What the models said for it

Verbatim evidence the judge attached to positive labels.

“the best default choice is usually ConfigCat if you want the simplest low-cost managed service” Perplexity Sonar · Feature flags · budget prompt · first choice
“The Best "All-Rounder": ConfigCat ... strikes the best balance between power and simplicity” Qwen 3.7 Flash · Feature flags · direct prompt · first choice
“ConfigCat is probably the best default choice for a mid-market B2B company.” GPT-5.4 mini · Feature flags · direct prompt · first choice
“Offers a "Forever Free" plan, making it the lowest-cost entry point.” Mistral Small · Feature flags · budget prompt · first choice

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.

“Lighterweight option may lack advanced governance, stats, and enterprise features for regulated environments.” GLM 4.7 FlashX · Feature flags · negative prompt · soft negative
“ConfigCat - Operational Limitations - Limited A/B testing capabilities” Kimi K2 · Feature flags · negative prompt · soft negative
“Why to be cautious: Limited Maturity and Experimentation Depth.” Qwen 3.7 Flash · Feature flags · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named ConfigCat. 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 98 of the 113 answers that named ConfigCat 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 ConfigCat'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 ConfigCat, 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 configcat.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.
