Postman started as a Chrome extension for testing REST APIs and evolved into the most widely used API development platform. It lets you build and send HTTP requests, organize them into collections, write test scripts, and share them with your team. Postman's mock servers let you prototype APIs before building them, and its documentation generator creates interactive API docs from your collections. The platform supports REST, GraphQL, WebSocket, and gRPC protocols. For teams, Postman provides workspaces for collaboration and monitors that run collections on a schedule to verify API health.
