# CI/CD platforms: what fourteen AI models recommend, and why, November 2026

Gane Index, November 2026 Edition. Page: https://www.gane.ai/index/it/developer/ci-cd-platforms/guide

Fourteen AI models were asked for CI/CD platform six ways each, on behalf of a small, a mid-market and an enterprise B2B company: 252 answers, in which a judge labeled 50 products. Two of them carry at least 10 labels and a first choice, and are ranked. This guide walks the top two in the order the mid-market standing puts them, with what the models said for and against each, in their words. GitHub Actions leads at 70% of first choices, a clear leader.

## At a glance

| # | Product | Share | Negative rate | Labels |
|---|---|---|---|---|
| 1 | GitHub Actions | 70% | 8% | 75 |
| 2 | GitLab CI/CD | 30% | 10% | 79 |

## 1. GitHub Actions

GitHub Actions is #1 of 2 at 70% of first choices, 75 labels, negative rate 8%. By buyer: small business #1 of 3 at 88%; mid-market #1 of 2 at 70%; enterprise #2 of 9 at 18%.

- For: "the safer default is the CI/CD system integrated with the existing source-control platform—such as GitHub Actions, GitLab CI/CD, or Bitbucket Pipelines" (Perplexity Sonar, negative prompt)
- For: "For 80% of mid-market B2B software companies, GitHub Actions (if on GitHub) or GitLab CI/CD (if on GitLab) provides the best balance" (Gemini 3.5 Flash, direct prompt)
- Against: "GitHub Actions as your only delivery path, if outages would stop critical releases... That doesn't make Actions a bad choice" (GPT-6 Luna, negative prompt)
- Against: "GitHub Actions — supply-chain caution ... treat workflow logs, secrets handling and third-party actions as high-risk." (Muse Glimmer 30B, negative prompt)

## 2. GitLab CI/CD

GitLab CI/CD is #2 of 2 at 30% of first choices, 79 labels, negative rate 10%. By buyer: small business #2 of 3 at 8%; mid-market #2 of 2 at 30%; enterprise #1 of 9 at 54%.

- For: "GitHub Actions (if on GitHub) or GitLab CI/CD (if on GitLab) provides the best balance of speed, security, and developer experience" (Gemini 3.5 Flash, direct prompt)
- For: "The Top Contender: GitLab CI/CD ... or GitLab CI if you need a broader toolset or prefer a unified dashboard" (Qwen 3.7 Flash, paraphrase prompt)
- Against: "Self-hosted installations of any platform without a security owner: Jenkins, GitLab, TeamCity, and similar systems can be risky" (Perplexity Sonar, negative prompt)
- Against: "GitLab has been flagged for: An accelerating frequency of service disruptions (76 incidents in 2023 → 97 in 2024)" (MiniMax M2.5, negative prompt)

## Questions the record answers

**Which CI/CD platform do AI models name first most often?** GitHub Actions, in 70% of first choices for a mid-market B2B company in the November 2026 Edition, from 75 labels. The index calls that a clear leader.

**Does the answer change with the size of the company?** Small business: GitHub Actions at 88%. Mid-market: GitHub Actions at 70%. Enterprise: GitLab CI/CD at 54%. Each standing is computed within its segment and never pooled.

**Which framing changes the answer?** The direct, paraphrase, budget and scale framings count toward share. The leader is the same on all six. The table above has the counts.

**How stable is one answer?** The repeat measurement is published with the next edition.

**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 65 answers here cite 653 pages; the sites cited most are northflank.com, blog.jetbrains.com, github.com. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
