# Quickstart

> Run browser automation in the cloud

Sandboxes are the **easiest way to run Browser-Use in production**. We handle agents, browsers, persistence, auth, cookies, and LLMs. It is also the **fastest way to deploy** - the agent runs right next to the browser, so latency is minimal.

## Basic Example

Wrap your function with `@sandbox()`:

```python theme={null}
from browser_use import Browser, sandbox, ChatBrowserUse
from browser_use.agent.service import Agent

@sandbox()
async def my_task(browser: Browser):
    agent = Agent(task="Find the top HN post", browser=browser, llm=ChatBrowserUse())
    await agent.run()

await my_task()
```

## With Cloud Parameters

```python theme={null}
@sandbox(
    cloud_profile_id='your-profile-id',      # Use saved cookies/auth
    cloud_proxy_country_code='us',           # Bypass captchas, cloudflare, geo-restrictions
    cloud_timeout=60,                        # Max session time (minutes)
)
async def task(browser: Browser, url: str):
    agent = Agent(task=f"Visit {url}", browser=browser, llm=ChatBrowserUse())
    await agent.run()

await task(url="https://example.com")
```

**What each does:**

* `cloud_profile_id` - Use saved cookies/authentication from your cloud profile
* `cloud_proxy_country_code` - Route through country-specific proxy for stealth (bypass captchas, Cloudflare, geo-blocks)
* `cloud_timeout` - Maximum time browser stays open in minutes
