Where each one falls short

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

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that

  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

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
