Free alternatives to Postman
2 free programs that can replace Postman, each pairing checked by Radar's AI reviewer or by Radar.
Postman is a platform for working with APIs: developers and testers use it to send requests, organize them into collections, write tests, document APIs and share all of that with their team. Many of its team features depend on an account and paid plans.
Before moving to Bruno or Insomnia, check:
- Collections: import a real collection with its environments, then run your most important requests to see what broke.
- Scripts: pre-request scripts and automated tests may use features that do not exist in the new tool.
- Sharing: if the team works in shared workspaces, decide how collections will be shared afterwards, for example in a code repository.
- Extras: mock servers, monitors and published documentation may need other tools.
- Automation: check how your tests run in your build pipeline.
