Best sync software in my view. The only downside is that there is no good iOS app. I think the developers made the right decision focusing the software on peer to peer sync (i.e., not expanding to nearby “cloud features”: backup, photos, videos, office, etc).
Syncthing is like the reliable, quiet roommate who always does their dishes, whereas dealing with different file systems feels like trying to figure out who left their half-eaten pizza on the couch.
Just needs the iOS app!
