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

TypeScript

  • Requires build/compilation step; adds complexity to development workflow
  • Performance slower than compiled languages like Rust or Go when running on same hardware
  • Type safety only at compile-time; runtime errors still possible if types are misused
  • JavaScript ecosystem requires understanding both TypeScript and JavaScript
