Sass

  • Licensed under the MIT License per sass-lang.com; as open source software it has no paid tier or vendor price to compare
  • The LibSass and Ruby Sass implementations are marked deprecated on sass-lang.com, leaving Dart Sass as the only actively maintained compiler

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

So you own the code. Components are copied into your project, which makes customisation trivial — at the cost of receiving no automatic updates.
