Postman is where most people who work with APIs already work. The client sends requests, Collection Runner automates workflows, Spec Hub manages specifications, mock servers stand in for services that do not exist yet, monitors watch performance, and Flows builds visual workflows without code.
The AI layer is what earns it a place in a directory like this one. AI Engineer builds, tests and maintains APIs rather than answering questions about them, Agent Mode automates workflows natively, and the Postman MCP Server hands API context to external agents, which is the piece that matters as more code is written by something that needs to know what an endpoint expects.
Free covers individuals, then $9, $19 and $49 per user a month billed annually. The platform has grown broad enough that new users meet a lot of surface before they find what they came for, the free tier’s limits arrive quickly once a team shares collections, and per-user pricing scales with headcount rather than usage.
