# Cloud browser + open source agent

> Run the open-source Browser Use agent on a cloud stealth browser. Your code, our infrastructure.

The [open-source library](/open-source/introduction) runs the agent on your machine. By default it also runs the *browser* on your machine, which means no stealth, no residential proxy, and no CAPTCHA solving. This page connects the two: keep your local agent code, point it at a cloud browser.

## Connect by CDP URL

Create a cloud browser, then pass its CDP URL to the library's `Browser`:

```python theme={null}
import asyncio
from browser_use import Agent, Browser, ChatOpenAI
from browser_use_sdk.v3 import AsyncBrowserUse

async def main():
    client = AsyncBrowserUse()
    cloud_browser = await client.browsers.create(proxy_country_code="us")

    try:
        agent = Agent(
            task="Find the current price of iPhone 16 on amazon.de",
            llm=ChatOpenAI(model="gpt-4o"),
            browser=Browser(cdp_url=cloud_browser.cdp_url),
        )
        await agent.run()
    finally:
        await client.browsers.stop(cloud_browser.id)

asyncio.run(main())
```

The agent behaves exactly as it does locally. The browser it drives is a [stealth Chromium](/cloud/browser/stealth) with [CAPTCHA solving](/cloud/browser/captcha) and a [residential proxy](/cloud/browser/proxies), and you can watch it work through the session's `live_url`.
