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

Visual Studio Code

  • Requires extension installation for language-specific features and tooling
  • Performance can degrade with very large codebases (100,000+ files)
  • Git integration is basic; requires extensions for advanced version control workflows
