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
Ruby on Rails
- Licensed under the MIT License per rubyonrails.org; as open source software it has no paid tier or vendor price to compare
- The framework is Ruby-only by design, per rubyonrails.org's own description of its convention over configuration approach, requiring the Ruby runtime rather than supporting alternate languages
