   GPT #1Claude #1Gemini #2Grok #2

   Best default for production AWS workloads: deep IAM integration, EKS/ECS fit, strong private networking, lifecycle policies, vulnerability scanning, cross-region/account replication, pull-through cache, OCI artifact support, and very high operational reliability

   To stay #1 Make multicloud and non-AWS developer workflows as polished as its AWS-native experience

2. 2
   GitHub Container Registryincumbent—13 pts

   GPT #4Claude #2Gemini #1Grok #4

   Seamless integration with GitHub Actions workflows, fine-grained access controls mapped directly to repository permissions, and a generous free tier for public images.

   To rank higher Provide natively integrated, out-of-the-box vulnerability scanning and automated remediation dashboards.

3. 3
   Harborincumbent—10 pts

   GPT —Claude #3Gemini #4Grok #1

   CNCF graduated open-source leader with built-in Trivy scanning, SBOM generation, replication, RBAC, quotas, signing support and strong Kubernetes/air-gapped capabilities; highest PeerSpot mindshare and ratings in 2026 for enterprise control without vendor lock-in.

   To rank higher Simplify initial deployment and day-2 operations (Helm/K8s complexity and UI) to broaden adoption beyond platform teams.

4. 4
   Google Artifact Registryincumbent▲19 pts

   GPT #2Claude #4Gemini #3Grok —

   Excellent modern registry for GCP and Kubernetes teams: Docker plus multi-package support, strong IAM, vulnerability analysis, remote and virtual repositories, VPC Service Controls, Cloud Build/GKE/Cloud Run integration, and image streaming/prewarming advantages

   To rank higher Improve cross-cloud adoption and ecosystem familiarity outside Google Cloud

5. 5
   Azure Container Registryincumbent▲14 pts

   GPT #3Claude —Gemini #5Grok —

   Strongest choice for Azure shops: AKS/Entra ID/RBAC integration, private endpoints, geo-replication, Defender scanning, OCI/Helm support, and ACR Tasks for cloud builds, base-image rebuilds, and patch automation

   To rank higher Simplify pricing, tiers, and advanced security so it feels less Azure-enterprise-heavy

6. 6
   JFrog Artifactoryincumbent▲13 pts

   GPT #5Claude #5Gemini —Grok #5

   Best broad enterprise artifact platform when containers are one part of a larger supply chain: strong Docker/OCI support, mature permissions, replication, metadata, promotion workflows, Xray security integration, and multi-format package governance

   To rank higher Make setup, administration, and pricing much simpler for teams that only need a container registry

7. 7
   Docker Hubincumbent▼33 pts

   GPT —Claude —Gemini —Grok #3

   Still the dominant public registry with unmatched catalog of official/verified images, seamless Docker CLI integration and automated builds; powers discovery and distribution for vast majority of container workloads and OSS projects.

   To rank higher Eliminate aggressive free-tier rate limits and expand included private repos/scanning to stop driving serious users to paid plans or mirrors.
