Seafile is not FOSS, as I understand it. But I tried it anyway, since I also found Nextcloud bloated.
In the end I went back to the purest strategy of all: peer-to-peer. My files are synced between devices over the local network using ssh
, rsync
and unison
and never touch an internet server.
If you don’t mind going full back-to-basics, you can do this with standard command-line tools and no cloud server. Contrary to popular wisdom, a server is not necessary to sync files between a computer and a mobile device.
I use
ssh
andunison
over wifi hotspot, no cable required. Works fine though it does require a button to be pressed. It doesn’t sync constantly in the background. Personally, after many years of doing that, I decided that it was an anti-feature.
