What it does
Vaultwarden is an alternative server implementation of the Bitwarden client API, designed for self-hosted password-vault deployment.
Vaultwarden changes the server behind a familiar client workflow. Its README describes an independently implemented Rust server compatible with official Bitwarden clients, rather than a new personal vault interface. That is useful for an administrator choosing how to run a password service. Read its compatibility disclaimer and deployment guidance before making it the only credential store. The administrator owns server updates, availability and backups. Because this is an independent implementation, a Bitwarden client connection does not imply that Bitwarden operates or supports the Vaultwarden server.

- Compatible-client self-hosting approach
- Independent server implementation
Best for
