Movement

This is the first edition on this tier, so no move can be computed for CircleCI yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated CircleCI across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“GitLab CI/CD or CircleCI are excellent choices due to their balance of features, ease of use, and scalability” Mistral Small · CI/CD · paraphrase prompt · first choice
“I'd recommend considering GitLab or CircleCI as top choices” MiniMax M2.5 · CI/CD · direct prompt · first choice
“worth considering if you need stronger performance or parallelism, but budget-conscious guides still tend to put GitHub Actions ahead” Perplexity Sonar · CI/CD · budget prompt · alternative
“Best if you want a dedicated CI/CD product with stronger pipeline orchestration and enterprise features: CircleCI” GPT-5.4 mini · CI/CD · direct 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.

“Avoid CircleCI initially: While powerful, its pricing model can spiral quickly” Qwen 3.7 Flash · CI/CD · budget prompt · hard negative
“In January 2023, CircleCI suffered a severe breach... you are trusting a third party that has proven it can be breached” DeepSeek V4 Flash · CI/CD · negative prompt · soft negative
“Major 2023 breach—malware on an engineer's laptop stole session tokens, exposing customer encryption keys” Grok 4.1 Fast · CI/CD · negative prompt · soft negative
“CircleCI (with caveats)... there have been concerns about its long-term viability and security posture.” Mistral Small · CI/CD · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named CircleCI. 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 127 of the 161 answers that named CircleCI 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 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.

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 circleci.com 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.
