Keploy

Open-source AI API and unit testing generated from real traffic.

About Keploy

Keploy is an open-source testing platform for backend teams. It captures real API traffic and dependency calls with eBPF, then converts them into regression tests, mocks, and sandboxes that replay in CI without code changes. It also generates unit tests with AI. A free hosted Playground tier complements the self-hosted open-source core, while paid plans add collaboration, contract testing, and enterprise controls.
