• Catches breaking API changes at build time instead of in a shared staging environment.
• The can-i-deploy check is a genuinely good answer to microservice release coordination.
• Broad language support, so polyglot estates can adopt it uniformly.

• 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.

• Requires organisational buy-in from both consumer and provider teams; unilateral adoption achieves little.
• Real conceptual learning curve — most failed adoptions are misunderstandings, not tooling problems.
• Not a substitute for integration testing of behaviour, only of the contract.

• 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.

Microservice organisations where teams deploy independently and integration environments are a bottleneck.

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