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

Remix

  • Different mental model than traditional React SPAs requires learning curve
  • Smaller ecosystem compared to Next.js despite Shopify backing
  • SSR adds server-side complexity for teams preferring client-first architecture
  • Form-first approach not optimal for highly interactive UI-heavy applications
