Mantine
Full-featured React component library and hooks collection. Mantine ships 100+ components (Button, Modal, DataTable, DatePicker, RichTextEditor, etc.) and 50+ hooks (useForm, useLocalStorage, useMediaQuery, etc.). Unlike Radix UI which is unstyled primitives, Mantine provides fully styled components with a complete design system, dark mode, theming API, and form utilities. Well-regarded for quality, documentation, and active maintenance.

🔒 Security
Local library — no network access. CSS modules scoping prevents style injection attacks. MIT licensed.
⚡ Reliability
Best When
You want a comprehensive, well-documented React component library with everything included — forms, hooks, data display, overlays — and don't need a fully custom design.
Avoid When
You have a highly custom design system, need unstyled primitives, or are not using React.
Use Cases
- • Build React admin dashboards and internal tools with 100+ ready-to-use styled components including DataTable, Charts, and DatePicker
- • Use Mantine hooks (useForm, useDisclosure, useInterval) as standalone utilities without the full component library
- • Implement dark mode in React applications using Mantine's built-in color scheme management without custom CSS
- • Build rich text editor features using Mantine's TipTap-based rich text editor component for user-generated content
- • Create responsive layouts and modals using Mantine's Grid, AppShell, and Modal components for dashboard-style applications
Not For
- • Highly custom design systems where every pixel must be controlled — Radix UI + custom styling gives more control
- • Very large codebases where Mantine's styling approach (CSS modules) may conflict with existing styling setup
- • Non-React frameworks — Mantine is React-only
Interface
Authentication
Local library — no authentication.

Known Gotchas
- ⚠ Mantine 7.x uses CSS modules instead of CSS-in-JS (Emotion) from 6.x — this is a major architecture change; Mantine 6 and 7 are not compatible and migration requires significant changes
- ⚠ Mantine PostCSS plugin (@mantine/postcss-preset) must be configured for styles to work — missing PostCSS config results in unstyled components
- ⚠ Dark mode uses ColorSchemeScript in the document head to prevent flash of unstyled content — missing this script causes visible color scheme flash on page load
- ⚠ Mantine form (useForm hook) has its own validation and state management separate from React Hook Form — using both in the same form creates state conflicts
- ⚠ Mantine components use CSS variables for theming — custom themes must use Mantine's createTheme API, not CSS overrides, for the theme to apply correctly
- ⚠ Mantine packages are modular (@mantine/core, @mantine/hooks, @mantine/dates, etc.) — install only the packages containing components you use to reduce bundle size
