[Outdated] Using Selenium Remote (Selenium Grid) with browser_use

Note: This article is old.
This method can no longer be used with browser-use 0.2 and later. If you are using browser-use versions after that, you need to perform remote debugging via Chrome’s debugging port.
browser_use uses Playwright internally.
Since Playwright can use Selenium Remote (Selenium Grid), you can use a remote browser simply by setting the environment variable SELENIUM_REMOTE_URL to the Selenium Remote URL (a URL like http://selenium-grid.example.com:4444).
However, by default it runs in headless mode, and you can’t specify a context, so it’s not customizable.
If you create a customized Playwright instance and inject it into the Agent, you can use Playwright exactly the way you want.
Sample code
from langchain_openai import ChatOpenAI
from browser_use import Agent, Browser
from playwright.async_api import async_playwright
import asyncio
import os
os.environ['SELENIUM_REMOTE_URL'] = 'http://selenium-grid.example.com:4444'
prompt = f'''
* Please open https://www.example.com.
* The login button...
* In Email ...
'''
sync def main():
async with async_playwright() as p:
# Create and customize a Playwright browser
playwright_browser = await p.chromium.launch(
headless=False, # Disable headless mode
)
browser_context = await playwright_browser.new_context(
viewport={'width': 670, 'height': 377}, # Set viewport size
locale='ja-JP', # Language setting
ignore_https_errors=True, # Ignore certificate errors
)
# Create a browser_use Browser and inject the Playwright browser
browser = Browser()
browser.playwright_browser = playwright_browser
browser.playwright = p
# Inject the browser_use Browser into the Agent
agent = Agent(
task=prompt,
llm=ChatOpenAI(model="gpt-4.1-mini"),
browser=browser,
browser_context=browser_context,
)
result = await agent.run(max_steps=5)
print(result)
if __name__ == "__main__":
asyncio.run(main())
