What the models said for it

Verbatim evidence the judge attached to positive labels.

“FusionAuth is an API-first platform designed for developers that's flexible, affordable, and packed with features.” Claude Haiku 4.5 · CIAM · budget prompt · first choice

“or FusionAuth Community Edition if you want a truly free, self-hosted solution with full control” GLM 4.7 FlashX · CIAM · budget prompt · first choice

“Best free self-hosted option ... For pure cost at any scale, self-host FusionAuth” Grok 4.1 Fast · CIAM · budget prompt · alternative

“Organizations that prefer open‑source, self‑hosted control. | Requires ops expertise” GLM 4.7 FlashX · CIAM · 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.

“Avoid ... open-source like Keycloak/FusionAuth (high ops overhead)” Grok 4.1 Fast · CIAM · direct prompt · hard negative

“caution if your team requires full on-prem control or strict data-residency guarantees” Perplexity Sonar · CIAM · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named FusionAuth. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 42 of the 46 answers that named FusionAuth and are not a share of its labels.

Is this your product?

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 FusionAuth'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 FusionAuth, 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 fusionauth.io 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.
