single API to control all three browser engines with auto-waiting, parallel execution, and a built-in test runner.

Apache 2.0, built by Microsoft (the team that originally created Puppeteer at Google). Playwright fixed Puppeteer's biggest limitations: it supports all browsers, has smarter auto-waiting so tests are less flaky, includes codegen (record your clicks and it writes the test), and runs tests in parallel by default.

Everything is free. No paid tier. Microsoft doesn't monetize Playwright directly. It drives adoption of Azure DevOps and GitHub Actions.

The catch: Playwright downloads all three browser engines (~400MB) on install, which can be slow and frustrating in CI. The API surface is huge. It does everything, which means more docs to read. And while the test runner is excellent, migrating an existing Cypress or Selenium test suite takes real effort. If your tests are already working in Cypress and you're happy, switching has a cost.
