- Only Astro has a free tier, so it costs nothing to try first.
- Each has a real cost: Astro limited to static site generation and server-side rendering; real-time applications requiring constant client-server communication are unsuitable; 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

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
