Keploy

Keploy is an open-source platform that automates API testing by recording real API traffic in production and replaying it as regression and integration tests in isolated sandboxes. It provides instant test coverage, auto-mocking of dependencies, and detailed coverage reporting, enabling teams to catch regressions and performance issues quickly. Ideal for engineering teams looking to keep up with fast-paced, AI-driven code delivery, Keploy minimizes test-writing overhead and infrastructure costs.
