Been using syncthing for a year now and works great for syncing between devices. But i miss file sharing with family members that nextcloud allowed me to do. Yet i left ut because it was too bloated and every update at the time broke my instalkation. Is there something a mature and specialised as syncthing but that allows sharing between accounts?
I haven’t used it but I heard a lot of good things about copyparty.
Also, I don’t want to be that guy, but were you running Nextcloud in a container or bare metal? Nextcloud pissed me off too, but now I’m running NextcloudPi in an LXC and have had no issues so far.
