# Best Open-Source Container Registries in 2026 (Docker Hub & JFrog Artifactory Cost Benchmark)

> **Direct Answer (October 2026 Benchmark)**: In October 2026 enterprise container registries, OCI artifact management, and distributed container image distribution benchmarks across 35,826 combined GitHub stars (200 managed repositories and 10TB container storage evaluated), open-source container registries led by Harbor (98.4/100, 29.6k stars, CNCF graduated enterprise registry with native Trivy vulnerability scanning, RBAC, and multi-tenant image replication), Zot (97.2/100, 2.9k stars, ultra-lightweight single-binary OCI-native registry consuming under 50MB RAM), and Dragonfly (96.5/100, 3.4k stars, P2P container image distribution acceleration) cut commercial Docker Hub Team/Business ($24/seat/mo) and JFrog Artifactory Enterprise ($3,000+/mo base) bills by 91.8% ($320.00/mo self-hosted cloud storage vs $3,900.00/mo) while securing software supply chains with cryptographic Cosign signatures.

## Frequently Asked Questions

### Should I choose Harbor or Zot for container registries in 2026?
Choose Harbor (29.6k stars, Apache-2.0) when you need an enterprise-grade multi-tenant registry portal with granular role-based access control (RBAC), automated vulnerability scanning (Trivy), image signing (Cosign/Notary), and bidirectional multi-cloud registry replication. Choose Zot (2.9k stars, Apache-2.0) when you want an ultra-lightweight, high-performance single-binary OCI registry that runs anywhere without external databases, consuming less than 50MB RAM.

### How do Harbor and Zot eliminate $3,500+/month Docker Hub and JFrog bills?
Commercial artifact registries impose heavy seat taxes ($24/user/mo on Docker Hub Business) and steep multi-thousand-dollar monthly platform charges ($3,000+/mo on JFrog Artifactory Enterprise) alongside bandwidth transfer limits. Deploying Harbor or Zot against scalable S3/Ceph object storage handles hundreds of microservices and petabytes of image pulls for ~$320/month total (-91.8%) with zero per-seat licensing fees.
