  • Limited animation library compared to dedicated animation tools (Framer Motion); complex transitions require custom CSS or JavaScript
  • Customisation beyond configuration requires editing generated CSS or writing custom utilities; not as flexible as hand-written CSS for unique designs
  • Tailwind Plus (components, templates) is paid; developers seeking production-ready component libraries must purchase or build custom
