About

GoReplay captures live production HTTP traffic and replays it against staging environments—enabling shadow testing, load testing, and debugging without modifying your application or adding sidecars. This open-source tool sits transparently on your server, intercepting real user requests and sending them to test systems in parallel. Perfect for validating code changes, stress-testing infrastructure, and reproducing production issues in isolated environments. Zero friction integration means you can start testing immediately. Built for developers who need production-grade validation without deployment overhead.
