| 2 | MO Mockphine Mockphine keeps frontend and QA moving when backends are unstable.

Deterministic matching plus delay/failure simulation helps catch integration bugs before release. | |

API mocking tools let you stand up pretend endpoints that behave like a real service. You describe routes, methods, headers, and sample payloads. The tool hosts these routes and returns the responses you define, so apps can call them as if they were live.
