• 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.

• Nothing to install — genuinely useful for onboarding and for locked-down machines.
• Self-hosting is a single container, so internal deployment is trivial.
• Very light and fast.

• 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.

• Browser CORS restrictions require a proxy or the desktop agent for many real requests.
• Fewer advanced testing and mocking features than Postman.
• Smaller community.

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

Teams that want a self-hosted, no-install internal API client.
