• 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.

• One DSL covers functional API tests, mocks and load tests — rare consolidation.
• Powerful JSON matching that removes most assertion boilerplate.
• Non-Java testers can write meaningful tests.

• 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.

• The custom DSL is another language to learn and cannot be refactored by an IDE.
• Debugging complex scenarios is harder than in plain code.
• The UI automation feature is far behind dedicated browser tools.
