The shadcn/ui theme generator helps developers create custom themes for shadcn/ui projects quickly and efficiently. It transforms a single primary color into a complete design system with consistent light and dark modes.

The generator allows users to pick a Tailwind color family and shade or input their brand hex code to create a full theme. It provides real-time previews across landing pages, dashboards, and charts with light/dark mode toggling. Users can set body and heading fonts that work well together, choose from radius presets (None, Small, Medium, Large, Full), and copy production-ready CSS variables.

The tool works by starting with a primary color selection, then allowing customization of radius and fonts, followed by live previewing before copying the final theme CSS. This streamlined process eliminates manual theme creation steps.

Benefits include faster theme creation, consistent design across components, and production-ready code output. Use cases include styling shadcn/ui projects, maintaining brand consistency, and accelerating development workflows.

The product targets busy developers working with shadcn/ui who need to create custom themes quickly. It integrates with Tailwind v4 and shadcn/ui workflows, providing CSS variables ready for implementation.
