Mockzilla may suit developers creating mock APIs for frontend work, tests or demos. The listed plans also address side projects, solo developers, small teams and teams with CI pipelines.
WireMock is aimed at developers, testers, and AI coding agents building or validating software against simulated APIs. The free plan suits limited use, while Enterprise adds governance and stateful simulation features.
