The E2E testing landscape settled in 2024-2025. Playwright, backed by Microsoft, has overtaken Cypress as the default recommendation for new projects. The 2025 State of JS survey shows Playwright usage at 54% among E2E test authors, up from 31% in 2023, while Cypress declined from 73% to 58%.
Playwright's core advantages: native multi-browser support (Chromium, Firefox, WebKit in a single test run), true cross-browser parallelism, built-in trace viewer with video, screenshots, and DOM snapshots on failure, and significantly better performance in CI. Playwright runs tests across browsers in parallel by default — a 300-test suite runs in 4 minutes on Playwright where it took 18 minutes on Cypress. The Page Object Model and fixtures system makes test organization clean for large suites.
Cypress strengths: the interactive test runner (with time-travel debugging) is genuinely better than Playwright's UI mode for debugging failing tests in development. Cypress Component Testing (testing React/Vue/Angular components in a real browser without full-page setup) is mature and widely used. For developers who want immediate visual feedback and a gentle learning curve, Cypress remains excellent.
The architectural difference: Cypress runs inside the browser using JavaScript (same origin), which makes some things simple (direct access to the application's JavaScript globals) and some things hard (cross-origin testing, working with multiple tabs, file downloads). Playwright runs outside the browser using the Chrome DevTools Protocol, giving it lower-level access — multiple tabs, cross-origin iframes, network interception, and file system access are all straightforward.
Migration from Cypress to Playwright: Microsoft provides a Cypress-to-Playwright migration tool (npx @playwright/test convert-cypress). It handles ~70% of common patterns automatically. The selectors need updating (Cypress uses .find(), Playwright uses .locator()), and cy.intercept() maps to page.route().
For new projects in 2026: Playwright. For existing Cypress projects: migrate when you feel pain (cross-browser tests, CI performance), not proactively.
