HS5 is a high-performance, self-hosted object storage service designed to scale up on a single node.

The software provides an Amazon S3-compatible API alongside a web interface for managing buckets, users and access permissions. It separates object metadata from the stored data, allowing metadata to reside on fast storage while object contents are kept on higher-capacity disks.

This is free and open source software.
