Where each one falls short

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

Caddy

  • Smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • Adding plugins means rebuilding the binary rather than loading a module
  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments

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
