Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

Tailwind CSS

  • HTML markup becomes verbose with many utility classes (class="flex items-center justify-between bg-gradient-to-r..."); readability challenges for complex layouts
  • 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
