• 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.

• 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.

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

• 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.

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

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