Radix UI Has a Free API You Should Know About

Radix UI is an open-source component library that gives you unstyled, accessible UI primitives for building high-quality React applications.

Why Radix UI Wins

A frontend engineer at a healthcare startup spent 3 weeks building an accessible dropdown menu from scratch. It still failed WCAG audits. With Radix UI, they had a fully accessible dropdown in 15 minutes.

Key Features:

• Fully Accessible — WAI-ARIA compliant out of the box
• Unstyled — Complete control over styling
• Composable — Build complex UIs from simple primitives
• SSR Ready — Full server-side rendering support

Quick Start

npm install @radix-ui/react-dialog @radix-ui/react-dropdown-menu

Dialog Example

import * as Dialog from "@radix-ui/react-dialog"

export function MyDialog() {
  return (
    <Dialog.Root>
      <Dialog.Trigger>Open Dialog</Dialog.Trigger>
      <Dialog.Portal>
        <Dialog.Overlay className="dialog-overlay" />
        <Dialog.Content className="dialog-content">
          <Dialog.Title>Edit Profile</Dialog.Title>
          <Dialog.Close>Save Changes</Dialog.Close>
        </Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  )
}

30+ Components

Dialog, Dropdown Menu, Popover, Tooltip, Tabs, Accordion, Slider, Switch, Checkbox, Radio Group, Select, Navigation Menu, Toast, and more.
