Why Playwright?

Playwright enables fast, reliable and capable testing and automation across all modern browsers. This guide covers those key differentiators to help you decide on the right tool for your automated tests.

Support for all browsers#

  • Test on Chromium, Firefox and WebKit. Playwright has full API coverage for all modern browsers, including Google Chrome and Microsoft Edge (with Chromium), Apple Safari (with WebKit) and Mozilla Firefox.
  • Cross-platform WebKit testing. With Playwright, test how your app behaves in Apple Safari with WebKit builds for Windows, Linux and macOS. Test locally and on CI.
  • Test for mobile. Use device emulation to test your responsive web apps in mobile web browsers.
  • Headless and headed. Playwright supports headless (without browser UI) and headed (with browser UI) modes for all browsers and all platforms. Headed is great for debugging, and headless is faster and suited for CI/cloud executions.

Fast and reliable execution#

  • Auto-wait APIs. Playwright interactions auto-wait for elements to be ready. This improves reliability and simplifies test authoring.
  • Timeout-free automation. Playwright receives browser signals, like network requests, page navigations and page load events to eliminate the need for sleep timeouts that cause flakiness.
  • Fast isolation with browser contexts. Reuse a single browser instance for multiple isolated execution environments with browser contexts.
  • Resilient element selectors. Playwright can rely on user-facing strings, like text content and accessibility labels to select elements. These strings are more resilient than selectors tightly-coupled to the DOM structure.
