Vibe code Stagehand withDirector

Most existing browser automation tools either require you to write low-level code in a framework like Selenium, Playwright, or Puppeteer, or use high-level agents that can be unpredictable in production. By letting developers choose what to write in code vs. natural language, Stagehand is the natural choice for browser automations in production.

1. Choose when to write code vs. natural language: use AI when you want to navigate unfamiliar pages, and use code (Playwright) when you know exactly what you want to do.

2. Preview and cache actions: Stagehand lets you preview AI actions before running them, and also helps you easily cache repeatable actions to save time and tokens.

3. Computer use models with one line of code: Stagehand lets you integrate SOTA computer use models from OpenAI and Anthropic into the browser with one line of code.

Here's how to build a sample browser automation with Stagehand:

// Use Playwright functions on the page objectconstpage=stagehand.page;awaitpage.goto("https://github.com/browserbase");// Use act() to execute individual actionsawaitpage.act("click on the stagehand repo");// Use Computer Use agents for larger actionsconstagent=stagehand.agent({provider:"openai",model:"computer-use-preview",});awaitagent.execute("Get to the latest PR");// Use extract() to read data from the pageconst{ author, title}=awaitpage.extract({instruction:"extract the author and title of the PR",schema:z.object({author:z.string().describe("The username of the PR author"),title:z.string().describe("The title of the PR"),}),});

Start with Stagehand with one line of code, or check out ourQuickstart Guide for more information:

Stagehand is best when you have an API key for an LLM provider and Browserbase credentials. To add these to your project, run:

cp .env.example .envnano .env# Edit the .env file to add API keys

This project heavily relies onPlaywright as a resilient backbone to automate the web. It also would not be possible without the awesome techniques and discoveries made bytarsier,gemini-zod, andfuji-web.
