Where each one falls short

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

Infisical

  • Free tier limited to 5 identities, suitable only for small teams or evaluation
  • Pricing tiers are per-identity, which scales costs with team size
  • Certificate management requires Enterprise plan for advanced features like wildcards
  • Privileged access tier is separate billing from secrets management

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
