About This Template

Shadcn UI Customizer is an open-source web application built with Next.js, TypeScript, Tailwind CSS, and shadcn/ui, providing an intuitive visual interface with interactive color pickers for customizing shadcn/ui themes without manual CSS variable editing. This powerful tool enables developers and designers to customize comprehensive design tokens including background and foreground colors, primary, secondary, and accent colors, card, popover, and input styles, border properties, and border radius settings, all through a user-friendly web interface that provides real-time previews of changes. Inspired by the original shadcn/ui theme customizer, this enhanced version offers additional customization options and improved developer experience for teams establishing brand-specific design systems. Perfect for agencies customizing shadcn/ui for multiple clients, product teams aligning UI themes with brand guidelines, designers collaborating with developers on design system specifications, or any project where theme customization without diving into CSS files accelerates the design-to-development workflow. With deployment on Vercel and a TypeScript-heavy codebase (99%), the customizer demonstrates how visual tools can enhance the shadcn/ui ecosystem, making theme customization accessible to team members who may not be comfortable editing raw CSS variables while maintaining the flexibility and control that developers expect.
