Postman stays widely used because it solves a very common problem well: API work rarely lives in one file or one role. Developers need to test endpoints, product teams want collections that explain behavior, QA needs repeatable requests, and documentation should not drift too far from reality. Postman pulls those layers into one practical workflow, which is why it remains more than just a request sender.
As a platform choice, Postman is strongest when collaboration around APIs matters as much as the requests themselves. If you are searching for the best API testing tool for teams or a practical workspace for API design and debugging, it still deserves a place near the top of the shortlist. The tradeoff is that the platform can feel heavier than minimal tools if all you need is the occasional quick request.
Our recommendation is to use Postman when API workflows need structure: shared collections, environments, testing routines, mocks, onboarding, and team visibility. It is most valuable when the API surface is large enough that ad hoc requests stop being sustainable.
