Vaultwarden (formerly Bitwarden_RS) is a lightweight, self-hosted Bitwarden-compatible password management server written in Rust. It has low resource consumption, is suitable for single-machine deployment, and is ideal for individuals or small teams. I mainly use it to fill the gaps that KeePassXC cannot cover. Its multi-device synchronization function is very suitable for local area networks. For example, if you save a password on your home computer, you can synchronize it to your phone or tablet on the same Wi-Fi network through Vaultwarden, without having to go through the public network.
