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

Express.js

  • Governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare
  • Express.js provides only a thin layer of fundamental routing features by its own description, requiring separate middleware modules for functionality like body parsing, sessions or authentication
