Developed with the blessing of shadcn's original creator, this open-source project has garnered over 7,500 GitHub stars and provides Svelte developers with a comprehensive collection of beautifully designed UI components built with Tailwind CSS and Svelte's reactive primitives. The library follows the same philosophy as shadcn/ui, allowing developers to copy components directly into their Svelte or SvelteKit applications rather than installing them as dependencies, giving teams complete control to customize, modify, and own their component code. Each component is crafted with accessibility as a priority, supports Svelte's reactivity system, and integrates seamlessly with Tailwind CSS for easy styling and theming. Perfect for Svelte and SvelteKit projects, this library provides everything from basic UI elements like buttons and inputs to complex components like data tables, command palettes, and dialog systems, enabling developers to build their own component library with consistent, production-ready building blocks designed specifically for the Svelte framework.
