Vaultwarden
github.com/dani-garcia/vaultwarden
Lightweight, unofficial self-hosted server compatible with Bitwarden clients — run your own password manager backend instead of paying for 1Password.
Why it is useful
Vaultwarden implements the Bitwarden API in Rust with a much smaller resource footprint than Bitwarden's official server, making it practical to self-host on cheap hardware. It works with all official Bitwarden apps and browser extensions, so users get the same client experience while keeping the vault entirely on their own server.
