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.

There have been several audits done on Vaultwarden of which some are publicly available, read more about it on our Vaultwarden Audits wiki page.
