Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“GrowthBook and PostHog are free to start, and both are open-source so that you can self-host them, making them excellent choices if you want zero upfront costs.” Claude Haiku 4.5 · Experimentation · budget prompt · first choice
“The Alternative: If your program is engineering-led, opt for server-side testing or warehouse-native platforms (such as GrowthBook, Eppo, or PostHog)” Gemini 3.5 Flash · Experimentation · negative prompt · first choice
“GrowthBook is open-source A/B testing and feature-flagging platform, and it is the pick when budget is your tightest constraint.” Muse Glimmer 30B · Experimentation · budget prompt · first choice
“GrowthBook stands out as the best website experimentation and personalization platform for companies with a limited budget.” Grok 4.20 · Experimentation · 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.

“requiring less technical overhead than developer-heavy solutions like GrowthBook” Qwen 3.7 Flash · Experimentation · paraphrase prompt · soft negative
“Open-source, requires more technical setup” Kimi K2 · Experimentation · scale 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, five of the fourteen in this edition, so these counts come from 71 of the 72 answers that named GrowthBook and are not a share of its labels.

Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Events in person

Last twelve months

As the event pages on growthbook.io state them, read September 28, 2026.

How it is countedHide how it is counted

Every page growthbook.io exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person.

What GrowthBook's own pages state, read September 28, 2026: growthbook.io, growthbook.io/pricing, trust.growthbook.io, growthbook.io/platform/security, growthbook.io/customers. A claimed page can correct any of them.

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 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.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for GrowthBook by email, built from the raw record of the edition. It shows:

  • where GrowthBook is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name GrowthBook, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at growthbook.io is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
