API design, testing, and documentation in one place.
Postman is an API platform available for Windows, Mac, Linux, and browser, providing a visual interface for designing, testing, and documenting APIs. Collections group related requests together and can be run as automated test suites with pre- and post-request scripts. Environments store variables like API keys and base URLs so collections are reusable across dev, staging, and production. Mock servers simulate endpoints before they are built. Postman's collaboration features allow teams to share collections, sync environments, and review API documentation from a shared workspace. It is the standard tool for API development and testing across small and large engineering teams.
