Moving to vaultwarden (the open bitwarden server implementation) was also really easy. Just installed the package in Arch, setup the vhost in nginx, put the vhost into my local DNS and slightly adjusted the vaultwarden config file. Now I use bitwarden clients everywhere and point them to my server.

Since I don't feel 100% comfortable having my self hosted things on a public IP, I put it only on my LAN. For remote access (e.g. phone) I use wireguard.
