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

Svelte

  • Licensed under the MIT License per svelte.dev; as open source software it has no paid tier or vendor price to compare
  • Svelte is a compiler rather than a runtime library by design, per svelte.dev, so components must be compiled ahead of time and cannot be interpreted directly in the browser without a build step
