• 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.

• Noticeably faster and lighter than Postman for everyday request work.
• Best-in-class GraphQL and gRPC ergonomics.
• Design-first OpenAPI workflow with linting built in.

• 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.

• A forced-account change in 2023 damaged trust; check the current model before standardising on it.
• Test scripting is less capable than Postman's.
• Smaller ecosystem of shared collections.

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

Developers who mainly want a fast client with excellent GraphQL support.
