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.

Verbatim evidence the judge attached to positive labels.
“GitHub Actions or CircleCI are the best starting points due to their generous free tiers and ease of use” Mistral Small · CI/CD · budget prompt · first choice
“CircleCI or GitLab CI are the best CI/CD platforms due to their balance of features, scalability, and cost” Mistral Small · CI/CD · direct prompt · first choice
“CircleCI if its execution environments, concurrency, or existing workflows are a particularly good match.” GPT-6 Luna · CI/CD · direct prompt · alternative
“CircleCI | Best-of-breed standalone CI/CD | Performance, reliability, strong enterprise support” Kimi K2 · CI/CD · scale prompt · alternative
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.
“most companies have migrated to GitHub Actions to avoid paying for two separate platform subscriptions” Gemini 3.5 Flash · CI/CD · direct prompt · soft negative
“solid standalone CI tool, but it's CI-focused (not full CD) and has faced pricing pressure” DeepSeek V4 Flash · CI/CD · paraphrase prompt · soft negative
“Best for: Speed-critical builds, though free tier is more limited than competitors” Kimi K2 · CI/CD · budget prompt · soft negative
“evaluate CircleCI, but expect higher cost and migration effort vs staying native” Muse Glimmer 30B · CI/CD · direct prompt · soft negative
Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 151 of the 177 answers that named CircleCI and are not a share of its labels.
416 of the 461 domain citations in answers naming CircleCI came from somebody else's page.
Pages are listed as the models cited them.
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.

Every page circleci.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.

An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

What CircleCI's own pages state, read September 28, 2026: circleci.com, circleci.com/pricing, trust.circleci.com, circleci.com/product, circleci.com/customers. A claimed page can correct any of them.
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 CircleCI'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 CircleCI, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
A new claim receives the current edition's vendor brief for CircleCI by email, built from the raw record of the edition. It shows:
CircleCI is among the products AI models recommend first in CI/CD platforms this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
Badges read on light and dark pages. Alt text carries the claim, the category, the edition and the index, so it stays a citation where the image does not load.
