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

Violentmonkey

  • Smaller script ecosystem compared to Tampermonkey which has larger user base and more available scripts
  • Less marketing and visibility results in lower adoption compared to more widely-known alternatives
  • Community maintenance model means slower feature development compared to commercial alternatives
