What is Postman?
Postman is an API development platform used by over 30 million developers and 500,000 organizations worldwide. It provides a unified workspace for designing, testing, documenting, and monitoring APIs across HTTP, GraphQL, gRPC, WebSocket, and MQTT protocols. Teams can collaborate through shared workspaces, collections, and mock servers while maintaining version control via native Git integration. The platform includes an AI-powered agent mode for automating repetitive API tasks, an API catalog for internal service discovery, and a CLI for CI/CD pipeline integration. Postman supports the full API lifecycle from spec design through production monitoring, making it the industry standard for API-first development workflows.
