Shadcn Theme Editor

Built with Next.js, React, TypeScript, and Tailwind CSS, this component allows developers and designers to interactively adjust all theme tokens, preview changes in real-time across light and dark modes, and export ready-to-use CSS configurations. The editor features interactive color pickers for all shadcn/ui theme tokens including background, foreground, primary, secondary, accent, destructive, and border colors, live preview showing how components look with the selected theme applied, automatic HSL to CSS variable conversion eliminating manual color format calculations, one-click copying of generated CSS for immediate integration into projects, preset theme templates to jumpstart customization from popular color schemes, and accessibility contrast checking to ensure color combinations meet WCAG standards. The interface organizes theme tokens by their semantic purpose, making it clear which colors affect buttons versus backgrounds versus text, helping developers understand the shadcn/ui theming system while customizing it.

This tool is invaluable for designers creating custom brand themes without CSS expertise, developers building white-label applications requiring multiple tenant-specific themes, teams experimenting with color palettes before committing to final designs, projects needing to match precise brand guidelines with exact color control, and anyone frustrated with manually converting hex colors to the HSL format required by shadcn/ui. The Theme Editor can be installed as a dev dependency via npm or integrated using the Scaflo CLI, bridging the gap between visual design and technical implementation to make theme customization accessible and efficient.
