• Genuinely a minute from download to a working mock API.
• Dynamic templating with faker-style helpers produces realistic responses.
• Proxy mode mocks only the routes you need and passes the rest through.

• Schema-driven mocks and assertions stay correct as the API definition changes.
• Meaningfully cheaper than Postman for equivalent team features.
• One tool instead of three for design, mocking and documentation.

• Desktop-first; sharing mocks across a team needs the paid cloud or a committed config file.
• HTTP only.
• Less suited to complex stateful behaviour than WireMock.

• Younger vendor with a smaller community and fewer third-party integrations.
• Data residency and cloud storage need checking for regulated environments.
• Documentation quality is uneven in places.

Front-end developers unblocking themselves while a backend is still being built.
