Garage receives NLNet grant to work on reliability and performance

2026-04-18T00:00:00+00:00

We are happy to announce that Garage just received a new NLNet grant, to fund work on reliability and performance. In this post we will detail our motivations to make this a priority, and detail the project roadmap for 2026.

Commoning open-source versus growth-hacking open-source

2025-12-08T00:00:00+00:00

Facing recent events in the software-defined storage community, we would like to highlight that not all open-source projects choose an open-source license for the same reasons. Some open-source projects appear to be designed for "growth-hacking" with an "expensive license exit", whereas others are designed as "commons" where all the stakeholders benefiting from the project are taking care of the software while protecting their business or activity. As the creators of Garage, we believe in the latter vision of a "commoning open-source". We made sure, from the beginning, that any new development on Garage will always be released under the same license.

Garage v2.0.0 has been released

2025-06-15T00:00:00+00:00

This week, we released our second major stable version: Garage v2.0.0. The time since the last major release, Garage v1.0.0, has been a bit more than one year. What are the changes warranting a new major release? What is our vision for making cluster administration simpler and more flexible? What will be the release schedule going forward?

Help shape the upcoming administration interface for Garage

2025-03-25T00:00:00+00:00

We released our first major stable version, Garage v1.0, almost a year ago. So what's next for Garage? A graphical user interface for cluster administration! Share your experience and feedback so that we can provide the best possible user experience.

Open letter to the European Commission

2024-07-14T00:00:00+00:00

Deuxfleurs has benefitted multiple times from European grants via the NGI project, for the developpement of Garage and Aerogramme, two pieces of software that we have developped for the needs of our association. Today, these grants are in peril, as the European Commission wishes to finance AI projects instead. We relay and sign an open letter from our friends at petites singularités, that asks that the NGI project be maintained, as it provides great assistance for the development of free software and commons on the Internet.

PhD offering to work on Garage and Distributed Systems

2024-01-10T00:00:00+00:00

Deuxfleurs and IMT Atlantique are partnering to fund a PhD student to work on Garage and distributed systems theory during three years. The recruitment process is open and we are currently looking for candidates. Applications are accepted until Jan 31, 2024. Read for details.

Maintaining read-after-write consistency in all circumstances

2023-12-06T00:00:00+00:00

Garage is a data storage system that is based on CRDTs internally. It does not use a consensus algorithm such as Raft, therefore maintaining consistency in a cluster has to be done by other means. Since its inception, Garage has made use of read and write quorums to guarantee read-after-write consistency, the only consistency guarantee it provides. However, as of Garage v0.9.0, this guarantee is not maintained when the composition of a cluster is updated and data is moved between storage nodes. As part of our current NLnet-funded project, we are developing a solution to this problem. This blog post proposes a high-level overview of the proposed solution.

Thoughts on "Leaderless Consensus"

2023-11-30T00:00:00+00:00

Consensus algorithms such as Raft and Paxos, which are used in many distributed databases, have notoriously unpredictable performance in low-quality networks that suffer from latency, jitter, packet loss and/or unavailable nodes, which is why Garage does not use them and uses only CRDTs. A new paper by Antoniadis et al., Leaderless Consensus</a>, introduces a new category of algorithms that better tolerate the frequent unavailability of a subset of nodes. However, additional research and practical work is required before these results can be put into practice. Read for more details.

Confronting theoretical design with observed performances

2022-09-26T00:00:00+00:00

During the past years, we have thought a lot about possible design decisions and their theoretical trade-offs for Garage. In particular, we pondered the impacts of data structures, networking methods, and scheduling algorithms. Garage worked well enough for our production cluster at Deuxfleurs, but we also knew that people started to experience some unexpected behaviors, which motivated us to start a round of benchmarks and performance measurements to see how Garage behaves compared to our expectations. This post presents some of our first results, which cover 3 aspects of performance: efficient I/O, "myriads of objects", and resiliency, reflecting the high-level properties we are seeking.

We tried IPFS over Garage

2022-07-04T00:00:00+00:00

Once you have spawned your Garage cluster, you might be interested in finding ways to share efficiently your content with the rest of the world, such as by joining federated platforms. In this blog post, we experiment with interconnecting the InterPlanetary File System (IPFS) daemon with Garage. We discuss the different bottlenecks and limitations of the software stack in its current state.

Garage v0.7: Kubernetes and OpenTelemetry

2022-04-04T00:00:00+00:00

We just published Garage v0.7, our second public beta release. In this post, we do a quick tour of its 2 new features: Kubernetes integration and OpenTelemetry support.

Garage will be at FOSDEM'22

2022-02-02T00:00:00+00:00

FOSDEM is an international meeting about Free Software, organized from Brussels. On next Sunday, February 6th, 2022, we will be there to present Garage.

Introducing Garage, our self-hosted distributed object storage solution

2022-02-01T00:00:00+00:00

Deuxfleurs is a non-profit based in France that aims to defend and promote individual freedom and rights on the Internet. In their quest to build a decentralized, resilient self-hosting infrastructure, they have found that currently, existing software is often ill-suited to such a particular deployment scenario. In the context of data storage, Garage was built to provide a highly available data store that exploits redundancy over different geographical locations, and does its best to not be too impacted by network latencies.
