Connect your existing Chrome browser to preserve authentication.

​
Basic Example

import asyncio
from browser_use import Agent, Browser, ChatOpenAI

# Connect to your existing Chrome browser
browser = Browser(
    executable_path='/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',
    user_data_dir='~/Library/Application Support/Google/Chrome',
    profile_directory='Default',
)

agent = Agent(
    task='Visit https://duckduckgo.com and search for "browser-use founders"',
    browser=browser,
    llm=ChatOpenAI(model='gpt-4.1-mini'),
)
async def main():
	await agent.run()

if __name__ == "__main__":
    asyncio.run(main())
Note: You need to fully close chrome before running this example. Also, Google blocks this approach currently so we use DuckDuckGo instead.

​
How it Works

  1. executable_path - Path to your Chrome installation
  2. user_data_dir - Your Chrome profile folder (keeps cookies, extensions, bookmarks)
  3. profile_directory - Specific profile name (Default, Profile 1, etc.)
