• 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.

• YAML workflows are easy to review in a pull request and need no runtime knowledge.
• Generates a starting suite from an OpenAPI spec.
• Includes basic load-testing capability in the same file format.

• 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.

• YAML hits a ceiling on complex conditional logic.
• Small project with limited community support.
• Ecosystem and reporting are thin compared to established tools.

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

Small teams wanting declarative, repo-versioned API checks in CI.
