The short version
- 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; Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration

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
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
