- **Compared with:** react-native-ui-lib (RNUI) (https://wix.github.io/react-native-ui-lib)
- **Verdict:** Pick RNUI Lib if you want the broadest possible RN-only component coverage from a battle-tested library. Pick otf-kit if you need cross-platform parity (web + native), 17 swappable themes, or a full-stack kit.
- **Best for:** React Native developers, Cross-platform startups, Teams comparing established RN UI libraries

## TL;DR

react-native-ui-lib (RNUI for short, sometimes "Wix RNUI") is one of the longest-running and broadest RN component libraries — 100+ components, used heavily inside Wix and across the RN ecosystem. It's RN-only, has its own design language, and ships theming primitives.

otf-kit makes a different bet: cross-platform from day one (web parity via Radix), 17 picker-driven themes, and pairs with paid full-stack kits. The component count favors RNUI on native; otf-kit closes the gap on web parity and product shape.

## Feature matrix

| | otf-kit | RNUI Lib |
|---|---|---|
| **Platforms** | Web + iOS + Android | iOS + Android only |
| **Component count** | 80+ native (198+ web) | 100+ native |
| **Engine** | Tamagui (compile-time) | StyleSheet-based, custom theming |
| **Web rendering** | Radix-based web parity | None — RN-only |
| **Themes** | 17 picker-driven themes | Theme manager + colors |
| **Full-stack kits** | SaaS Dashboard ($99) · Fitness ($99) | None |
| **Animation** | Motion + GSAP integrations | Reanimated-based built-ins |
| **Pricing** | SDK free · Kits $99 each | Free, MIT |

## When RNUI Lib wins

- You're **RN-only** with no web parity plan and want the broadest possible component coverage.
- You need **niche surfaces** (Wheel Picker, Slider with custom thumbs, Carousel with parallax, etc.) that exist in RNUI but not in most alternatives.
- You're already using **Wix's stack** or familiar with RNUI's API.
- You want **Reanimated-driven animations** built into components.

## When otf-kit wins

- You're shipping **cross-platform**. RNUI is RN-only; otf-kit ships Radix-based web components with parity API.
- You want **17 designed themes** swappable at runtime.
- You want a **full-stack kit** with auth + Stripe + Drizzle wired — not just components.
- You prefer **Tamagui's compile-time optimization** over RNUI's runtime StyleSheet approach.

## Code comparison — Button

```tsx
// RNUI Lib
import { Button } from 'react-native-ui-lib'

<Button label="Click me" backgroundColor="#1a1a1a" onPress={onClick} />
```

```tsx
// otf-kit
import { Button } from '@otfdashkit/ui-native'

<Button variant="default" onPress={onClick}>Click me</Button>
```

## Migrating from RNUI to otf-kit

The mental shift is mainly in styling — RNUI's `<View bg-blue50>` modifier-prop pattern is unique. otf-kit uses Tamagui's prop API on native (`bg="$blue50"` works) plus the `style` prop.

| RNUI | otf-kit |
|---|---|
| `<Button label="...">` | `<Button>label</Button>` |
| `<TextField>` | `<Input>` + `<Label>` |
| `<Card>` | `<Card>` |
| `<Dialog>` | `<Dialog>` |
| `<Toast>` | `<Toast>` |
| `<Picker>` | `<Select>` |
| `<DateTimePicker>` | Compose `<Popover>` + headless date picker |
| `<Carousel>` | Use `react-native-reanimated-carousel` |

The hardest migrations are RNUI's niche components (Wheel Picker, Hint, Image with custom overlays). For those, you can keep RNUI as a peer dependency and use both libraries side-by-side.

## FAQ

**Is RNUI Lib actively maintained?**
Yes — Wix maintains it as a public-facing artifact of their internal RN system. Releases are regular.

**Does otf-kit have a Wheel Picker / Carousel?**
Not in the SDK directly. The SaaS Dashboard kit includes a basic carousel; for a wheel picker you'll need a community package. RNUI is more feature-complete on these niche surfaces.

**Can I mix RNUI and otf-kit?**
Yes — they don't share theme systems but coexist fine. Use otf-kit for the 80% of common UI and reach for RNUI for niche components.
