Where each one falls short

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

Authelia

  • Depends on a reverse proxy: it is not a standalone identity provider
  • Configuration is YAML-first with no administrative interface, so changes mean editing files
  • Not a full IAM: user management, provisioning and federation are limited compared with Keycloak
  • Scales poorly as an organisation-wide identity solution, which is not its target

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that
  • Team plan pricing ($21/user/mo) adds cost for large teams
  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

Answered from the vendors’ own pages

Authelia: Does Authelia need a reverse proxy?

Yes. It integrates through forward authentication with Nginx, Traefik, Caddy or HAProxy rather than sitting in front of traffic itself.

Doppler: What is the difference between Team and Enterprise plans?

Team plan ($21/user/mo) includes SAML SSO, role-based access controls, and 90-day logs. Enterprise adds custom deployment options, unlimited config syncs, 99.95% SLA, and a dedicated account manager.

Authelia: Authelia or Keycloak?

Authelia is far lighter and aimed at protecting self-hosted services behind a proxy. Keycloak is a full identity and access management platform, and much more to run.

Doppler: Can I rotate secrets automatically?

Yes, both Team and Enterprise plans support automatic secret rotation. Developer tier supports manual rotation only.
