CallFS

Self-hosted REST API file storage server turning local disks and S3 into one distributed filesystem.

Webfree

CallFS is a self-hosted, open-source file storage server that combines local disks and S3-compatible object stores into a single distributed filesystem accessible over a REST API, with erasure coding for fault tolerance, owner-based access control, and secure expiring download links. It scales horizontally across a cluster of nodes. It's aimed at developers building file management services, media pipelines, or backup systems who want an HTTP-based alternative to fragile NFS mounts.
