Choose Your Primitive Library

Both Radix UI and Base UI provide accessible, unstyled primitives. Choose the one that fits your project best.

Radix UI

The established choice

Battle-tested in production
Extensive component library
Large community ecosystem

style: "radix-vega"

Base UI

The lightweight alternative

Active development
Modern API
New and advanced components

style: "base-vega"

Radix UI

Base UI

Key difference: radix-ui vs @base-ui/react/tooltip

Same styling, different primitives

Simple Configuration

One setting in your components.json controls both the UI library and visual style.

components.json

{
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "base-maia",
  "rsc": true,
  "tsx": true,
  "tailwind": {
    "config": "",
    "css": "app/globals.css",
    "baseColor": "neutral",
    "cssVariables": true
  },
  "aliases": {
    "components": "@/components",
    "utils": "@/lib/utils",
    "ui": "@/components/ui"
  }
}

Style

{library}-{style}

Examples

radix-vega, radix-nova, radix-maia
