At a glance
What we observed in this category
Docker Hub leads the container registry category with a composite score of 37.5, placing it 16 points above the next tier of brands, all of which cluster at 21.2 or below. Azure Container Registry and Amazon ECR share identical composite scores of 21.2, meaning the gap between first and second is larger than the gap between second and tenth. This concentration at the top suggests AI Mode treats Docker Hub as a default reference point, while cloud-native alternatives compete on roughly equal footing beneath it.
A clear divergence between visibility and citation emerges at ranks 4 through 7. Harbor and Quay each hold 25.0 percent visibility but record zero citation, meaning AI Mode names them without linking to their domains. The inverse pattern appears with JFrog Artifactory, which records zero visibility yet a 50.0 percent citation rate, the highest in the category. GitHub Container Registry also shows this reversal, with 12.5 percent visibility against 25.0 percent citation, indicating that being named and being trusted as a source are not equivalent signals here.
Every brand in the top 10 lists Google AI Mode as its top engine, confirming that this category's AI visibility is almost entirely determined by a single engine. The top cited sources in the category are third-party domains including medium.com, distr.sh, daily.dev, peerspot.com, and reddit.com, alongside jfrog.com. This pattern suggests AI Mode anchors on community and review content rather than vendor documentation when generating container registry responses, which partly explains why JFrog earns high citation despite low named visibility.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
