Garage vs SeaweedFS
Both are alternatives to Amazon S3. Here's how they stack up — verified facts, no spin.
Also searched as SeaweedFS vs Garage — same comparison, one verdict.
Garage and SeaweedFS are closely matched on ownership (95 vs 93) — this one comes down to pricing and to which trade-offs below you can live with.
Garage
Object storage for geographically scattered, unreliable hardware.
Garage is a lightweight S3-compatible store built by Deuxfleurs for a case the others handle badly: nodes spread across different homes and cities on ordinary connections, where latency is high and machines come and go. It is deliberately small, has no single point of failure, and runs on hardware you would not consider adequate for object storage. AGPL-3.0. It is the most niche entry here and it earns its place by being the honest answer for community and self-hosted infrastructure rather than a datacentre.
SeaweedFS
Built for billions of small files, where most object stores struggle.
SeaweedFS is a distributed file and object store designed around a specific weakness in the others: enormous numbers of small files. Its architecture keeps metadata lookups fast where conventional object stores slow down, which makes it a strong fit for image, thumbnail and document workloads at scale. Apache-2.0, around 34k stars, with an S3-compatible gateway and tiered storage to cloud back-ends. It is less known than MinIO and that is the main caution — fewer worked examples when something goes wrong.

Garage edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Garage
Strengths
- +Built for geographically distributed nodes on unreliable links
- +Extremely light — runs on hardware other stores refuse
- +No single point of failure by design
- +AGPL-3.0 with genuinely community governance
Trade-offs
- −Smallest project here by a wide margin
- −Fewer S3 API features implemented than MinIO
- −Not aimed at high-throughput single-datacentre workloads
- −Very small community if you get stuck
SeaweedFS
Strengths
- +Handles billions of small files where other object stores degrade
- +Apache-2.0 — more permissive than MinIO's AGPL
- +S3-compatible gateway plus a real filesystem interface
- +Tiered storage to cloud back-ends for cold data
Trade-offs
- −Smaller community and fewer worked examples than MinIO
- −More moving parts — master, volume and filer servers
- −Documentation is thinner
- −Less battle-tested at enterprise scale
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Garage
if a lower exit cost matters more to you than any single feature, and built for geographically distributed nodes on unreliable links.
Choose SeaweedFS
if handles billions of small files where other object stores degrade.
Neither, yet
if both carry a real cost you should weigh first — smallest project here by a wide margin, and smaller community and fewer worked examples than MinIO. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Garage vs SeaweedFS — common questions
Is Garage a better fit than SeaweedFS for object storage?
It depends on what you are optimising for, and the honest split is this: Garage scores 95 to SeaweedFS's 93 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. SeaweedFS earns its place on a different axis — handles billions of small files where other object stores degrade. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Garage keeps its data local or in open formats, so leaving is an export rather than a negotiation. SeaweedFS is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Garage or SeaweedFS?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Garage and SeaweedFS both alternatives to Amazon S3?
Yes — both appear in our Amazon S3 comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Amazon S3 and now choosing between the two replacements, which is a narrower and much easier question.
