Stagehand
Open-source AI browser automation SDK from Browserbase — write resilient browser agents using natural language with act, extract, observe, and agent primitives.
Overview
Stagehand: AI Browser Automation SDK
Stagehand is the open-source browser automation SDK from Browserbase — the framework that lets you write resilient browser agents using natural language instructions instead of brittle CSS selectors. Where Playwright and Selenium break every time a website's DOM changes, Stagehand uses AI to resolve high-level intents like "click the submit button" at runtime.
The four primitives — act, extract, observe, agent — give developers a complete vocabulary for building browser automations that survive page redesigns and adapt to new sites without rewrites.
Key Features
- Four primitives: act, extract, observe, agent — natural-language browser control
- AI resolution at runtime — selectors auto-recover when sites change
- TypeScript and Python SDKs; works locally with any Chromium browser
- Optional integration with Browserbase cloud browsers for production scale
- Element + action caching in v3 reduces LLM calls and runtime cost
Ideal Use Case
Building AI agents that browse the web reliably — research agents, e-commerce checkout flows, web scrapers that need to work across many sites, and any automation that traditionally required brittle CSS selectors.
Why Use Stagehand
The browser automation space has been frozen for a decade. Stagehand changes the maintenance economics: scripts written in natural language self-heal across site updates, which means automation projects that used to require ongoing engineering investment can now run with much lower upkeep.
FAQ
Q: Do I need Browserbase to use Stagehand? A: No. Stagehand works locally with any Chromium browser. Browserbase is optional for production cloud-browser deployment.
Q: How does Stagehand compare to Playwright? A: Stagehand wraps Playwright underneath but adds AI primitives. You get Playwright's speed plus selector resilience.
Q: Does Stagehand support Python? A: Yes. There's a Python SDK alongside the TypeScript primary.
tl;dr
Open-source AI browser automation SDK. Natural-language primitives, self-healing selectors, Playwright underneath. From Browserbase.
