Stagehand

The SDK for browser agents with Playwright-style API, self-healing selectors, and support for TypeScript, Python, and Go.

Stagehand is an open-source SDK designed specifically for building browser agents, offering a developer-friendly alternative to Playwright that is optimized for AI-driven automation rather than testing. It provides familiar APIs including goto, click, locator, and screenshot, while adding self-healing selectors that automatically adapt when websites change. Stagehand runs as an extension inside the browser, making remote browser interactions as fast as local execution. With token-efficient hybrid accessibility tree trimming, agents receive only the page context they need. It supports TypeScript, Python, and Go, making it accessible across modern development stacks for teams building production-grade web automation.
