Language and Browser Support

What programming languages and browsers each end-to-end testing tool supports.

Playwright

Offers official bindings for JavaScript/TypeScript, Python, Java, and .NET, with genuine, well-maintained cross-browser support for Chromium, Firefox, and WebKit (Safari’s engine) from a single API.

Cypress

JavaScript/TypeScript only, with browser support historically strongest on Chromium-based browsers and Firefox; WebKit/Safari support has been more limited than Playwright’s.

Selenium

Offers official bindings for Java, Python, C#, JavaScript, Ruby, and more, with broad support across virtually every major browser via each browser’s own WebDriver implementation.

Puppeteer

Primarily JavaScript/TypeScript (with community ports to other languages), and primarily focused on Chromium-based browsers, with experimental Firefox support.

WebdriverIO

JavaScript/TypeScript, with broad cross-browser support inherited from its dual WebDriver/CDP protocol support, plus mobile app automation through Appium integration.

TestCafe

JavaScript/TypeScript, supporting all major browsers since it works through script injection rather than a browser-specific automation protocol.
