Where each one falls short

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

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Vue.js

  • Multiple state management options (Vuex, Pinia, plain reactive) can confuse developers without clear guidance
  • Reactive system has limitations detecting property additions or deletions in objects, requiring explicit methods
  • Official documentation assumes prior experience, making advanced concepts harder for newcomers to learn
