Comparisons anchored on Harbor, the CNCF graduated Apache-2.0 registry for container images, Helm charts and OCI artifacts, against other self-hosted registries.
Harbor's full registry with projects, RBAC, Trivy scanning, replication and proxy cache against the bare CNCF Distribution registry with htpasswd or token auth: what each needs to run, security controls, storage backends and when the simple registry is enough.
Two full-featured open-source registries compared: Harbor (CNCF) against Project Quay, the upstream of Red Hat Quay, on vulnerability scanning with Trivy or Clair, geo-replication, access control, deployment on Kubernetes and commercial support.
