otf-kit vs react-native-ui-lib — picking an RN UI library in 2026

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

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

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

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

// 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.

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.
