Quick Start

Get started with SmoothUI in just one command:

# Using SmoothUI CLI (recommended)
npx smoothui-cli add siri-orb

# Or using shadcn CLI
npx shadcn@latest add @smoothui/siri-orb

Then use the component:

import { SiriOrb } from "@/components/smoothui/ui/SiriOrb";

export default function App() {
  return <SiriOrb size="200px" />;
}

Installation

Using SmoothUI CLI

The SmoothUI CLI provides an interactive way to browse and install components with automatic dependency resolution.

# Add a single component
npx smoothui-cli add siri-orb

# Add multiple components
npx smoothui-cli add siri-orb rich-popover animated-input

# Interactive mode - browse and select components
npx smoothui-cli add

# List all available components
npx smoothui-cli list

Features:

Interactive component picker with search and categories
Auto-detects package manager (npm, pnpm, yarn, bun)
Auto-detects component paths and tsconfig aliases
Shows dependency tree before installation
Handles file conflicts with overwrite prompts
Auto-installs npm dependencies

Using shadcn CLI

SmoothUI is an official shadcn registry, so you can install components directly using the @smoothui namespace:

# Install a single component
npx shadcn@latest add @smoothui/siri-orb

# Install multiple components
npx shadcn@latest add @smoothui/rich-popover @smoothui/animated-input

Manual Installation

If you prefer to install components manually, you can copy the component files directly:

Install dependencies:

pnpm add motion tailwindcss lucide-react clsx tailwind-merge

Copy component files from the components directory
Set up utilities:

# Create lib/utils/cn.ts
mkdir -p lib/utils

// lib/utils/cn.ts
import { clsx, type ClassValue } from "clsx";
import { twMerge } from "tailwind-merge";

export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs));
}

Usage

Basic Usage

import { SiriOrb } from "@/components/smoothui/ui/SiriOrb";

export default function App() {
  return (
    <div className="flex min-h-screen items-center justify-center">
      <SiriOrb
        size="200px"
        colors={{
          bg: "oklch(95% 0.02 264.695)",

🤖 AI Assistant Integration

With MCP support, AI assistants like Claude, Cursor, and GitHub Copilot can:

Discover Components: Browse all available SmoothUI components
Install Components: Automatically install components with dependencies
Provide Usage Examples: Get code examples and integration help
Smart Suggestions: Receive intelligent component recommendations

Quick MCP Setup

Configure your registry in components.json:

{
  "registries": {
    "@smoothui": "https://smoothui.dev/r/{name}.json"
  }
}

Install MCP server:

npx shadcn@latest mcp init --client claude
