Ambar UI

Ambar UI is a modern component library for Svelte 5.
Copy individual components into your project — or install the whole package via npm.
Every component is a single .svelte file, built with Svelte 5 runes and Tailwind CSS v4.
No wrapper libraries. No hidden magic. You own the code.

npm install @ambar-ui/svelte

Or copy any .svelte file directly from src/lib/components/.

Real-time chart — Feed any live data source (WebSocket, polling, game loop) via a single latestPrice prop. Smooth 60fps animation built in. → docs

Full-featured Sidebar — 4 item styles, 3 variants, collapsible icon rail, offcanvas mobile drawer, nested items, badges, animations. → docs

Live theme engine — 6 themes × 12 accent colors × 9 fonts. Everything is a CSS variable, persisted per-user. Toggle live on the docs site. → theming

AI-ready — Machine-readable component reference at /llms.txt. Paste into Claude, Cursor, or Copilot for accurate code generation.

Zero config — just CSS variables:

@import 'tailwindcss';

@theme inline {
  --color-accent: oklch(0.6 0.2 265);
}
