Like Localshare but works over the internet?
Any recommendations appreciated
Thanks in advance
I don't think the entire service is open source but I really like https://wormhole.app/
pairdrop.net maybe?
It's mainly for local network, but you can do internet transfers.

OnionShare is FOSS and transfers files over TOR network.

SFTP should come with your OS. If you're on *nix, some fiddling around with usergroups is recommended for security reasons.
I wrote my own. I aimed for a different UX than most services. For my use case I have a few devices that I often share files between. So opening the tool on both devices was a bit annoying. Instead you select the file on the first device and you get a push notification on the other. Then the transfer is done over WebRTC (locally if possible). All communication is done end-to-end encrypted and over your browser's push service.

In order of personal preference:
scp (sftp)
rsync/openrsync
nfs
host files on an ftp server with ftpd
hosting files on an http server with httpd

It uses webrtc for P2P connections.
