Movement

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

By model

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Keycloak is often the best choice if you have internal IT resources, as it's completely free and feature-rich” Claude Haiku 4.5 · IGA · budget prompt · first choice
“consider open-source platforms like Keycloak or Authentik” DeepSeek V4 Flash · Workforce identity · negative prompt · first choice
“Keycloak: Enterprise-grade (SSO, federation), self-host free. Hidden costs... Great if you have engineers; skip if not.” Grok 4.1 Fast · CIAM · budget prompt · alternative
“a lightweight open-source tool (Keycloak, Authentik, Authelia) ... will keep costs under $50/month” GLM 4.7 FlashX · IGA · budget 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 self-hosting Keycloak unless you have a dedicated, experienced DevOps and Security team” Gemini 3.5 Flash · CIAM · negative prompt · hard negative
“Avoid self-hosted open-source (e.g., Keycloak) unless you have IT resources” Grok 4.1 Fast · Workforce identity · budget prompt · hard negative
“Avoid ... open-source like Keycloak/FusionAuth (high ops overhead)” Grok 4.1 Fast · CIAM · direct prompt · hard negative
“Self-hosted options like Keycloak or FreeRADIUS can be deployed at minimal cost, though they require IT resources for setup and maintenance.” Claude Haiku 4.5 · MFA · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Keycloak. 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 63 answers that named Keycloak and are not a share of its labels.

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 Keycloak'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 Keycloak, 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 keycloak.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.
