description: Open-source Python agent that lets LLMs navigate, fill forms, and extract from the web.
llm: true
---

The Browser Use integration connects Steel's browser infrastructure with the Browser Use agent framework, 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 Python -wc
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()
```

Full runnable starters:

*   Auto-solve captchas with Steel + Browser Use: [Captcha auto recipe →](/cookbook/browser-use-captcha-auto)
*   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.
