**Last updated:** June 30, 2026 · **Reviewed by:** DesignRevision team · 8 shadcn component libraries compared

ReUI has quickly become one of the largest registries in the [shadcn/ui](/alternatives/shadcn) ecosystem. Built by KeenThemes, it offers 1,000+ copy-paste components and animated effects across 68 categories — all composed from shadcn primitives — and it uniquely ships both Base UI and Radix UI versions of every component. For teams that want far more than the core shadcn/ui set, it is a huge head start.

But it is not the only shadcn registry, and the ecosystem is full of strong options. Origin UI and Kibo UI offer large component collections, Magic UI and Aceternity UI focus on animation, and shadcn Studio bundles theming with components. Depending on whether you want breadth, motion, or a specific style, another option may fit better.

This guide explains what ReUI is, whether it is free, how it relates to shadcn/ui, and then ranks the **8 best ReUI alternatives** — the leading shadcn component libraries and registries — so you can pick the right one for your project.

## Key Takeaways

## What Is ReUI?

<a href="https://reui.io" rel="nofollow noopener" target="_blank">ReUI</a> is a free, open-source component library and shadcn registry for the shadcn/ui ecosystem, built by KeenThemes. It describes itself as a "design-forward shadcn kit," and it offers 1,000+ production-ready components across 68 categories, all composed from shadcn/ui primitives.

What sets it apart is breadth and flexibility. The registry covers far more than the core shadcn/ui set, and it uniquely ships **both Base UI and Radix UI versions** of its components — so you can use whichever primitive layer your project is built on, something most registries do not offer. It is built with React, TypeScript, Tailwind CSS and Motion, and includes animated effects alongside standard components. The source lives at <a href="https://github.com/keenthemes/reui" rel="nofollow noopener" target="_blank">github.com/keenthemes/reui</a>.

Because it is a first-class shadcn registry, components install through the shadcn CLI and land in your own codebase, so you own and customize them. KeenThemes also offers a paid ReUI Pro tier with templates and premium blocks.

**Key stats:**
- Free, open-source shadcn/ui component library and registry
- 1,000+ components across 68 categories, built on shadcn primitives
- Ships both Base UI and Radix UI versions of components
- Built with React, TypeScript, Tailwind CSS and Motion (with animations)
- Installs through the shadcn CLI; you own the copied code
- Open source (MIT); paid ReUI Pro tier
- By KeenThemes; repository: github.com/keenthemes/reui

## Is ReUI Free?

Yes. The ReUI component library is **free and open source** under the MIT license — all 1,000+ components are free to use, including in commercial projects, and you copy them into your own codebase.

KeenThemes also sells **ReUI Pro**, a paid tier with premium templates and blocks. So it follows a freemium model: the core registry is free, and the premium assets are the paid upgrade. If you only need the open-source components, there is no paywall.

## ReUI vs shadcn/ui

A common question is how ReUI relates to **shadcn/ui** — and the answer is that they are layers, not competitors. shadcn/ui gives you the core, accessible copy-paste components; ReUI is a much larger registry built on those same primitives.

| | ReUI | shadcn/ui |
|---|---|---|
| **What it is** | Large component registry | Core component collection |
| **Catalog** | 1,000+ components | Core set |
| **Primitives** | Base UI and Radix UI | Radix UI (adding Base UI) |
| **Animations** | Built in (Motion) | Minimal |
| **Install** | shadcn CLI (registry) | shadcn CLI |
| **License** | MIT (free; paid Pro) | MIT (free) |

In short: you typically use shadcn/ui for the foundation and pull in ReUI when you want a much larger set of components and animated effects on top — they are designed to work together, not replace one another.

## Why Look for ReUI Alternatives?

ReUI is excellent, but it is not the right fit for every project. Here are the most common reasons developers evaluate alternatives.

### 1. You want a specific animation style

ReUI includes animated effects, but its style may not match your brand. Libraries like Magic UI, Aceternity UI and Cult UI each take a different approach to motion.

### 2. You want a smaller, simpler set

A 1,000-component registry can be more than you need. If you want a focused, curated collection, a smaller library or the core shadcn/ui set is easier to navigate.

### 3. You want theming bundled in

If you want a theme editor alongside your components, shadcn Studio combines theming with a large component and block library in one place.

### 4. You want advanced application components

For complex app components — Gantt charts, Kanban boards, editors — a registry like Kibo UI focuses on the application layer rather than general UI and animations.

## The 8 Best ReUI Alternatives in 2026

Every option below is a shadcn/ui component library or registry, so it fits the same copy-paste, Tailwind-based workflow as ReUI.

> **Our pick to ship fast: Shards UI** — If you want accessible shadcn/ui components you can preview and copy without browsing a 1,000-component registry, start with the free [Shards UI gallery](/components) — curated components and blocks, with [Shards Pro](/components) adding premium blocks and templates. It is the fastest way to assemble a polished UI on the shadcn foundation.

### 1. shadcn/ui

**Best for: the accessible foundation underneath**

<a href="https://ui.shadcn.com" rel="nofollow noopener" target="_blank">shadcn/ui</a> is the copy-paste component collection that ReUI and most registries build on. Use it for your core, accessible components, then add a registry when you need more. See our [shadcn alternatives guide](/alternatives/shadcn) for the wider ecosystem.

**License:** MIT (free, open source)
**Tech stack:** React, Radix UI, Tailwind CSS
**Strengths:** The standard foundation, huge community, code ownership
**Weaknesses:** Core components only — no large registry or animations

### 2. Origin UI

**Best for: a large free component collection**

<a href="https://originui.com" rel="nofollow noopener" target="_blank">Origin UI</a> is a big collection of free, copy-paste components built on shadcn/ui and Tailwind. Like ReUI, it focuses on breadth — hundreds of variations of inputs, buttons, dialogs and more — without a paid tier for the core set.

**License:** Free, open source
**Tech stack:** React, Tailwind CSS
**Strengths:** Very large free catalog, lots of variants
**Weaknesses:** Less animation focus than ReUI

### 3. Kibo UI

**Best for: advanced application components**

<a href="https://www.kibo-ui.com" rel="nofollow noopener" target="_blank">Kibo UI</a> is a shadcn/ui registry of advanced, composable components — Gantt charts, Kanban boards, editors and more. It complements general libraries by covering the application layer. See our [Kibo UI alternatives guide](/alternatives/kibo-ui) for how it compares.

**License:** MIT (free, open source)
**Tech stack:** React, shadcn/ui, Tailwind CSS
**Strengths:** Advanced app components, shadcn-native, free
**Weaknesses:** Narrower than a general registry like ReUI

### 4. Magic UI

**Best for: animated marketing components**

<a href="https://magicui.design" rel="nofollow noopener" target="_blank">Magic UI</a> is a library of 150+ animated components and effects designed to pair with shadcn/ui. It is the go-to for marketing pages that need motion. See our [Magic UI alternatives guide](/alternatives/magic-ui) for the animated-component landscape.

**License:** Free, open source (paid Pro templates)
**Tech stack:** React, Tailwind CSS, Motion
**Strengths:** Polished animations, great for landing pages
**Weaknesses:** Marketing-focused; narrower than a full registry

### 5. Aceternity UI

**Best for: bold, flashy hero effects**

<a href="https://ui.aceternity.com" rel="nofollow noopener" target="_blank">Aceternity UI</a> offers striking, animation-forward components — 3D cards, spotlights, animated backgrounds — that make a landing page memorable. It leans further into visual "wow-factor" than ReUI.

**License:** Free components (paid templates)
**Tech stack:** React, Tailwind CSS, Motion
**Strengths:** Eye-catching effects, great for hero sections
**Weaknesses:** Effects can be heavy; less suited to repeatable system components

### 6. Cult UI

**Best for: modern, animated shadcn components**

<a href="https://www.cult-ui.com" rel="nofollow noopener" target="_blank">Cult UI</a> is a set of polished, animated components built on shadcn/ui and Motion. It offers interactive components with a refined, modern feel — a smaller, more curated take than ReUI.

**License:** Free, open source
**Tech stack:** React, TypeScript, Tailwind CSS, Motion
**Strengths:** Tasteful animations, modern aesthetics, shadcn-native
**Weaknesses:** Smaller catalog

### 7. shadcn Studio

**Best for: components plus a theme editor**

<a href="https://shadcnstudio.com" rel="nofollow noopener" target="_blank">shadcn Studio</a> combines a large library of components and blocks with a visual theme editor. If you want to customize a theme and grab ready-made UI in the same place, it is a strong all-in-one option.

**License:** Freemium
**Tech stack:** React, shadcn/ui, Tailwind CSS
**Strengths:** Components, blocks and theming together
**Weaknesses:** Broader scope than a focused registry

### 8. HextaUI

**Best for: modern, clean shadcn components**

<a href="https://www.hextaui.com" rel="nofollow noopener" target="_blank">HextaUI</a> is a modern collection of copy-paste components built on React and Tailwind in the shadcn style, with clean designs and a growing catalog.

**License:** Free, open source
**Tech stack:** React, Tailwind CSS
**Strengths:** Clean modern designs, easy copy-paste
**Weaknesses:** Smaller and newer than ReUI

## Quick Comparison Table

| Library | Focus | Catalog size | Animations | License |
|---------|-------|--------------|------------|---------|
| **ReUI** | shadcn registry | 1,000+ | Yes | MIT (freemium) |
| **shadcn/ui** | Core components | Core set | Minimal | MIT |

| **Cult UI** | Animated components | Small | Moderate | Free |
| **shadcn Studio** | Components + theming | Large | Some | Freemium |
| **HextaUI** | Modern components | Growing | Some | Free |

## How to Choose a ReUI Alternative

Pick based on what you want:

- **Need the accessible foundation first?** Start with [shadcn/ui](/alternatives/shadcn) and add a registry on top.
- **Want broad, free component coverage?** Origin UI for breadth, or [Kibo UI](/alternatives/kibo-ui) for advanced app components.
- **Want animations?** [Magic UI](/alternatives/magic-ui), Aceternity UI or Cult UI.
- **Want theming bundled in?** shadcn Studio.
- **Just want components to ship today?** Copy from our free [Shards UI gallery](/components).

All of these pair with Tailwind and shadcn/ui, so you can mix several in one project. The right choice comes down to how much breadth you need, whether you want animations, and whether you want extras like theming bundled in. Explore our [developer tools](/tools) for more building blocks along the way.
