Why people look for Postman alternatives
Postman is used by development teams to test, mock, document and share APIs, and it is known for shared collections and a broad all-in-one feature set. Its free plan no longer allows team collaboration, so teams now pay per user while a solo plan costs $9 a month, and monitoring calls, Flows credits and AI overages add to the bill.
Developers also dislike the heavy desktop app, the cloud account needed for most features, and collections stored in a proprietary format instead of plain files in the repo. When picking a replacement, decide whether you need a lightweight client, Git-based collaboration, self-hosting or a full design-and-docs platform, and check that it imports Postman collections.
