Explore the 23rd UI Component Registry

23rd is a free registry of shadcn/ui components for React and Svelte 5. Install individual components through the shadcn CLI, then customize their source in your project.

The collection includes backgrounds, shaders, footers, pages, and interactive elements. A few examples: an ASCII wordmark that scatters and falls, a shader sky with clear or rainy weather, and a 404 page with a fireball cursor.
