About
About Mantine Theme Builder
This comprehensive toolkit evolved from an experimental project into a full-featured theme generation interface that simplifies the process of modernizing Mantine's styling by enabling developers to quickly generate and integrate contemporary design systems. The shadcn design inspiration brings the elegant aesthetics popularized by shadcn/ui to the Mantine ecosystem, bridging the gap between Mantine's comprehensive component library and modern design trends. Perfect for development teams using Mantine UI seeking modern aesthetics, designers creating custom themes for Mantine applications, agencies building multiple projects with consistent Mantine styling, or developers transitioning from other UI libraries who want Mantine components with familiar design patterns.
The theme export functionality generates ready-to-use configuration objects that can be copied and pasted directly into projects, eliminating manual theme construction and reducing the time from design decision to implementation. By providing a visual interface for theme customization, MantineHub makes sophisticated Mantine theming accessible to team members who may not be familiar with Mantine's theming API structure while maintaining the full power and flexibility that experienced developers expect.

Frequently asked questions
Everything you need to know before you ship with Mantine Theme Builder.
MantineHub (previously Mantine Theme Builder) is an open-source web tool built with TypeScript, Next.js, CSS, SCSS, and Tailwind CSS, designed to create modern, customizable shadcn-inspired themes for Mantine UI components by providing extensive color palette selection, border radius control, light/dark mode toggling, theme object export functionality, and support for all Mantine components with pre-built UI component "Blocks". It is an open source template in the shadcn.io collection of 215.
Mantine Theme Builder is made by Rubixcube innovations, an independent developer; shadcn.io lists it but did not make it. Rubixcube innovations has 1 template in the collection, and the author's page lists them.
The listing tags Mantine Theme Builder with Next.js, React, SCSS, Tailwind and Mantine. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The Mantine Theme Builder page embeds its live demo from mantinehub.com, and links to it so you can open the real deployment before you clone.
The Mantine Theme Builder 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/RubixCube-Innovations/mantine-theme-builder), then follow the README. The Mantine Theme Builder 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 Mantine Theme Builder repository says which package manager and environment variables it needs.
No. Mantine Theme Builder 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.
Mantine Theme Builder 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 Mantine Theme Builder listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/RubixCube-Innovations/mantine-theme-builder), and ask the author if there isn't one.
That depends on Mantine Theme Builder'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 Mantine Theme Builder'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. Mantine Theme Builder is the author's project, under the terms in its repository.
Rubixcube innovations supports Mantine Theme Builder, 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, Mantine Theme Builder 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 Mantine Theme Builder 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 Mantine Theme Builder for you. Your files stay on your machine.
The collection has 10 other open source SCSS templates like Mantine Theme Builder, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/scss.
Rubixcube innovations has no other templates in the collection.
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.
