- Smaller community means fewer tutorials and third-party libraries
- Performance may suffer in highly interactive applications with frequent state updates
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
