About
About Shadcn UI Customizer
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.

Frequently asked questions
Everything you need to know before you ship with Shadcn UI Customizer.
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. It is an open source template in the shadcn.io collection of 215.
Shadcn UI Customizer is made by Railly, an independent developer; shadcn.io lists it but did not make it. Railly has 2 templates in the collection, and the author's page lists them.
The listing tags Shadcn UI Customizer with Next.js, React, Tailwind and UI Kits & Component Libraries. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The Shadcn UI Customizer page embeds its live demo from shadcn-ui-customizer.vercel.app, and links to it so you can open the real deployment before you clone.
The Shadcn UI Customizer listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.
Clone the repository (git clone https://github.com/Railly/shadcn-ui-customizer), then follow the README. The Shadcn UI Customizer page shows the usual steps and a terminal block with the commands to copy.
Install dependencies with npm install or pnpm install, then run npm run dev. The README in the Shadcn UI Customizer repository says which package manager and environment variables it needs.
No. Shadcn UI Customizer is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.
Shadcn UI Customizer is tagged Next.js, so it deploys wherever a Next.js app does, such as Vercel, a Node.js server or a container. Its README may add steps for its own services.
The Shadcn UI Customizer listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/Railly/shadcn-ui-customizer), and ask the author if there isn't one.
That depends on Shadcn UI Customizer's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.
Attribution follows Shadcn UI Customizer's license. Many permissive licenses ask you to keep the copyright notice and license text in your copy; its LICENSE file says exactly what.
No. The Pro license covers shadcn.io's own Pro code, blocks and premium templates. Shadcn UI Customizer is the author's project, under the terms in its repository.
Railly supports Shadcn UI Customizer, through its GitHub repository: read the docs, open an issue or look for discussions. shadcn.io does not maintain it.
Yes. Once you clone it, Shadcn UI Customizer is your own code: change the theme, add pages and connect your backend. It uses shadcn/ui, so you can also add more components the same way.
Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that Shadcn UI Customizer uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.
Yes, with Pro. The shadcn.io MCP server's search_templates tool finds templates by what they are, and returns each one's repository and live demo, so your editor can set up Shadcn UI Customizer for you. Your files stay on your machine.
The collection has 19 other open source UI Kits & Component Libraries templates like Shadcn UI Customizer, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/ui-kits-and-component-libraries.
Railly has 1 other template in the collection, including Tinte. The author's page lists them all.
Yes. The 14 premium templates (Solaris, Reframe Labs, Spherule and Max and more) are built by shadcn.io and come with every Pro plan, if you want maintained code with a design file.
