Postman

Postman is the world’s most popular API platform, used by millions of developers to design, test, document, and monitor APIs through the entire API lifecycle.

Overview

What began as a simple Chrome extension for sending HTTP requests has become the industry-standard API collaboration platform. Postman lets you craft requests for REST, GraphQL, gRPC, WebSocket, and SOAP APIs, organize them into collections with variables and environments, and automate tests in JavaScript that run locally, in CI, or on schedules as monitors. Teams collaborate in shared workspaces, publish interactive documentation, spin up mock servers before backends exist, and discover APIs through the public Postman API Network. The Postbot AI assistant helps write requests, tests, and documentation from natural language. An ecosystem of integrations with GitHub, CI pipelines, and monitoring tools connects Postman to the rest of the development workflow.
