Vaultwarden

Vaultwarden is an unofficial Bitwarden-compatible server implementation written in Rust, designed for self-hosting on resource-constrained hardware. Originally known as bitwarden_rs, it provides full compatibility with official Bitwarden clients while consuming a fraction of the resources. Popular among home labs, small businesses, and privacy-focused organizations, Vaultwarden supports two-factor authentication, organizations, attachments, and admin interfaces. The project is community-driven and widely deployed via Docker. It is ideal for technical teams who want Bitwarden features without the official server overhead or costs.
