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

RAD Studio

  • Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
  • Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
  • The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription
