Where each one falls short

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

shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

SonarQube

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