Why it's listed

Vaultwarden reimplements the Bitwarden server API in Rust, cutting the official stack's resource needs by an order of magnitude — it idles around 50MB of RAM on a Raspberry Pi while serving every Bitwarden client. End-to-end encryption means the server never sees your secrets. Community-maintained, AGPL, and the single most-recommended first self-hosting project for good reason.
