Where each one falls short

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

Astro

  • Limited to static site generation and server-side rendering; real-time applications requiring constant client-server communication are unsuitable
  • Smaller ecosystem compared to Next.js; fewer third-party component libraries and integrations readily available
  • Build time increases with large content volumes (1,000+ pages); incremental builds not yet as optimised as Gatsby or Next.js
  • API routes and serverless functions are less mature than Next.js; complex backend integrations require additional tooling

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
