I moved to Vaultwarden from Keepass with Nextcloud. I used that for a long time, but noticed severe syncing issues at some point. And because the sync was constantly overwriting the full kdbx container in the cloud from different devices that I’m using at the same time, it seemed very unsafe and hard to troubleshoot. I like KeepassXC and KeepassDX a lot more than the Bitwarden apps, but the more stable, built-in sync is more important for me.
