• Fast: no network, no separate server process, no port conflicts in CI.
• Tiny API you can learn in ten minutes.
• Works with whichever runner you already use.

• 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.

• Node.js only, and only for services you host yourself.
• In-process testing skips the real network stack, proxies and load balancer.
• No environment management or collection concept for cross-service flows.

• 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.

Node.js API projects testing their own routes in the unit/integration layer.

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