Passmark
AI Playwright regression testing — plain English, Redis caching, auto-healing.
FSL-licensed library from Bug0/Hashnode. Write E2E tests in natural language, cache steps in Redis for native-speed replays, multi-model assertions — runs inside @playwright/test.
Cypress is a widely used JavaScript end-to-end testing framework that's free and open source on its own, with Cypress Cloud (the paid, hosted dashboard for recording runs, parallelization, and analytics) sold separately. Teams looking past Cypress itself are often evaluating newer AI-driven testing approaches — writing tests in plain English and having them auto-heal when the UI changes — rather than maintaining traditional selector-based test scripts.
FAQ
Is there a free, open-source alternative to Cypress?
Passmark is source-available (FSL-1.1-ALv2) and takes a different approach — AI-driven Playwright tests written in plain English with auto-healing, rather than Cypress's traditional scripting model.
What's the best open-source alternative to Cypress?
Passmark is worth a look specifically if you want tests that self-heal when selectors change, which is a different maintenance model than Cypress's explicit test scripts.
