January 2026 - Base UI Documentation

Full documentation for Base UI components.

We've shipped full documentation for Base UI components.

When we launched npx shadcn create in December, we introduced the ability to choose between Radix and Base UI as your component library. Today, we're following up with complete documentation for all Base UI components.

What's New

• Full Base UI docs - Every component now has dedicated documentation for Base UI, covering usage, props, and examples.
• Rebuilt examples - All component examples have been rebuilt for both Radix and Base UI. Switch between them to see the implementation differences.
• Side-by-side comparison - The docs make it easy to compare how components work across both libraries.

Same Abstraction, Different Primitives

The goal remains the same: give you a consistent API regardless of which primitive library you choose. The components look and behave the same way. Only the underlying implementation changes.

// Works the same whether you're using Radix or Base UI.
import { Dialog, DialogContent, DialogTrigger } from "@/components/ui/dialog"

If you're starting a new project, run npx shadcn create and pick your preferred library. The CLI handles the rest.
