Automation & Integration

Best API Testing and Management Tools

For API testing, pick Postman if your team collaborates heavily and wants monitoring built in, or Bruno if collections should live in Git. Add Stoplight for design-first API programs and Kong only when you need a production gateway.

Postman alternatives

If you only use Postman to send requests and run tests, switch to Bruno for a free, Git-first setup, or Insomnia for the closest like-for-like tool. Stay on Postman if you rely on its monitors, governance or API catalog.
