About Postman
Postman grew from a request-testing sidekick into the collaboration hub for API-first teams: collections document endpoints, tests run in CI, mocks unblock frontend work, and workspaces keep everyone honest. Its AI assistant drafts tests and explains responses. Heavy workspaces can lag, and open-source-minded developers eye alternatives, but network effects keep Postman the lingua franca.
