1Password

1Password is a polished password manager used by millions of individuals and businesses. At $7.99/user/month for Teams, it's not cheap for larger organizations. The open source alternatives — Bitwarden and Vaultwarden — provide comparable password management with significantly more flexibility.

Bitwarden is the most complete open source password manager — it has browser extensions for every major browser, desktop apps, mobile apps, a web vault, CLI, and organization features for team password sharing. Vaultwarden is a lightweight, community-built implementation of the Bitwarden server API, designed for self-hosting on minimal hardware — it's compatible with all official Bitwarden client apps while using far less resources than the official Bitwarden server.

For businesses, the self-hosting value is clear. Password vaults contain the most sensitive data in any organization — master passwords, API keys, credentials for every service. Self-hosted Bitwarden or Vaultwarden means this data never leaves your infrastructure. Even if Bitwarden Cloud is trustworthy, the defense-in-depth approach of keeping credentials on your own servers adds a layer of security.

Vaultwarden is particularly popular for home labs and small teams — it runs in a single Docker container with SQLite, requiring minimal resources (256MB RAM) while supporting all Bitwarden client features including organizations, send, and attachments.
