Astro 5 vs Hono + htmx
Real-world performance comparison based on identical SaaS dashboard implementations.
Astro 5
VPS
The web framework for content-driven websites. Astro's revolutionary Islands architecture ships zero JavaScript by default—interactive components hydrate independently only where needed, dramatically reducing bundle sizes. Astro 5 introduces Content Layer for type-safe content collections, Server Islands for mixing static and dynamic content, and improved build performance. The framework is UI-agnostic: use React, Vue, Svelte, Solid, or vanilla JS components in the same project. Perfect for marketing sites, documentation, blogs, and any content-heavy application where performance matters. Astro consistently achieves perfect Lighthouse scores with minimal effort.
Hono + htmx
VPS (Deno)
Ultrafast web framework meets hypermedia, running on Deno. Hono is a tiny (14KB), ultrafast web framework that runs everywhere. This variant uses Deno runtime for secure-by-default execution and native TypeScript support. Combined with htmx for HTML-over-the-wire interactivity, Hono on Deno produces minimal bundles while maintaining full interactivity—all without a JavaScript framework.
