## What it is
Kobalte is a UI toolkit of unstyled, accessible components and primitives for building web apps and design systems with SolidJS. It handles WAI-ARIA accessibility details like ARIA attributes, focus management, and keyboard navigation while letting you bring any styling solution.

## Use cases
- build accessible components in SolidJS
- create a custom design system with unstyled primitives
- add accessible popovers, dialogs, and accordions to a Solid app
- style component states with Tailwind data-attribute modifiers
- handle keyboard navigation and focus management for custom widgets
- use accessible UI components with SolidStart SSR

## When to choose
- you use SolidJS and need accessible, headless UI primitives
- you want full styling control with Tailwind, CSS-in-JS, or vanilla CSS
- you are building a design system on WAI-ARIA patterns

## When to avoid
- you use React or Vue instead of SolidJS
- you want pre-styled, ready-made components out of the box
