Vaultwarden [selfhost]
Vaultwarden is an unofficial Bitwarden server implementation written in Rust. It is compatible with the official #Bitwarden clients, and is ideal for #self-hosted deployments where running the official resource-heavy service is undesirable.
#Vaultwarden is targeted towards individuals, families, and smaller organizations.
Development of features that are mainly useful to larger organizations (e.g., single sign-on, directory syncing, etc.) is not a priority, though high-quality PRs that implement such features would be welcome.
