Stagehand

Overview

Stagehand makes browser automation as easy as describing what you want in plain English. Built on Playwright by Browserbase, it adds AI-powered element detection and natural language action execution.

How It Works

1. Initialize — Create a Stagehand instance with your LLM
2. Navigate — Open any web page
3. Act — Describe actions in natural language
4. Extract — Pull structured data from the page

Use Cases

• Web automation — Automate repetitive web tasks
• E2E testing — Write tests that adapt to UI changes
• Data extraction — Scrape dynamic web apps reliably
• Workflow automation — Multi-step web processes

Getting Started

import { Stagehand } from "@browserbase/stagehand";
const stagehand = new Stagehand({ modelName: "gpt-4o" });
await stagehand.init();
await stagehand.page.goto("https://github.com/login");
await stagehand.act({ action: "enter username and click sign in" });

Example

const products = await stagehand.extract({
  instruction: "extract product names and prices",
  schema: z.object({ name: z.string(), price: z.string() }).array()
});
