Stagehand

Stagehand is the AI browser automation framework: an open-source SDK for developers and LLMs to reliably control web browsers using natural language and code.

Stagehand delivers reliable web automation for production-grade AI agents and developer workflows. Built as a powerful, open-source alternative to Playwright, it fuses the predictability of code with the adaptability of AI. The framework provides four core primitives: **Act** (execute actions via natural language), **Extract** (pull structured data using schemas), **Observe** (discover available on-page actions), and **Agent** (automate entire workflows autonomously). It is compatible with all Chromium-based browsers (Chrome, Edge) and is designed for maintainable, flexible automation, solving common reliability issues in web scraping and testing.
