Compare testing tools for web apps, including end-to-end tests, unit tests, integration tests, synthetic monitoring, CI reliability, and browser automation.
A modern web testing stack usually needs more than one tool: fast unit tests, integration tests, browser-level end-to-end coverage, and production checks. Playwright and Cypress compete for E2E testing, Vitest covers fast developer feedback, and Checkly moves browser tests into monitoring.
