Postman: vendor profile

In short

Postman publishes docs straight from a collection, and each published page holds only the collection title and meta description in its HTML. Request details appear after JavaScript runs. Postman's own comparison puts llms.txt on the Fern side only. Solo costs $9 a month billed annually.

Postman Docs platform

Postman is an API platform that publishes reference docs straight from a collection to documenter.getpostman.com or a custom subdomain, renders those pages in the browser, and gets llms.txt and AI search only through the Fern documentation option it added after buying Fern.

What it does not do

Postman's classic published documentation puts only the collection title and meta description in its initial HTML; request details appear after JavaScript runs.
Postman's publish flow only accepts collections of HTTP requests, so a GraphQL, gRPC or WebSocket collection gets no published docs page.
