    ARK

    ARK

    Unstyled, accessible UI components for your design System

    ...The project focuses on separating component behavior from visual styling so developers can implement their own design language without being constrained by predefined styles. Built on top of Zag.js state machines, Ark delivers predictable and robust component logic that works consistently across multiple JavaScript frameworks. It supports React, Solid, Vue, and Svelte, enabling developers to share component behavior across ecosystems while maintaining framework-specific implementations. Because the components are headless, developers bring their own CSS frameworks, styling solutions, or design tokens, which makes the library highly adaptable for custom UI systems.
