What is Mockphine?

Mockphine is a local mock API server that helps developers and QA teams ship faster by providing deterministic API control with explicit passthrough rules and real-time visibility. It eliminates API uncertainty by letting teams route each endpoint with mock, passthrough, or disabled modes while inspecting served-by and payload details instantly. Built for frontend teams, QA managers, and full-stack engineers who need reliable local API behavior without backend delays.
