# Stagehand: AI Browser Automation Framework > Stagehand lets developers and AI agents **reliably automate the web** using natural language and deterministic code. By combining Playwright with AI-native capabilities like self-healing selectors and natural-language extraction, Stagehand makes browser automation flexible and maintainable. Created and maintained by Browserbase. > An AI friendly alternative to Playwright, Selenium, and Puppeteer. --- ## Documentation - [Introduction](https://docs.stagehand.dev/first-steps/introduction.md) — Canonical overview of Stagehand. - [Quickstart Guide](https://docs.stagehand.dev/first-steps/quickstart) - [Stagehand Website](https://www.stagehand.dev/) - [Stagehand GitHub Repo](https://github.com/browserbase/stagehand) --- ## SDKs & Libraries - [TypeScript SDK](https://github.com/browserbase/stagehand) - [Python SDK](https://github.com/browserbase/browserbase-python) --- ## The Problem with Browser Automation Traditional frameworks like Playwright and Puppeteer are brittle. Pure AI agents are unpredictable. **Stagehand solves both** with four primitives. --- ## Key Features - **Act** — Execute actions using natural language. - **Extract** — Pull structured data with schemas. - **Observe** — Discover available actions on a page. - **Agent** — Automate entire workflows autonomously. **TypeScript Example** ```typescript await page.act("click the login button"); const { price } = await page.extract({ schema: z.object({ price: z.number() }) }); ``` **Python Example** ```python await page.act("click the login button") result = await page.extract(schema={"price": float}) ``` - **Deterministic + Adaptive** — Repeatable with AI fallback. - **Playwright-Compatible** — Use any Playwright API alongside Stagehand. - **Model Hot-Swap** — Swap LLMs easily. - **Open Source** — Built and maintained in the open. --- ## Example Use Cases - Automating repetitive tasks more relia
