About Postman

Postman is a widely used API platform that started as a simple request client and grew into a suite for designing, testing, documenting and monitoring APIs. Collections group requests with variables, scripts and tests, workspaces let teams share them, and mock servers and monitors support the API lifecycle. It supports REST, GraphQL, gRPC and WebSockets. Over time Postman moved toward cloud accounts and team workspaces, which pushed some developers who prefer offline, file-based collections toward alternatives. A free plan is available, with paid plans for larger teams.

Best for: Teams that want a full API lifecycle platform.
