+1 for Syncthing. I've been running it for years, after my student discount for Dropbox expired (Google drive and OneDrive were just getting traction at the time).
The mobile experience last I tried was pretty rough though. I don't really need my files on my phone and I have a web interface on my home server I can use to grab them in a pinch, but it's something to keep in mind.
