    Project Quay is a self-hosted registry with image scanning, access controls, image builds and mirroring, likewise heavier to deploy than a simple registry.

  • zot

    Self-hosted OCI-native container image registry shipped as a single binary with no dependencies.

    FreeOpen sourcemacOSLinuxSelf-hosted

    zot is a single static binary OCI registry with no external services that runs without root, includes scanning and auth, but offers no replication or web UI as listed.

  • Distribution

    An open-source container registry server for storing and distributing container images and other content.

    FreeOpen sourceLinuxSelf-hosted

    Distribution is a lighter self-hosted registry that runs as a container, but it has no built-in web interface or vulnerability scanning, and access control needs extra setup.

Also worth comparing

These listings name Harbor as their own alternative, so the relationship runs both ways.

  • Clair

    A self-hosted service that statically analyses container images for known vulnerabilities.

    FreeOpen sourceSelf-hosted

    Harbor is a self-hosted container registry with built-in vulnerability scanning, image signing and role-based access control, more than Clair's analysis alone.
