E2E test framework that runs inside the browser — time-travel between steps, hot reload, beautiful UI.
Revolutionised frontend testing in 2017 with its interactive test runner. Limitation: historically Chromium-only (Firefox came late, no WebKit). Cross-domain testing is hacky. Has lost momentum to Playwright since 2022 on large projects; retains a strong React-world following. Cypress Cloud (paid) provides parallelised test orchestration.
