Side by side
A single-file Python file server with resumable uploads, deduplication, thumbnails, media indexing and access over HTTP, WebDAV, SFTP, FTP, TFTP and SMB.
Continuous peer-to-peer file synchronisation between your own devices, encrypted, with no central server.
Mostly one developer's work, and its many protocols and options need careful permission configuration before exposing it to the internet.
It is sync, not backup, so deletions and corruption propagate, and the official Android app has been discontinued in favour of community forks.
