Browser Use - Kernel

Browser Use is an agent framework, not a browser host — so there’s nothing to port. You keep your agent code and change where its browser comes from. If you’re running Browser Use against its own cloud, or against a local Chromium, this is the change.

Point the agent at a Kernel browser

from browser_use import Agent, BrowserSession
from kernel import Kernel

kernel = Kernel()
kernel_browser = kernel.browsers.create(stealth=True, timeout_seconds=600)

session = BrowserSession(cdp_url=kernel_browser.cdp_ws_url)

agent = Agent(
    task="Find the top story on Hacker News and summarize it",
    browser_session=session,
)

try:
    await agent.run()
finally:
    kernel.browsers.delete_by_id(kernel_browser.session_id)

The full setup, including the model configuration and running it on the App Platform, is on the Browser Use integration page.

What you gain

Things to check

Keep the default context and page. Kernel browsers launch with one already open. Browser Use handles this, but custom harness code should use contexts()[0] / pages()[0] rather than creating new ones.
Set timeout_seconds. An agent that stalls shouldn’t leave a browser running — see termination.
Concurrency is per plan. Running many agents at once is bounded by concurrency and limits.
