Proton Pass has no write-up on Specifiction yet; its figures are above.

Vaultwarden is a free, open-source, unofficial Bitwarden-compatible server written in Rust for self-hosted deployment. It implements the Bitwarden Client API and works with official Bitwarden clients. Personal features include a vault, Send, attachments, website icons, and a personal API key. Organization tools provide collections, password sharing, member roles, groups, event logs, admin password reset, a directory connector, and policies. Listed multi-factor options include authenticator, email, FIDO2 WebAuthn, YubiKey, and Duo, with Emergency Access also included. Vaultwarden supports passkeys, secure sharing, and business admin controls, but not passwordless account login. The project recommends container images from ghcr.io, Docker Hub, or Quay.io. Its web vault requires HTTPS; maintainers recommend a reverse proxy and do not recommend the built-in Rocket HTTPS option. Admin guidance calls for HTTPS and a long random token, with Argon2id storage supported. The project serves self-hosting individuals, families, and small organizations and is not associated with Bitwarden, Inc. The listed plan is free, with no paid plans stated.
