Kernel.sh

Integrate with Kernel browsers

AI agent instructions

Read the Notte skill and follow its setup instructions when setting up Notte or building browser automation. This is the shared source for CLI setup, authentication, and the browser-to-code workflow.

Kernel.sh is a developer platform that provides browser infrastructure for web automation. By integrating with Notte, you can use Kernel browser infra to run reliable browser automations using Chrome DevTools Protocol (CDP).

Adding Kernel to existing Notte implementations

1. Install Notte and Kernel SDK

Install the notte-sdk and kernel packages in your Python environment.

2. Create and connect a browser

Use Kernel’s cdp_ws_url as the cdp_url when starting a Notte session. Configure proxies, launch arguments, and viewport with Kernel before connecting.

Python

from kernel import Kernel
from notte_sdk import NotteClient

# Initialize clients
client = NotteClient()
kernel = Kernel()

# Create browser on Kernel
kernel_browser = kernel.browsers.create()

try:
    # Connect Notte to Kernel's browser
    with client.Session(cdp_url=kernel_browser.cdp_ws_url) as session:
        # Use Notte's features
        page = session.page
        page.goto("https://example.com")

        # Extract data with Notte's scraping
        result = session.scrape(instructions="Find the contact email")

        print(f"Result: {result}")

finally:
    # Clean up Kernel browser
    kernel.browsers.delete_by_id(kernel_browser.session_id)

The Notte context manager stops the Notte session. The finally block separately deletes the browser owned by Kernel, including when the automation fails.

Benefits of using Kernel with Notte

• No local browser management: Run automations without installing or maintaining browsers locally
• Scalability: Launch multiple browser sessions in parallel for concurrent tasks
• Cloud infrastructure: Leverage Kernel’s optimized browser infrastructure
• Session control: Programmatic control over browser lifecycle
