Melt UI

Melt UI is an open-source headless component builder library created specifically for the Svelte ecosystem, designed to help developers construct accessible and highly customizable user interface components. Rather than providing fully styled widgets, the library focuses on supplying the behavioral logic and accessibility patterns needed to build UI components while allowing developers to control the visual appearance. Melt UI introduces a builder-based architecture where component logic is encapsulated in reusable primitives that can be attached to any HTML element or custom component. The project strongly emphasizes accessibility and follows WAI-ARIA standards to ensure consistent keyboard navigation and screen reader compatibility. It also integrates seamlessly with SvelteKit and TypeScript, making it suitable for modern web development workflows.

Headless component builders designed for Svelte applications
Builder-pattern architecture for flexible component composition
