What the models said for it

Verbatim evidence the judge attached to positive labels.

“For a typical mid-market B2B team, GrowthBook offers the best balance of capability, affordability, and flexibility” DeepSeek V4 Flash · Feature flags · direct prompt · first choice
“Always prioritize platforms (like DevCycle, GrowthBook, and others) that support the OpenFeature standard.” Gemini 3.5 Flash · Feature flags · negative prompt · first choice
“The best feature flag platform for a company with a limited budget is Statsig, Flagsmith, or GrowthBook.” Llama 4 Maverick · Feature flags · budget prompt · first choice
“Best overall for a tight budget: GrowthBook” DeepSeek V4 Flash · 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.

“Advanced governance and stats features vary by plan; may need upgrades for stricter requirements.” GLM 4.7 FlashX · Feature flags · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named GrowthBook. 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 85 of the 98 answers that named GrowthBook 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 GrowthBook'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 GrowthBook, 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 growthbook.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.
