Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out.Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required.You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time.With v4, I also added MCP support, so coding agents can create and manage mocks directly, along with an optional built-in AI assistant using your own API k

Mocktail – Free, open-source mock API server with a built-in dashboard is positioned in show hn launch, a segment that rewards a clear, focused offering.

Its current recorded stage is Show HN launch.
