#s3 + #open-source

CloudServer (formerly S3 Server) is an open-source object storage project to enable on-premises S3-based application development and data deployment choice.

This is a Container Storage Interface (CSI) for S3 (or S3 compatible) storage. This can dynamically allocate buckets and mount them via a fuse mount into any container.

GeeseFS allows you to mount an S3 bucket as a file system. GeeseFS is a high-performance, POSIX-ish S3 (Yandex, Amazon) file system written in Go

An open-source distributed object storage service tailored for self-hosting

Garage implements the Amazon S3 API and thus is already compatible with many applications.

The main goal of Garage is to provide an object storage service that is compatible with the S3 API from Amazon Web Services. We try to adhere as strictly as possible to the semantics of the API as implemented by Amazon and other vendors such as Minio or CEPH.

In December 2025, MinIO officially entered “maintenance mode” for its open-source edition, effectively ending active development. Combined with earlier moves like removing the admin UI, discontinuing Docker images, and pushing users toward their $96,000+ AIStor paid product, the writing was on the wall: MinIO’s open-source days were over.

Garage: What I chose. Lightweight, Rust-based, genuinely open source. SeaweedFS: Go-based, active development, designed for large-scale deployments but works at small scale. Ceph RGW: If you’re already running Ceph, the RADOS Gateway provides S3 compatibility.
