React Grab allows you to select an element and copy its context (like HTML, React component, and file source)
It makes tools like Cursor, Claude Code, Copilot run up to 66% faster

Run this command to install React Grab into your project. Ensure you are running at project root (e.g. where the next.config.ts or vite.config.ts file is located).
npx @react-grab/cli@latestIf you're using a React framework or build tool, view instructions below:
Add this inside of your app/layout.tsx:
import Script from "next/script";
export default function RootLayout({ children }) {
return (
<html>
<head>
{/* put this in the <head> */}
{process.env.NODE_ENV === "development" && (
<Script
src="//unpkg.com/react-grab/dist/index.global.js"
crossOrigin="anonymous"
strategy="beforeInteractive"
/>
)}
</head>
<body>{children}</body>
</html>
);
}Add this into your pages/_document.tsx:
import { Html, Head, Main, NextScript } from "next/document";
export default function Document() {
return (
<Html lang="en">
<Head>
{/* put this in the <Head> */}
{process.env.NODE_ENV === "development" && (
<Script
src="//unpkg.com/react-grab/dist/index.global.js"
crossOrigin="anonymous"
strategy="beforeInteractive"
/>
)}
</Head>
<body>
<Main />
<NextScript />
</body>
</Html>
);
}Your index.html could look like this:
<!doctype html>
<html lang="en">
<head>
<script type="module">
// first npm i react-grab
// then in head:
if (import.meta.env.DEV) {
import("react-grab");
}
</script>
</head>
<body>
<div id="root"></div>
<script type="module" src="/src/main.tsx"></script>
</body>
</html>First, install React Grab:
npm install react-grabThen add this at the top of your main entry file (e.g., src/index.tsx or src/main.tsx):
if (process.env.NODE_ENV === "development") {
import("react-grab");
}React Grab can send selected element context directly to your coding agent. This enables a workflow where you select a UI element and an agent automatically makes changes to your codebase.
This means no copying and pasting - just select the element and let the agent do the rest. Learn more →
