The problem

Testing against real APIs is slow, flaky, and expensive. WireMock needs a JVM. Mockoon needs Electron. Cloud-hosted mocks add latency and another service dependency. Mirage is a single binary that serves mock HTTP endpoints from SQLite. Define a route, set a response body and status code, and your tests hit a local server that never goes down.

Replaces Mockoon ($9/mo).

Define mock HTTP endpoints with expected responses, test your app against them, simulate error conditions and latency. The local service double every integration test needs. Your data lives in a SQLite file on your disk that you can back up by copying a folder, move to another machine, or query directly with any SQLite tool. The binary keeps running if Stockyard disappears tomorrow, because it is Apache 2.0 and you have a copy.
