# Browser Use

> Run Browser Use agents on a Driver browser by passing the session's cdpUrl.

[Browser Use](https://browser-use.com) runs autonomous agents on a Chromium it controls. Pass it a Driver session's `cdpUrl` and it drives real Chrome on an ISP network instead.

```bash theme={"dark"}
pip install browser-use requests
```

```python Python theme={"dark"}
import asyncio, os, requests
from browser_use import Agent, Browser, ChatBrowserUse

API = "https://api.driver.dev"
headers = {"Authorization": f"Bearer {os.environ['DRIVER_API_KEY']}"}


async def main():
    r = requests.post(
        f"{API}/v1/browser/session", headers=headers, json={"country": "US", "duration": 900}
    )
    r.raise_for_status()
    session = r.json()
    try:
        browser = Browser(cdp_url=session["cdpUrl"])
        agent = Agent(
            task="Find the current price of Bitcoin", llm=ChatBrowserUse(), browser=browser
        )
        result = await agent.run()
        print(result)
    finally:
        requests.delete(
            f"{API}/v1/browser/session", headers=headers, params={"sessionId": session["sessionId"]}
        )


asyncio.run(main())
```

`ChatBrowserUse` takes a Browser Use Cloud model key (`BROWSER_USE_API_KEY`). Any LangChain-style chat model works in its place.

## Notes

* Agents take many steps. Set `duration` to cover the task (up to 3600 seconds) and stop the session in `finally`.
* Browser Use talks CDP directly, not through Playwright, so Patchright doesn't apply. The fingerprint problem is the same, and an agent framework issues more CDP commands than a plain script. Expect challenges on protected sites.
* Pin the `browser-use` version you tested with. The `Browser` and `Agent` constructors have changed between releases. Passing `cdp_url` is what stops it from launching or downloading its own browser.
* Watch the agent through the session's [live view](/docs/sessions/live-view). It's the fastest way to see where it goes wrong.
