Chakra UI vs Ninna UI
Accessible React component library rebuilt on Ark UI (v3). Compare Chakra UI and Ninna UI side by side to find which React component library fits your project in 2026.
Quick Verdict
Chakra UI is one of the most ergonomic React libraries ever made — the style props API is a joy. But that ergonomics is powered by a JavaScript runtime and (historically) Emotion, which adds hydration cost and bundle weight. Ninna UI keeps a familiar prop-driven API but moves all theming to CSS, so you get a similar developer experience with zero theming runtime.
Feature Comparison
Side-by-side comparison of key features between Chakra UI and Ninna UI.
| Feature | Ninna UI | Chakra UI |
|---|---|---|
| Installation model | npm packages (12 scoped packages) | npm package (@chakra-ui/react) |
| Theming approach | CSS imports only - zero JS config | Panda CSS tokens + createSystem() (v3) |
| Dark mode | Automatic via CSS - no provider needed | ColorModeProvider (JS runtime) |
| Component count | 67 components | 100+ components (v3 Ark-based) |
| Accessibility | Radix UI internally for complex widgets | Built-in ARIA via Ark UI/Zag.js (v3) |
| Bundle size | Tree-shakeable, CSS-only theming | Medium (Panda CSS, no Emotion in v3) |
| Tailwind CSS | v4 native (CSS-first config) | Not native (Panda CSS styling system) |
| TypeScript | Strict mode, data-slot types | Good type support |
| Customization | 98 data-slot CSS targets + cn() | JS theme object (extendTheme) |
| Maintenance | Standard npm update | Standard npm update |
| SSR support | Full (React Router / Next.js) | Good (requires provider setup) |
| React version | React 19+ | React 18+ (v3 supports React 19) |
| Color system | oklch perceptual colors | Semantic tokens (Panda CSS) |
| Learning curve | Low - CSS imports + React props | Medium - Panda CSS, provider patterns |
| Update mechanism | npm update (semver) | npm update (semver) |
Why choose Ninna UI
Key advantages of Ninna UI over Chakra UI for your next project.
Zero runtime theming - CSS-only vs Chakra's Panda CSS token system
No Panda CSS build step - Ninna UI uses standard Tailwind CSS v4
Tailwind CSS v4 native - use utility classes alongside components
oklch perceptual colors vs Chakra's semantic token system
No provider wrappers needed (ChakraProvider, ColorModeProvider)
Honest trade-offs
Where Chakra UI has advantages - we believe in transparent comparisons.
100+ components - significantly more extensive than Ninna UI's 67
Mature ecosystem with large community (since 2019)
v3 supports React 19 alongside React 18
Built on Ark UI/Zag.js for robust state machines

Migrating from Chakra UI
Step-by-step guide to move your project from Chakra UI to Ninna UI.
- 1
Remove `ChakraProvider` and `ColorModeProvider` wrappers from your app root
- 2
Replace `@chakra-ui/react` imports with `@ninna-ui/*` packages
- 3
Replace `useColorMode()` with CSS class-based dark mode (`.dark` on root element)
- 4
Replace `createSystem()` / `extendTheme()` with CSS theme preset import - no JS config needed
- 5
Install Tailwind CSS v4 - Chakra v3 uses Panda CSS, Ninna UI uses Tailwind
- 6
Note: Theming becomes CSS-only, no Panda CSS build step needed
App setup
Chakra UI
import { ChakraProvider } from "@chakra-ui/react";
export default function App({ children }) {
return <ChakraProvider>{children}</ChakraProvider>;
}Ninna UI
// app.css
@import "tailwindcss";
@import "@ninna-ui/core/theme/presets/default.css";
// No provider needed — components just work.Removing the provider removes the JS theming runtime entirely.

Chakra UI vs Ninna UI: FAQ
What's the biggest difference between Chakra UI and Ninna UI?
Theming runtime. Chakra resolves themes in JavaScript through a provider; Ninna UI does theming entirely in CSS with no provider and no hydration cost. Both offer accessible, composable components with a clean API.
Does Ninna UI use Emotion or a CSS-in-JS runtime?
No. Ninna UI uses Tailwind CSS v4 and plain CSS custom properties. There is no Emotion, no styled-system runtime, and nothing to hydrate.
Is the developer experience similar?
Familiar but not identical. Ninna UI uses Tailwind classes and a focused set of props rather than Chakra's full style-prop system. Most Chakra users feel at home within a day.
