Stagehand

Open-source SDK for building browser agents that act, observe, extract data, and run workflows using natural-language instructions.

Stagehand

Stagehand helps developers automate real websites with browser actions such as clicking, filling forms, navigating, observing actionable elements, and extracting structured data. Its AI resolves instructions at runtime instead of relying only on fixed selectors.

It works locally with Chromium and can connect to Browserbase for cloud browsers, session replay, observability, captcha solving, and deployment. Stagehand itself is open source; Browserbase infrastructure, model usage, and related services may cost extra.

Features

  • act() performs browser actions from plain-English instructions
  • extract() returns structured page data with Zod schema validation
  • observe() identifies actionable elements before an action
  • agent() runs multi-step browser workflows autonomously
  • Works locally with Chromium without requiring Browserbase
  • Connects to Browserbase cloud browsers for production deployment
  • Open source under the MIT license
  • Supports TypeScript, Python, and Go SDKs

Use cases

  • Automate multi-step workflows across changing websites
  • Extract structured information from pages without a site API
  • Test web applications with actions that adapt to DOM changes
  • Navigate login-protected portals and fill forms
  • Deploy browser agents on Browserbase cloud infrastructure
