How does GitHub Container Registry compare to Amazon ECR?

GHCR is tightly integrated with GitHub Actions and repository permissions, making it natural for GitHub-native CI/CD pipelines. ECR integrates deeply with AWS services (ECS, EKS, CodePipeline). GHCR has a generous free tier for public images. ECR offers more granular IAM policies and native AWS networking for pull performance.

What is the best self-hosted alternative to Amazon ECR?

Harbor is the CNCF-graduated open-source standard for self-hosted container registries. It provides vulnerability scanning via Trivy, LDAP/AD integration, replication policies, and Helm chart support. Quay.io is also available as a self-hosted option via Project Quay.

Do ECR alternatives support OCI artifact standards beyond Docker images?

Yes. Google Artifact Registry, JFrog Artifactory, Harbor, and Quay all support OCI artifacts including Helm charts, WASM modules, and signed software supply chain artifacts via Cosign and Sigstore. Azure Container Registry also supports OCI artifact storage through its ORAS integration.
