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

Remix

  • Different mental model than traditional React SPAs requires learning curve
  • Smaller ecosystem compared to Next.js despite Shopify backing
  • SSR adds server-side complexity for teams preferring client-first architecture
  • Form-first approach not optimal for highly interactive UI-heavy applications
