Garage: sovereignty score and 8 European alternatives

Garage is an open-source, S3-compatible object store for small self-hosted installations spread across several sites. The software is a single binary without external dependencies and runs on Linux. Each piece of data is replicated across several zones. Applications that use the Amazon S3 API, such as Nextcloud and Matrix, can connect to it directly. The software is designed to run on your own infrastructure.

Garage is built by Deuxfleurs, a French association that runs small-scale self-hosted services on machines in France and Belgium. The source code is published on GitHub and on Deuxfleurs' own Git server under the GNU Affero General Public License v3 (AGPLv3). Because the software is open source and runs on your own infrastructure, the operator keeps control over where data sits and which keys are used. That makes Garage relevant for European organisations that want object storage without a US cloud provider in the chain. GDPR compliance rests with whoever operates the storage.

Why digital sovereignty matters with Garage

Garage is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Garage scores best on data residency.

Garage is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Garage together with your other vendors and gives a total score, a heatmap and the main risk drivers.
