Vaultwarden replaces Bitwarden everywhere you self-host your passwords

Vaultwarden 1.37.0, released July 24, 2026, is a complete Rust rewrite of the Bitwarden server that sips 50 MB of RAM while the official server gulps 2 GB. If your passwords run on your own hardware, you have exactly zero rational reasons left to use the official Bitwarden server.
