- Pay as you go based on Browserbase sessions consumed
- Act, extract, observe: 3 simple primitives for web agents
- For TypeScript/JavaScript developers building browser agents
What is Stagehand?
Stagehand is an open source SDK from Browserbase that simplifies building browser agents in TypeScript. Instead of learning all of Playwright, Stagehand exposes three simple primitives: act (perform an action), extract (pull data), observe (see what is on the page). The LLM interprets natural language instructions and executes the right actions.
Strengths
Simple API vs Raw Playwright
Stagehand abstracts Playwright complexity. await page.act("Click the login button") is far more readable than the equivalent XPath.
LLM-Powered Interpretation
The LLM understands imprecise instructions and adapts actions. More robust than strict CSS selectors that break at the first UI change.
Open Source with Browserbase Backend
The code is open source. Browserbase provides the underlying cloud Chrome infrastructure.
Limits
Browserbase Dependency in Production
Locally, you can use a local browser. In production, Browserbase is the natural backend (paid).
TypeScript/JavaScript Only
No Python SDK. Python devs will prefer Browser Use.
Pricing
Pay as you go via Browserbase. Check stagehand.dev and browserbase.com for rates.
Alternatives
For Python browser automation: Browser Use. For no-code browser agents: Skyvern. For broader automation: Playwright with a custom LLM layer.
Verdict
Stagehand is the most ergonomic API for browser agents in TypeScript. If you're building a web agent in TypeScript, this is your starting point. For Python, Browser Use is the equivalent.
FAQ
Does Stagehand work with Claude or only GPT?
Stagehand supports multiple LLMs. OpenAI and Anthropic are the most commonly used.

Does Stagehand handle authentication and sessions?
Yes, session and cookie management is native, which is important for agents that log into services.
Is Stagehand documentation available in languages other than English?
