Mock blocked APIs, passthrough ready routes, see live source
Mockphine keeps frontend and QA moving when backends are unstable. It lets teams mock blocked endpoints, pass through ready ones, and prove exactly what served each response; control unmatched routes with strict 404 or fallback passthrough; and inspect served-by source, status, duration, headers, and bodies in Live View. Deterministic matching plus delay/failure simulation helps catch integration bugs before release.
Hey Product Hunt! I'm Cuong, maker of Mockphine.
I built this after too many releases where frontend and QA were blocked by unstable or incomplete backend APIs. Most workflows forced a bad tradeoff: fully mocked (fast but unrealistic) or fully staging (real but flaky).
I started with a tiny local mock server, then evolved it with feedback into:
👉 Route-level modes: Mock / Passthrough / Disabled
👉 Unmatched-route fallback control: strict 404 or passthrough
👉 Live View that shows served-by source + full request/response details
👉 Delay/failure simulation for edge-case testing
🎯 Help small teams ship faster without losing API confidence.
Would love feedback from the community: what's the hardest API integration scenario for your team to test locally today?
