In plain English

Stagehand is a framework for automating web browsers using a mix of plain English instructions and code. It solves the problem that existing browser automation tools force you to choose between writing precise but brittle low-level code or using AI agents that are flexible but unpredictable. Stagehand lets you use whichever approach fits each situation. When you know exactly what you want, click this button, fill in this form, you write it as code. When you are navigating an unfamiliar page or need the automation to adapt, you describe what you want in natural language and the AI figures out how to do it. The two approaches can be mixed freely in the same script. A key feature is self-healing automation: Stagehand caches the steps it has figured out, so repeated runs happen without calling the AI at all. If the website changes and the automation breaks, it automatically recognizes this and uses the AI again to adapt. This makes it practical for production use, not just one-off scripts. You would use Stagehand to build automated web workflows, scraping data, filling out forms, testing web apps, or building AI agents that need to browse the web. The library is written in TypeScript and works with a browser connection. A Python version is also available in a separate repository.

Copy-paste prompts

Prompt 1
Show me how to use Stagehand to scrape product names and prices from an e-commerce site, mixing code for known elements with AI instructions for dynamic content.
Prompt 2
How do I set up Stagehand to fill out a multi-step form where some fields change based on user input, using self-healing to handle layout changes?
Prompt 3
Write a Stagehand script that logs into a website and navigates to a specific page, using plain English for unfamiliar UI and code for precise clicks.
Prompt 4
How does Stagehand's caching work to avoid repeated AI calls, and how do I trigger re-learning when a website changes?
