Postman

Overview

A workbench for testing APIs, which are the connections that let software systems talk to each other. You send requests and see what comes back.

General use

Developers use it to check that an API works, document how it behaves, and share ready made request collections with teammates.

Insight

Fine for poking at an API by hand and sharing a set of sample requests with the team. Over the years it has piled on accounts, logins, and cloud sync that many people did not ask for, and it now pushes you to sign in and store your work online. For simple checks, lighter tools do the job with less friction. Best when a team genuinely needs shared, documented request collections in one place.
