## What it is
Melt UI is a collection of headless, accessible component builders for Svelte that provide behavior and WAI-ARIA compliance without any styling. It lets developers attach unstyled builders to their own elements to build custom design systems and web apps.

## Use cases
- build accessible dropdowns and dialogs in Svelte
- create a custom design system with unstyled components
- add WAI-ARIA compliant collapsible or accordion behavior
- build SvelteKit apps with accessible UI primitives
- style my own components while reusing headless behavior logic

## When to choose
- you use Svelte or SvelteKit and want full styling control
- accessibility and WAI-ARIA compliance are priorities
- you want to build your own design system on headless primitives

## When to avoid
- you want pre-styled, ready-made components out of the box
- you are not using Svelte
- you need a full UI kit with themes and visual defaults

## Facets
- artifact type: library
- maturity: active
- function: ui-components, frontend-framework, accessibility
- domain: web-development, frontend, accessibility
- platform: cross-platform
