Vaultwarden

Vaultwarden is a lightweight Bitwarden-compatible server you can self-host on a Raspberry Pi. It implements the Bitwarden API in Rust, so all official Bitwarden apps and browser extensions just work — but it runs on a fraction of the resources the official server needs.

Official Bitwarden server is the alternative if you want Microsoft's full-fat .NET stack (needs 2GB+ RAM). 1Password and LastPass are the commercial options. KeePass is the offline-only vault for the truly paranoid.

If you want a proper password manager for your family or small team without paying per-seat fees or trusting a cloud provider, Vaultwarden is the setup. One Docker container, a domain with HTTPS, and you're done. All Bitwarden clients work seamlessly.

The catch: AGPL license, and you're running your own security-critical infrastructure. If your server gets compromised, every password is at risk. You need backups, updates, monitoring, and HTTPS — this isn't set-and-forget. Also, some Bitwarden premium features (like emergency access) may lag behind.
