Open source and free shadcn templates using Mantine

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". 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.
