Postman
API client for building, testing and documenting requests.
DevOpsFreemium4.2 / 5
Postman remains the common language for API work: collections, environments, scripted tests and generated documentation that a whole team can share. For interview prep and backend coursework, being fluent in it is table stakes.
The app has grown heavy and cloud-first; lighter alternatives exist if you only need to fire requests.
What it's genuinely good at
- Collections and environments keep API work organised
- Scripted tests turn requests into a regression suite
- Auto-generated docs from collections
- Universally understood by backend teams
Where it falls apart
- Desktop app is resource-hungry
- Cloud sync is pushed hard over local-only work
- Free team limits are tight

Who should use Postman
- Backend developers testing and documenting APIs
- QA engineers writing request-level tests
- Students learning REST and auth flows
What it costs
Free tier for individuals and small collections; team plans from about $14/user/month.
Frequently asked
Is there a lighter alternative?
Bruno and Hoppscotch are markedly lighter and keep collections in plain files you can commit to git.
Can I use Postman offline?
Largely yes, but several collaboration features assume a signed-in cloud workspace.
