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
Get started in 1 minute by adding this script tag to your app:
<script
src="//www.react-grab.com/script.js"
crossorigin="anonymous"
></script>If 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.
Install the Claude Code agent provider:
npm install @react-grab/claude-codeThe server runs on port 4567 and interfaces with the Claude Agent SDK.
Vite:
// vite.config.ts
import { startServer } from "@react-grab/claude-code/server";
if (process.env.NODE_ENV === "development") {
startServer();
}Next.js:
// next.config.ts
import { startServer } from "@react-grab/claude-code/server";
if (process.env.NODE_ENV === "development") {
startServer();
}import { attachAgent } from "@react-grab/claude-code/client";
attachAgent();Install the Cursor agent provider:
npm install @react-grab/cursorThe server runs on port 5567 and interfaces with the cursor-agent CLI.
Vite:
// vite.config.ts
import { startServer } from "@react-grab/cursor/server";
if (process.env.NODE_ENV === "development") {
startServer();
}Next.js:
// next.config.ts
import { startServer } from "@react-grab/cursor/server";
if (process.env.NODE_ENV === "development") {
startServer();
}import { attachAgent } from "@react-grab/cursor/client";
attachAgent();React Grab provides an public customization API. Check out the type definitions to see all available options for extending React Grab.
import { init } from "react-grab/core";
const api = init({
theme: {
enabled: true, // disable all UI by setting to false
hue: 180, // shift colors by 180 degrees (pink → cyan/turquoise)
crosshair: {
enabled: false, // disable crosshair
},
elementLabel: {
// when hovering over an element
backgroundColor: "#000000",
textColor: "#ffffff",
},
},
onElementSelect: (element) => {
console.log("Selected:", element);
},
onCopySuccess: (elements, content) => {
console.log("Copied to clipboard:", content);
},
onStateChange: (state) => {
console.log("Active:", state.isActive);
},
});
api.activate();
api.copyElement(document.querySelector(".my-element"));
console.log(api.getState());Want to try it out? Check the our demo.
