REST Assured vs Apidog
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- 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.
Limitations
- 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.
Best for
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.
