Postman

About

Postman is the API workbench most teams already share: build a request, inspect the response, save it into a collection, and keep the environment variables that make it portable between local, staging and production. Collections carry tests, and the Collection Runner replays them with a pass or fail report, while mock servers, monitors and Flows cover the rest of the API lifecycle without leaving the app. A spec written in OpenAPI or GraphQL can be generated, linted and published as branded documentation, workspaces sync across machines and teammates, and Git integration keeps the definitions in your own repository. It is free for individuals, with AI credits and team governance in the paid tiers.
