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

Basic Example

Just wrap your function with @sandbox(): 
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

@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
