Where each one falls short

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

Docusaurus

  • Customisation past the config file assumes React knowledge, which not every docs team has
  • Build times grow noticeably on very large sites, particularly with many versions and locales
  • Major version upgrades have required real migration work rather than a dependency bump
  • It generates a static site, so anything dynamic — gated content, per-user docs — needs a separate solution

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits
