• API tests live in the codebase, versioned and reviewed with the service.
• Readable given/when/then chains that map directly onto HTTP semantics.
• Full access to Java for setup, data and assertions.

• 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.

• Java only, and requires developers rather than manual testers.
• No GUI, so exploratory request work needs a separate client.
• Verbose for very large payload assertions.

• 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.

JVM teams that want API tests in the same repository as the service.

Teams doing design-first API development who want mocks and docs generated from the spec.
