What each one is

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

Preact

Leader

A minimal virtual DOM library that provides a React-compatible API with significantly reduced file size. Preact delivers performance-focused component development without the overhead of traditional frameworks.

Independently observed

SolidJS

A JavaScript library for constructing user interfaces using fine-grained reactivity, updating only what changes rather than diffing virtual DOMs. Emphasizes performance through reactive primitives and supports modern patterns like async handling, server-side rendering, hydration, and streaming.
