Galaxy UI

67 components × 5 frameworks — copy-paste component library, shadcn-style

Beautiful, accessible components for Vue 3, React 18, Angular 20+, React Native, and Flutter — built on Radix primitives with Tailwind CSS v3/v4 support, from web to mobile.

Following the shadcn/ui philosophy: components are copied into your project and remain fully editable. No runtime lock-in.

Framework Parity

Framework	Components	Styling	Notes
React 18+	69	Radix UI + Tailwind CSS	Reference implementation
Vue 3	69	Radix Vue + Tailwind CSS	Full parity with React
Angular 20+	69	Radix NG + Tailwind CSS	Standalone components, ControlValueAccessor
React Native	67	NativeWind	Custom date pickers, NativeWind classes
Flutter	69	Material Design 3	Galaxy-prefixed widgets

Web-only (9 components): breadcrumb, command, combobox, dashboard-block, data-table, kbd, toolbar, resizable, scroll-area

Quick Start

bash

# Detect your framework and scaffold
npx @galaxy-stack/nebula-cli@latest init

# Add components
npx @galaxy-stack/nebula-cli@latest add button card dialog

# With theme preset
npx @galaxy-stack/nebula-cli@latest init --theme violet

AI-Native

Galaxy UI ships with an MCP server and an AI skill so AI assistants (Claude, Cursor, Windsurf) can build with Galaxy components using real APIs instead of hallucinated ones.

config.json

{
  "mcpServers": {
    "galaxy-ui": {
      "command": "npx",
      "args": ["-y", "@galaxy-stack/nebula-mcp"]
    }
  }
}

AI Skill

The galaxy-ui skill (in skills/) teaches AI assistants the correct CLI workflow, framework-specific gotchas, and component patterns. Install it into Claude/Codex skills directory or reference it in your prompts.
