What's the difference between Mantine and Radix UI?
Styled vs unstyled by default
Mantine ships with default visual styling you can theme and customize; Radix UI provides no visual styling at all, giving you behavior and accessibility handling while leaving every visual decision to you.
Scope of what's included
Mantine offers a broad set of over 100 components plus hooks covering many common UI needs like forms and date pickers; Radix UI focuses narrowly on a set of interactive primitives like dialogs and dropdowns, requiring you to build or source other components separately.
Speed vs flexibility trade-off
Mantine's included styling means faster initial development since components look reasonable immediately; Radix UI requires more upfront styling work but offers more flexibility for building a fully custom design system.
Radix's ecosystem context is shifting
Radix UI's own creators have built Base UI, a newer unstyled primitives library, which shadcn/ui adopted as its default in July 2026; Radix UI itself remains actively maintained and usable directly or through tools that still support it, including existing shadcn/ui projects.

Should you choose Mantine or Radix UI?
Choose Mantine if
- You want components that look good immediately without building your own styles
- You want a broad set of components and hooks covering many common needs
- You want built-in theming to customize Mantine's default look
- You want free prebuilt page templates via Mantine UI
Choose Radix UI if
- You want full control over every visual aspect of your components
- You're building a custom design system from scratch and just need accessible behavior
- You want a narrow, focused set of interaction primitives rather than a broad component library
- You're comfortable pairing primitives with your own styling solution (like Tailwind)
Switching between Mantine and Radix UI
Moving from Mantine to Radix UI means replacing Mantine's styled, ready-made components with Radix's unstyled primitives and writing your own visual styling for each one, trading faster initial development for more design flexibility. Moving from Radix UI to Mantine means replacing custom-styled primitives with Mantine's pre-styled components and adapting to Mantine's theming system instead of your own custom styles.
Mantine vs Radix UI: common questions
Does Radix UI include any visual styling at all?
No, Radix UI primitives are completely unstyled by design, handling only behavior, keyboard navigation and accessibility attributes. All visual styling is left to the developer, often combined with a separate tool like Tailwind CSS.
Is Mantine fully customizable despite coming pre-styled?
Yes, Mantine's components come with default visual styling but are themeable, letting you adjust colors, spacing and other design tokens to match your own design system.
Are both libraries built for React?
Yes, both Mantine and Radix UI are built specifically for React.
What is Base UI and does it affect Radix UI?
Base UI is a newer unstyled primitives library built by the same team behind Radix UI, which shadcn/ui adopted as its default in July 2026. Radix UI itself remains actively maintained and is not deprecated.
Which is faster to get a working UI with?
Mantine is generally faster initially since its components come styled and ready to use; Radix UI requires writing your own styles for every primitive before you have a visually complete UI.
