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.

“Best for Tool Consolidation & Generous Free Tier: PostHog... incredibly generous free tier of 1 million feature flag requests per month” Gemini 3.5 Flash · Feature flags · budget prompt · first choice
“Start with PostHog if you want to track data alongside your flags.” GLM 4.7 FlashX · Feature flags · budget prompt · first choice
“Best default for a budget-conscious company: PostHog.” GPT-6 Luna · Feature flags · budget prompt · first choice
“self-hostable open-source options such as Flagsmith, Unleash, PostHog, Flipt and GrowthBook for full control and zero vendor lock-in” Muse Glimmer 30B · Feature flags · negative 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.

“PostHog experienced four separate incidents in 10 days (Oct 2025), totaling 14+ hours of cumulative impact on flag evaluations” Kimi K2 · Feature flags · negative prompt · soft negative
“the feature flagging capabilities in these platforms are often "second-class citizens" compared to dedicated tools” Gemini 3.5 Flash · Feature flags · negative prompt · soft negative

As the event pages on posthog.com state them, read September 28, 2026.

How it is countedHide how it is counted

Every page posthog.com 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. Read September 29, 2026.

What a new claim receivesHide what a new claim receives

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

  • where PostHog Feature Flags 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 PostHog Feature Flags, 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.
