What is the selling point over the very mature Syncthing? I’ve been using that for this use case for many years, with the additional benefit of also being able to sync it to my server, having a UI and being in all package managers already.
being fr, i never even knew about syncthing until now. it's (clearly) a lot better, but again, the reason I made this is because of my school's software whitelist. they only allow certain apps to run on my laptop, one of them being python due to out compsci class. since then, I've been using it to get around whitelists and make my own stuff.
this allows me to sync up me and my friend's stuff (like projects, etc.) while we're in school and not have to worry about the whitelist :)
