mantinedev/mantine
A fully featured React components library
Mantine is a React component library with 100+ components, 80+ hooks, and a full ecosystem of add-ons (forms, charts, notifications, rich text editor, etc.). It targets React/TypeScript developers who want a batteries-included UI kit with first-class dark mode and CSS-variable-based theming without reaching for MUI or Chakra.
- Theming system is built on CSS custom properties, so overriding colors/spacing/radius works at the CSS level without JS runtime cost — you can even do per-component overrides via `classNames` and `styles` props consistently across every component.
- The hooks package (@mantine/hooks) is genuinely useful standalone: useIntersection, useVirtualized, useHotkeys, useIdle, etc. — not just wrappers around browser APIs but things you'd otherwise write yourself.
- The ecosystem packages (Spotlight, Modals manager, Notifications) follow the same API conventions as core, so integrating them doesn't feel like dropping in a third-party lib. They share the theme and className override system.
- Active maintenance and frequent releases — last push is current (June 2026), changelog is detailed, and the help.mantine.dev FAQ site shows the team actually responds to common integration pain points rather than just closing issues.
- No headless/unstyled variant. If your design system diverges significantly from Mantine's defaults, you're fighting the existing styles rather than building on a behavior-only primitive. Radix UI or Headless UI serve that use case better.
- Server Components support is limited — MantineProvider and many interactive components require 'use client', which means Next.js App Router projects end up with larger client bundles than necessary and can't render Mantine components on the server without workarounds documented in their own FAQ.
- The form library (@mantine/form) is basic compared to React Hook Form or Zod-integrated solutions — no built-in async validation, no field array performance optimizations, and schema library integration is manual.
- Bundle size can creep up fast. @mantine/core is not tree-shakeable at the sub-component level in all bundler setups, and pulling in charts + tiptap + carousel adds recharts + prosemirror + embla as peer deps, which aren't light.
