Apps SDK UI

Apps SDK UI is a lightweight, accessible design system for building high-quality ChatGPT apps with the Apps SDK. It provides Tailwind-integrated design tokens, a curated React component library, and utilities optimized for consistent experiences inside ChatGPT.

Features

Design tokens for colors, typography, spacing, sizing, shadows, surfaces, and more.
Tailwind 4 integration pre-configured with Apps SDK UI's design tokens.
Accessible components, built on Radix primitives with consistent styling.
Utilities for dark mode, responsive layouts, and ChatGPT-optimized behaviors.
Minimal boilerplate — import styles, wrap with a provider, start building.

Prerequisites

Apps SDK UI requires React 18 or 19 and Tailwind 4.

React: https://react.dev/learn/installation
Tailwind 4: https://tailwindcss.com/docs/installation

Installation

1. Install the package

npm install @openai/apps-sdk-ui

2. Setup styles

Add the foundation styles and Tailwind layers to the top of your global stylesheet (e.g. main.css):

@import "tailwindcss";
@import "@openai/apps-sdk-ui/css";
/* Required for Tailwind to find class references in Apps SDK UI components. */
@source "../node_modules/@openai/apps-sdk-ui";

/* The rest of your application CSS */

Then import your stylesheet before rendering any components:

// Must be imported first to ensure Tailwind layers and style foundations are defined before any potential component styles
import "./main.css"

import { StrictMode } from "react"
import { createRoot } from "react-dom/client"
import { App } from "./App"

createRoot(document.getElementById("root")!).render(
  
    
  ,
)

3. Configure router (optional)

helps define your default router link component, used in components like and ``.

This provider is optional - router links can also be passed directly to components via the as prop.

// Must be imported first to ensure Tailwind layers and style foundations are defined before component styles
import "./main.css"

import { AppsSDKUIProvider } from "@openai/apps-sdk-ui/components/AppsSDKUIProvider"
import { StrictMode } from "react"
import { createRoot } from "react-dom/client"
import { Link } from "react-router"
import { App } from "./App"

declare global {
  interface AppsSDKUIConfig {
    LinkComponent: typeof Link
  }
}

createRoot(document.getElementById("root")!).render(
  
    
      
    
  ,
)

Start building

Your project is now ready to use Apps SDK UI!

Here's an example of a simple reservation card, using Tailwind classes and components.

import { Badge } from "@openai/apps-sdk-ui/components/Badge"
import { Button } from "@openai/apps-sdk-ui/components/Button"
import { Calendar, Invoice, Maps, Members, Phone } from "@openai/apps-sdk-ui/components/Icon"

export function ReservationCard() {
  return (
