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

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

Server functions are automatically typed on the client side, enabling IDE autocomplete and type checking when calling server functions from client code.
