When teams evaluate modern end-to-end testing frameworks, one of the most common comparisons is Playwright vs Cypress. Both tools are widely used for testing modern web applications, but they differ in architecture, browser support, performance, and testing capabilities. Playwright, developed by Microsoft, focuses on cross-browser automation and modern testing workflows, while Cypress emphasizes developer experience and fast in-browser testing. In this guide, we’ll break down the key differences between Playwright and Cypress, including performance, parallel execution, language support, and when each framework makes the most sense.
