Movement

This is the first edition on this tier, so no move can be computed for Postman yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Postman across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“If your team is very small or just starting, Postman's free tier is often the best entry point.” Mistral Small · API management · budget prompt · first choice
“Postman - if you prioritize developer experience and API design ... It is not a runtime API gateway” Claude Haiku 4.5 · API management · paraphrase prompt · alternative
“Postman is also a solid choice, especially if your team is already familiar with its ecosystem.” Mistral Small · API management · paraphrase prompt · alternative
“Less "heavy gateway" than Kong; great for B2B distribution but pair with a gateway.” Grok 4.1 Fast · API management · paraphrase prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“It is not a production API management platform. The free tier is severely limited for teams” GLM 4.7 FlashX · API management · budget prompt · soft negative
“Free for design/testing, but lighter on full management.” Grok 4.1 Fast · API management · budget prompt · soft negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Postman's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Postman, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at postman.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
