Where each one falls short

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

GitBook

  • Hosted, so you do not own the rendering pipeline and are subject to platform changes
  • Git sync is powerful but conflicts between browser and repository edits are confusing to resolve
  • Pricing scales per user, which gets expensive where many people contribute occasionally
  • Less customisable than a static site generator you control end to end

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
