Self-Hosted MinIO Alternatives

Why people look for a MinIO alternative

MinIO earned its position honestly. It implemented the S3 API against local disks in a single binary, which meant a great many applications that refuse to run without an S3 bucket could run on your own hardware for nothing — and that made it the default answer in years of tutorials, compose files and homelab guides. The reason it belongs on a comparison page now is that the repository was archived in April 2026 and is no longer maintained. The README says so in its opening lines, the community edition is distributed as source only, and the commercial product has been renamed AIStor. An existing deployment does not stop working, but starting a new one from MinIO means adopting unmaintained storage — and a compare page that omits this would be repeating the mistake the tutorials made.

Which one should you pick?

Garage is the closest thing to a drop-in successor for a small self-hosted setup: a single dependency-free binary, AGPL-3.0, and replication across zones explicitly designed to run outside datacenters. It is the right pick when you want object storage that is simple to operate and survives a machine being offline. SeaweedFS is the better fit when file count is the problem rather than total bytes — it is built for very large numbers of files with O(1) disk access — and it has the longer track record of the two. Only two maintained S3-compatible servers are listed on this site, which is worth saying plainly: this is a genuinely thin part of the self-hosted ecosystem now, and Ceph, the remaining heavyweight option, is a cluster-scale system with the operational appetite that implies rather than something to install in an evening. Whichever you choose, test a restore before migrating: any of them will accept your data, and only a restore proves it left the old system intact.

Before you migrate

Self-hosting means you are the one who gets paged when something breaks at 11pm. Before committing, be honest about three things:

• Where will it run? A €4/month VPS handles most of these comfortably. A NAS or spare mini PC is even cheaper if you already own one.
• Who backs it up? A self-hosted service with no backup is worse than a cloud service, because at least the cloud service had someone else's redundancy. Set up automated backups before you migrate real data into it.
• How will you reach it remotely? Most people start with a WireGuard or Tailscale tunnel rather than exposing ports directly. That is the right instinct.

Migrating your data

Nearly every MinIO competitor listed above ships an import path — CSV, JSON, or a documented export format. The practical move is to migrate one project or one folder first, run both systems side by side for a week, and only then cut over. Export formats are rarely as clean as the marketing suggests, and it is much easier to notice a broken import on a test set than on five years of records.
