The shadcn/ui theme generator is designed to help developers create a shadcn/ui theme quickly by selecting visual preferences. It transforms a single primary color into a complete light and dark theme system that maintains consistency across components.

The tool allows users to pick a Tailwind color and shade or input a custom brand hex code to generate the full theme. Users can set body and heading fonts that work well together, with options to link them for consistency or unlink for suggested pairings. Radius presets (None, Small, Medium, Large, Full) ensure consistent border radii across all components up to 1.5rem. A real-time preview shows changes instantly on landing pages, dashboards, and charts with light/dark mode toggling. The generator provides one-click copying of theme CSS, randomization for inspiration, reset to defaults, and integration with the shadcn/ui Figma kit.

The process begins by selecting one primary color from Tailwind families or a custom hex. Next, users choose border radius presets and font pairings for body and heading text. The theme updates live across multiple preview screens as adjustments are made.

Benefits include rapid theme creation for shadcn/ui projects, ensuring visual consistency with production-ready CSS variables. Use cases involve styling shadcn/ui components efficiently for web applications, dashboards, and landing pages.

The tool targets busy developers working with shadcn/ui and Tailwind CSS, supporting frameworks like Next.js or Astro. It integrates with the shadcn/ui Figma kit for design synchronization.
