Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

authentik

  • Smaller project than Keycloak, with a correspondingly smaller community and fewer integration guides
  • The flow model is flexible but conceptually unfamiliar, and simple setups can feel over-abstracted
  • Enterprise support and some governance features sit behind the paid tier
  • Self-hosted identity is still yours to secure, patch and keep available

Bitwarden

  • The integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month
  • Free accounts can share vault items with one other Bitwarden user and no more
  • File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan
  • Two-step login accepts up to 10 hardware security keys per account
  • The Families plan is capped at 6 people, so a seventh member means moving to a Teams subscription at $4 per user per month
