Reviewers largely see Postman as a reliable everyday tool for API testing, debugging, and exploratory work, with strong marks for collections, environments, shared workspaces, import/export, and quick regression checks that make team collaboration easier. Several say it helps organize requests, document APIs, and move across dev, QA, and production with less friction. The main complaint is weight: users repeatedly mention high memory use, slow starts, occasional instability, clunky tab management, and some learning curve. Founders of
LayerProof and
Bolna also describe using it across real API build and test cycles.
