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

Webpack

  • Complex configuration can be challenging for beginners compared to zero-config alternatives
  • Build times slower than Go-based bundlers like esbuild, especially for large codebases
  • Configuration fragmentation across many plugins increases maintenance burden
