# Run Browser Use in the Cloud on Steel
URL: https://docs.steel.dev/integrations/browser-use

The Browser Use integration connects Steel's browser infrastructure with the [Browser Use agent framework](/cookbook/topics/browser-use), enabling AI models to perform complex web interactions. Agents can navigate websites, fill forms, click buttons, extract data, and complete multi-step tasks – all while leveraging Steel's reliable cloud browsers for execution. This integration bridges the gap between AI capabilities and real-world web applications without requiring custom API development.

### Requirements

*   **Steel API Key**: Active Steel subscription
*   **Python**: 3.11+
*   **Supported models**: vision-capable models like GPT-5, Claude Sonnet 4, or Gemini 3 Pro

### Connect Steel to Browser Use

Pass Steel's CDP URL into a Browser Use `BrowserSession`:

```python
from browser_use import Agent, BrowserSession
from browser_use.llm import ChatOpenAI
from steel import Steel

client = Steel(steel_api_key=STEEL_API_KEY)
session = client.sessions.create()
cdp_url = f"{session.websocket_url}&apiKey={STEEL_API_KEY}"

agent = Agent(
    task="Find the latest news on Steel.dev",
    llm=ChatOpenAI(model="gpt-5", api_key=OPENAI_API_KEY),
    browser_session=BrowserSession(cdp_url=cdp_url),
)
result = await agent.run()
```

*   Hand off captchas to a human via Steel Live View: [Manual captcha recipe →](/cookbook/browser-use-captcha-manual)

### FAQ

### Do I need to change my existing Browser Use code to use Steel?

No — pass a `BrowserSession(cdp_url=...)` into your `Agent` and Browser Use drives Steel's cloud browser instead of a local one. Your task, LLM config, and `agent.run()` loop stay the same.

### How do I connect Browser Use to a Steel browser session?

Create a session with `client.sessions.create()`, build the CDP URL as `f"{session.websocket_url}&apiKey={STEEL_API_KEY}"`, and pass it to `BrowserSession(cdp_url=cdp_url)` on the `Agent`.

### Does Browser Use work with Steel's proxies, stealth mode, and CAPTCHA solving?

Yes — these are session-creation options (e.g. `use_proxy`, `solve_captcha`, `stealth_config` on `sessions.create`), invisible to Browser Use itself. The page links dedicated recipes for auto-solving CAPTCHAs and handing them to a human.

### Which LLMs work with Browser Use on Steel?

Vision-capable models — the page calls out GPT-5, Claude Sonnet 4, and Gemini 3 Pro, and the example wires `ChatOpenAI(model="gpt-5")`. You also need Python 3.11+. For up-to-date model recommendations for browser agents, check the [Steel leaderboard](https://leaderboard.steel.dev/).

### Can a human take over when the agent hits a CAPTCHA?

Yes — Steel's Live View lets a person solve the CAPTCHA in the running session while the agent waits. The page links a manual-captcha recipe showing this hand-off pattern.
