Cloudreve

A self-hosted file management and sharing system that puts a polished web drive in front of local disks or external storage providers. It supports local storage, S3 compatible object stores, OneDrive and other backends, with direct client to storage transfers, WebDAV access, user groups, expiring share links, archive handling and in-browser preview of images, video and documents.

People use it as a private Dropbox replacement for teams that need shared folders, links that expire and mobile access to storage they already own.

Hosting it yourself keeps the file index and the storage credentials on your servers, and the whole dataset can be captured with ordinary filesystem or object storage snapshots.
