VisitMockfly suits frontend, backend, mobile, QA, and testing engineers who need shared mock APIs. It is also useful for teams that want to import API definitions, automate mock management, or serve projects locally offline.
It suits developers who need mock APIs from common specification formats or want to test authentication flows without an external identity provider. The free plan may work for individual projects, while teams can use shared projects and membership controls.
