• Collections live in Git, so they diff, branch and review like any other code.
• Offline-first with no forced account — a genuine compliance advantage.
• Imports Postman and Insomnia collections, making migration realistic.

• 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.

• No built-in mock servers or monitoring; it is a client and runner, not a platform.
• Younger project with a smaller ecosystem and fewer integrations.
• Team collaboration relies on your Git workflow rather than in-app features.

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

Engineering teams that want API tests versioned alongside the code they test.

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