Postman

Postman is an API development platform that helps teams design, build, test, document, and monitor APIs throughout the entire lifecycle. It offers tools such as a visual OpenAPI editor, mock servers, automated testing, collection runners, performance monitoring, and SDK generation. Recent features add AI‑driven agents, a CLI with pre‑built skills, and governance capabilities for secure, scalable API management. Postman unifies development, security, and operations so developers can move from code to production faster and with higher quality.
