Verdict at a glance
Both are excellent. Cypress wins on first-day developer experience. Playwright wins on second-year production needs — multi-domain auth, multi-tab flows, and real Safari/WebKit coverage without a third-party grid.
Architecture & model
Cypress runs your test code inside the browser, in the same event loop as the app. That’s why the runner feels so magical — time-travel, automatic re-execution on save, no IPC layer between your assertions and the page.
Playwright runs out-of-process and drives the browser via CDP (or WebKit’s remote protocol). That’s why it can do things Cypress structurally can’t: open a fresh browser context for every test, manage multiple origins, drive mobile emulation, and parallelize across cores trivially.
Cross-browser story
Playwright is built around a unified API that drives Chromium, Firefox, and WebKit. Cypress added Firefox and WebKit support over time, but WebKit in particular remains experimental as of writing.
Debugging
Cypress’s interactive runner is the gold standard for “watch a test run and poke at it.” Playwright’s trace viewer is the gold standard for “a test failed at 3 AM in CI and I need to know why.”
Cost considerations
Cypress Cloud (formerly Dashboard) is excellent but priced per recorded test result. Teams hit the free-tier ceiling quickly and then face a real budget conversation. Playwright’s HTML report is free, self-hosted, and sufficient for most teams.
Final recommendation
If your product is a single web app and your top priority is “make every engineer comfortable writing tests on day one” — choose Cypress. If you need cross-browser, multi-context, or you’re cost-sensitive about a SaaS dashboard, choose Playwright.
