SuperTest vs Insomnia
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- 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.
Limitations
- 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.
Best for
Node.js API projects testing their own routes in the unit/integration layer.
Developers who mainly want a fast client with excellent GraphQL support.
