Open-Source & Self-Hosted Alternatives to Docker Hub & JFrog Artifactory
Docker Hub enforces a hard 100-pull-per-6-hour ceiling on anonymous traffic and a 200-pull-per-6-hour ceiling on free authenticated users; pull a few CI runners too aggressively and your whole build pipeline stalls at 429 Too Many Requests. Free accounts also delete any image that goes 6 months without a push, so long-lived release artifacts vanish unless you upgrade to Pro ($5/user/month). Self-hosting Harbor or Zot behind your own DNS removes the rate ceiling entirely, keeps images as long as your disk holds them, and runs Trivy scanning and Cosign signing out of the box — typically on a €3.79–€15/month Hetzner CX22 or a $6 DigitalOcean droplet. The OCI Distribution API is identical, so `docker pull` and your CI runners keep working unchanged.
Why Migrate Away from Docker Hub & JFrog Artifactory?
Docker Hub rate limits anonymous and team pulls, while JFrog Artifactory costs thousands in enterprise licenses. Self-hosting Harbor or Zot provides an enterprise-grade OCI registry with automated Trivy vulnerability scanning, multi-tenant RBAC, image signing with Cosign/Notary, replication, and unlimited bandwidth on your private servers.
