  • Internal Developer Portal requires minimum 20 developer licenses
  • Pipeline execution history retention 6 months (Essentials) vs 25 months as add-on (Enterprise)

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
