• 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.

• Nothing to install — genuinely useful for onboarding and for locked-down machines.
• Self-hosting is a single container, so internal deployment is trivial.
• Very light and fast.

• 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.

• Browser CORS restrictions require a proxy or the desktop agent for many real requests.
• Fewer advanced testing and mocking features than Postman.
• Smaller community.

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