## What it is
A fine-grained reactive DOM rendering runtime for JavaScript libraries that use signals or observables instead of a virtual DOM. It provides the core rendering engine behind libraries like Solid, with companion JSX Babel plugin, tagged template literal, and HyperScript APIs.

## Use cases
- build a custom reactive UI library with fine-grained updates
- render DOM without a virtual DOM for maximum performance
- add JSX rendering to an observable library like MobX or Knockout
- generate a tree-shakeable reactive runtime for a signals library
- benchmark fine-grained DOM update performance

## When to choose
- you are authoring a reactive frontend library and need a performant DOM renderer
- you want signal-based fine-grained change detection instead of re-rendering
- you need top-tier js-framework-benchmark style DOM performance

## When to avoid
- you are building a typical application and should use Solid or another framework directly
- you rely on a virtual DOM ecosystem like React
- you need a batteries-included UI framework with routing and state management
