What is Postman?
Postman is an API development platform that lets you build, test, and document APIs. At its core, it's a powerful HTTP client with collections, environments, automated testing, and team collaboration — all in one place.
Its greatest value is making API work collaborative. Instead of sharing curl commands in chat, teams share collections with pre-built requests, tests, and documentation that everyone can run.
How We Tested
- Built and tested 3 real APIs — REST and GraphQL

- Tested team collaboration and the CLI
What We Loved

Cons
- Can feel heavy for quick requests

Pricing
- Free: Unlimited requests, 3 collaborators — genuinely capable
- Pro ($12/month): Unlimited collections, advanced testing
- Team ($18/month): Unlimited collaborators, SSO, governance

Who Should Use It
Perfect for: backend developers, frontend developers consuming APIs, QA teams, and anyone who works with APIs regularly.
Not ideal for: developers who only occasionally hit an endpoint (a simple tool like Insomnia or a browser console suffices), or teams needing deeply specialized testing frameworks.
