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
Node.js
- Slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
- Requires separate setup for TypeScript support unlike Deno which treats TypeScript as native
- Larger memory footprint on startup compared to lightweight alternatives like Deno
