Bitwarden lite self-host deployment, formerly unified, is now generally available! This self-host option is a more lightweight and flexible deployment alternative, ideal for homelab enthusiasts and community members who want to get started quickly with self-hosting Bitwarden. With the release of general availability, Bitwarden lite users can benefit from enhanced performance and reliability.
Seems to be an official alternative to Vaultwarden
You are missing the point; the original comment was about not having the keys to restore the (I assume) encrypted backups. With Bitwarden you can still access the vault even if the server is offline/lost. It’s not a replacement for a backup strategy.
