Keploy Review 2026

Open-source, AI-powered testing agent that automatically generates test cases, dependency mocks, and production-like sandboxes from real user traffic using eBPF. Helps developers achieve 90% test coverage in minutes with zero code changes.

Keploy is an open-source AI-powered API testing agent that automatically generates test cases and dependency mocks from real user traffic using eBPF, achieving up to 90% test coverage in minutes with zero code changes — and it's completely free for the open-source version. It's built for backend developers, QA engineers, and DevOps teams who want to eliminate the manual toil of writing unit and integration tests while ensuring production-like reliability in CI pipelines.

Based on our analysis of 870+ AI tools in the directory, Keploy stands out in the developer testing category by using record-and-replay methodology powered by eBPF kernel-level instrumentation. Instead of writing tests by hand, developers simply run their application through Keploy, which captures real API calls along with their database queries, Redis calls, and third-party service interactions. These captured traffic samples are then converted into deterministic test cases with auto-generated mocks, creating an isolated sandbox environment that can be replayed in CI for regression testing. The project has earned 15,600+ GitHub stars, surpassed 1.2M+ downloads, and generated over 200M+ mocks across its user base — a strong indicator of real-world adoption.
