Open-source alternative
Replace Docker Hub with Harbor
The best open-source alternative to Docker Hub is Harbor, self-hosted on Railway. A container registry you host. Harbor is Apache-2.0 (CNCF) — Docker Hub without the pull and seat meter.
Estimated save $1,800 a year.

How Docker Hub compares
| Docker Hub | Harbor | |
|---|---|---|
| Pricing model | Per-user subscription plus Hub pull limits | Open-source or fair-code license; you pay the host |
| Hosting | Vendor cloud | Self-hosted on Railway or any VPS |
| Rough monthly cost | Pro $9/user/mo billed yearly ($11 monthly); Team $15/user/mo billed yearly ($16 monthly) source | Hosting only — no SaaS seat meter in this repo |

FAQ
- Is it free?
- The Harbor licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no Docker Hub seat or task bill on this path.
- Can I migrate from Docker Hub?
- Yes. Start with the workflows or data you actually use, then cut over. The Harbor stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Docker Hub links until they expire.
- How do I deploy it?
- Open the Harbor stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: Harbor + Postgres + Redis and a volume (or S3-compatible store) for blobs. No one-click template in this repo yet — Start on Railway. Git hosting can sit on /stacks/forgejo-git.
- What does this replace?
- Docker Hub. The published small-team estimate on this stack is $1,800 a year.
