ZenoRegistry review
A focused, S3-backed registry for teams that want infrastructure and data control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ZenoRegistry is a self-hosted container registry from Citium Software for internal platform teams and organizations that want control over infrastructure and data. It runs as a single Go binary with an embedded web administration dashboard, PostgreSQL metadata storage, and S3-compatible blob storage. The OCI Distribution API supports pushing, pulling, tag listing, catalog access, chunked uploads, blob mounts, and deletion. Multi-architecture images and OCI image indexes extend its fit for teams managing varied deployment targets.
Its strongest case is infrastructure flexibility. ZenoRegistry supports AWS S3, MinIO, Ceph, DigitalOcean Spaces, and Scaleway Object Storage, while Docker, Podman, and nerdctl provide familiar client options. Keycloak, Microsoft Entra ID, Google Workspace, Authentik, and Okta connect identity workflows through OIDC single sign-on. Argo CD and Flux integrations also suit Kubernetes-oriented delivery processes. Native TLS, a Kubernetes health endpoint, and graceful shutdown address practical deployment requirements without changing the product’s focused registry role.
Security and governance features add depth beyond basic image storage. Repository-scoped pull, push, and admin roles limit access by repository, and per-repository retention policies include dry-run previews before cleanup. Cosign-aware handling covers signatures, attestations, and SBOMs, giving platform teams a place to manage related supply-chain artifacts. According to Citium Software, prospective customers can discuss a demo, managed deployment, or self-hosted licence directly. ZenoRegistry fits teams prepared to operate their own registry and choose their storage layer; organizations seeking a broadly managed service or a simpler hosted purchasing path should consider an alternative.
