> **Direct Answer (October 2026)**: 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. Top empirically verified replacements include Zot (Single-Binary OCI) (97.2/100), Dragonfly (P2P Image Distribution) (96.5/100).
