What Postman AI is

Postman is an API development platform. It started as a client for sending HTTP requests and now covers the whole lifecycle: designing and mocking APIs, writing and running collections of requests, automated tests, documentation and monitoring. Teams keep collections in shared workspaces, so a change to an endpoint is visible to everyone who depends on it. The AI features generate request bodies and tests from a description, explain responses and help debug failures. It supports REST, GraphQL, gRPC and WebSocket, and collections can run in CI through the CLI. The limits are that the desktop client is heavy, free-tier collaboration is capped, and API governance features sit on higher plans. Environment variables and saved authorisation settings mean a request can move from a local machine to staging without editing it. Mock servers let a front-end team work before the real API exists, and generated documentation stays in sync with the collection.

Best for

Exploring and debugging an API by hand
Sharing a collection of requests across a team
Running contract tests in CI from the same collection

Not ideal for

Very light scripting where curl is enough
Teams that need API gateway and governance features

Pros

Requests, tests, docs and mocks in one workspace
Collections run in CI without rewriting them
Supports REST, GraphQL, gRPC and WebSocket

Cons

Desktop client is resource-heavy
Free tier caps shared runs and collaborators
Governance and security features need higher plans

Pricing in detail

The free plan covers a limited number of collection runs per month and a small team. Paid plans are billed per user per month and raise run limits, add shared workspaces, roles, API governance and private documentation; enterprise terms are quoted. Because the metered item is collection runs rather than requests, CI-heavy teams hit the limit before individual developers do.
