-Keploy is an AI-powered testing agent and sandboxing platform that automatically generates test cases, dependency mocks, and production-like sandboxes from real user traffic. It records live API calls at the socket level — with eBPF in the kernel on Linux, and in user space on macOS and Windows — and replays them as deterministic tests, requiring zero code changes and scaling test coverage with AI-driven code velocity. On Linux, and with Docker, it works with any programming language or framework; natively on macOS and Windows it covers Go, Node.js, Python and Java apps — see [Installing Keploy](/docs/server/installation/) for what each platform supports. Keploy enables production behavior replay, dependency virtualization for databases and external APIs, legacy application testing without code changes, and migration regression testing against production baselines.

 Keploy creates backend **API tests with built-in-mocks** or stubs **by recording your application network calls** making
 your testing process not only faster than unit tests but also incredibly efficient.
