What each one is

The product in its own terms, so the numbers below have context.

Astro

Leader

Astro is a web framework that prioritizes performance through server-side rendering and sends minimal JavaScript to browsers. It features an island architecture for selective interactivity, supports all major UI frameworks, and produces zero unnecessary JavaScript by default.

Independently observed

SolidJS

Solid is a JavaScript framework for building interfaces that emits native DOM operations rather than using a virtual abstraction. When your application state changes, it updates only the parts of the interface that depend on that state, avoiding unnecessary component re-renders.
