TanStack Start

  • Still in Release Candidate status, not yet production stable
  • Smaller community compared to Next.js with less third-party support
  • Documentation not as comprehensive as more established frameworks
  • Less mature ecosystem for edge deployment compared to specialized frameworks

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
