• Fast: no network, no separate server process, no port conflicts in CI.
• Tiny API you can learn in ten minutes.
• Works with whichever runner you already use.

• 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.

• Node.js only, and only for services you host yourself.
• In-process testing skips the real network stack, proxies and load balancer.
• No environment management or collection concept for cross-service flows.

• 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.

Node.js API projects testing their own routes in the unit/integration layer.

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