Cypress

Cypress is an open-source, JavaScript-based end-to-end testing framework favored by developers for its fast in-browser execution and excellent debugging. It offers strong parallelization in CI and a growing AI plugin ecosystem but requires code maintenance. Compared with Rainforest, Cypress gives more technical control and zero licensing cost yet demands engineering time that Rainforest’s no-code AI approach is designed to eliminate for non-technical stakeholders.
