I have been self-hosting Vaultwarden for a few months and it has been great. But this news still worries me because Vaultwarden still relies on open-source Bitwarden clients and sounds like those could be on the chopping board anytime soon.

Separately, I don't know if there is a self-hostable password manager which allows easy family sharing. (KeepassXC won't work, I believe, because the whole vault is a single file.)
