Postman

Postman is a collaboration platform for building APIs. Developers use it to handle most stages of an API's life in a single workspace rather than juggling separate tools.

What Postman offers

• API design and mocking — sketch an interface and simulate its responses before the real service exists.
• Testing and debugging — send requests and inspect what comes back.
• Documentation and publishing — produce reference material and make APIs available to others.
• Monitoring — keep watch on how APIs behave over time.
• Extensions — a command-line tool called Newman, the Postman API, an API Network and various integrations.

Key facts

• Platforms: native apps for macOS, Windows and Linux
• Command line: Newman runs collections outside the app
