Browser-Use

Browser-Use is an open-source framework that makes websites accessible to AI agents. Connect it to Lightcone’s cloud browsers for scalable, stealth-enabled web automation.

Install

pip install browser-use tzafon playwright
playwright install chromium

Example

from browser_use import Agent
from langchain_openai import ChatOpenAI
from tzafon import Lightcone
from playwright.async_api import async_playwright

async def main():
    # Create a Lightcone browser session
    client = Lightcone()
    session = client.computers.create(kind="browser")
    cdp_url = session.endpoints.get("cdp")

    # Connect Playwright to the Lightcone browser
    pw = await async_playwright().start()
    browser = await pw.chromium.connect_over_cdp(cdp_url)

    # Create a Browser-Use agent on the remote browser
    agent = Agent(
        task="Search for 'machine learning' on Wikipedia and summarize the first paragraph",
        llm=ChatOpenAI(model="gpt-4o"),
        browser=browser,
    )

    result = await agent.run()
    print(result)

    await browser.close()
    await pw.stop()
    client.computers.delete(session.id)

import asyncio
asyncio.run(main())

Why use Lightcone with Browser-Use?

By default, Browser-Use runs a local Chromium browser. Connecting it to Lightcone gives you:

• Cloud execution — No local browser needed; scale to many concurrent agents
• Stealth mode — Lightcone’s anti-detection features help agents access sites that block automation
• Residential proxies — Rotate IPs to avoid rate limiting
• Session persistence — Save and restore login state across agent runs

How it works

Browser-Use uses Playwright internally. Lightcone exposes a Chrome DevTools Protocol (CDP) endpoint for each browser session. You connect Playwright to Lightcone’s CDP URL instead of launching a local browser, and Browser-Use operates on the remote session transparently.
