Two products, Flagsmith and LaunchDarkly, were each named in all six of the six answers we collected, the only two to score a clean sweep. We asked ChatGPT and Gemini six ways a buyer might phrase the same shopping question about feature flag software, ran each question as one live web search, and wrote down every product named and every source link behind the answer. Out of six answers, Flagsmith and LaunchDarkly hit 6 of 6, a 100% appearance rate.
This is one measurement of one category on one day, 2026-08-03, using two assistants: ChatGPT and Gemini. It is not a market-share ranking and not our opinion. It is a record of what these two assistants actually said, with citations, when a buyer asked. Six questions produced six answers and a named list nine products deep.
The two names that never dropped off
Flagsmith and LaunchDarkly each appeared in 6 of 6 answers, the only products to do so. ConfigCat came next at 4 of 6 (67%), then GrowthBook and Unleash tied at 3 of 6 (50%) each. Below them the list thins fast: Flipper Cloud and Kameleoon at 2 of 6 (33%), then Flipt and OpenFeature at 1 of 6 (17%).
The gap between second and third place is the real story. Being named in 6 of 6 answers versus 4 of 6 is the difference between a product a buyer sees every time and one they see two-thirds of the time. Six of the nine named products showed up in half the answers or fewer, which means most of this shortlist is fragile and moves with how the buyer phrases the question.
How the shortlist changed with the question
The bare query "best feature flag software" returned five names: LaunchDarkly, Flagsmith, ConfigCat, Flipper Cloud, and Kameleoon. Not one open-source project made that list. This is where Flipper Cloud and Kameleoon entered, each finishing at 2 of 6 across the whole set, and neither appeared on the "free" or "affordable" questions at all.
Change one word to "best free feature flag software" and the shortlist turns over. That answer named LaunchDarkly, Flagsmith, OpenFeature, Unleash, and GrowthBook. Three names absent from the bare "best" query, the open-source group Unleash, GrowthBook, and OpenFeature, surfaced here. OpenFeature was named in exactly 1 of 6 answers, and this "free" question is the only place it showed up.
"Most affordable feature flag software" produced yet another mix: Flagsmith, ConfigCat, LaunchDarkly, Unleash, and GrowthBook. The free and affordable framings share the open-source pair Unleash and GrowthBook, each named in 3 of 6 answers and only ever on the "what should I use," "free," and "affordable" questions. Neither appeared on the bare "best" query or on "recommendations."
Two products were each named in just one of the six answers. Flipt appeared only on "best feature flag software for small teams," its single mention out of six. OpenFeature appeared only on "best free feature flag software." If you sell either one, you are a single word of phrasing away from being invisible.
The lesson for anyone in this category: there is no one AI answer about your product. "Best," "best free," "most affordable," and "for small teams" are four different shortlists drawn from four different source mixes. Flagsmith and LaunchDarkly cleared all six phrasings; everyone else won some and lost others.
Where the answers came from
Reddit was cited in all 6 answers, the only source of any kind to appear every single time. Quora followed at 5 of 6. Threads where real users argue about tools fed almost every answer we saw, which is worth sitting with before you fund another channel.
Two roundup-style pages carried real weight: octopus.com appeared in 6 of 6 answers and cpoclub.com in 4 of 6. These are the "best feature flag tools" listicles that assistants lean on to build a shortlist, and landing in those two pages did more work here than most vendors would guess.
Here is the key insight. flagsmith.com, a vendor's own domain, was cited in all 6 answers, and Flagsmith the product was named in all 6. A company's own content was not sitting unread; it was a source the assistants pulled from every time, and the product it describes won every question. The pattern repeats: launchdarkly.com fed 4 answers and LaunchDarkly was named in 6 of 6; getunleash.io fed 3 and Unleash was named in 3. When your domain is in the sources, your product tends to be in the answer.
The counter-example matters too. amplitude.com and harness.io were each cited once, yet neither Amplitude nor Harness was named as a feature flag product in any of the six answers. A vendor's domain can feed an answer through a blog post or comparison page without that vendor's own product making the shortlist. Being a source is necessary, not sufficient.
What never appeared: G2 and Capterra. Across six answers and eleven distinct source domains, a classic review directory was cited in 0 of 6 answers. The pages behind these AI answers were community threads, roundup articles, and vendor documentation, not the star-rating aggregators that still absorb most software marketing budgets.
What this means if you sell feature flag software
The source list, not your market share, decides whether an assistant names you. Flagsmith and LaunchDarkly were named in 6 of 6 answers because their own content and the community threads about them sat in the sources every time. There is no separate reputation score the model consults; it names what the pages in front of it name.
That makes the work concrete. Get into the Reddit and Quora threads that fed 6 of 6 and 5 of 6 answers. Get into the octopus.com and cpoclub.com roundups that fed 6 of 6 and 4 of 6. Publish your own comparison and documentation pages, because a vendor domain in the sources, as flagsmith.com showed at 6 of 6, tracks closely with the product getting named.
And notice what is not on that list: a G2 or Capterra placement, which appeared in 0 of 6 answers here. Spending against the directories is spending against pages these two assistants did not cite once for this category.
The full list, counted
| Product | Named in | Share |
|---|---|---|
| Flagsmith | 6 of 6 | 100% |
| LaunchDarkly | 6 of 6 | 100% |
| ConfigCat | 4 of 6 | 67% |
| GrowthBook | 3 of 6 | 50% |
| Unleash | 3 of 6 | 50% |
| Flipper Cloud | 2 of 6 | 33% |
| Kameleoon | 2 of 6 | 33% |
| Flipt | 1 of 6 | 17% |
| OpenFeature | 1 of 6 | 17% |
Share is the percentage of the six answers that named each product. Flipt (1 of 6) and Flipper Cloud (2 of 6) are separate products, the open-source Flipt project and the hosted Flipper service, and are counted separately here rather than merged.
Where Glotier fits
Glotier does not sell feature flag software, so we are correctly absent from all six of these answers, and we would be surprised to see ourselves in them. We have no product in this category for an assistant to name.
This page, though, is the exact thing we run for a category you do sell. We put your buyers' real questions to the AI assistants, record who gets named across the answers, and hand you the source list behind each one, the Reddit threads, the roundups, the domains, so you know where to show up. The same check on your own category is free, needs no account, and takes about a minute.
