Quickstart

You can use npx to create a new project. You should have npx included with npm, the default package manager for Node.js.

npx create-browser-app

To use our Contexts with Stagehand, run:

npx create-browser-app --example persist-context

You can easily deploy Stagehand scripts to Vercel in one line! Simply run:

npx create-browser-app --example deploy-vercel
npx vercel deploy

We also have an example using CUA agents, where we put OpenAI Operator against Anthropic’s Claude Computer Use in a heated game of chess. It’s just ten lines of Stagehand code, try it with:

npx create-browser-app --example chess

You can also use the version of Stagehand that’s on main but not released yet. This will have the bleeding edge features, but they may not be fully prod-ready yet. To test this version, try:

npx create-browser-app --alpha

It will ask you the following questions:

✔ What is the name of your project? my-app
✔ Would you like to start with a quickstart example? Yes
✔ Select AI model: Anthropic Claude 3.7 Sonnet
✔ Run locally or on Browserbase? Local
✔ Run browser in headless mode (hide Chromium popup)?  No

cd my-app
npm install
npm run start

Use the package manager of your choice to install the dependencies. We also have a postinstall script that will automatically install the Playwright browser with playwright install.
