Kernel offers fast browser infrastructure for running browser automations at scale. By integrating with Kernel, you can run Magnitude agents and automations in production with cloud-hosted browsers.

​
Benefits of using Kernel with Magnitude

  • No local browser management: Run automations without installing or maintaining browsers locally
  • Scalability: Launch multiple browser sessions in parallel
  • Stealth mode: Built-in anti-detection features for web scraping
  • Session persistence: Maintain browser state across automation runs
  • Live view: Debug your cloud automations with real-time browser viewing

​
Adding Kernel to existing Magnitude implementations

Ready to go live? Run your existing Magnitude automation in production with Kernel’s cloud browsers by updating your browser configuration.

​
1. Install the Kernel SDK

npm install @onkernel/sdk

​
2. Initialize Kernel and create a browser

Import the libraries and create a cloud browser session: 
import { startBrowserAgent } from "magnitude-core";
import Kernel from '@onkernel/sdk';
import z from 'zod';

const client = new Kernel({
    apiKey: process.env.KERNEL_API_KEY,
});

const kernelBrowser = await client.browsers.create({
    viewport: {
        width: 1920,
        height: 1080
    }
});

console.log(`Live view url: ${kernelBrowser.browser_live_view_url}`);

​
3. Update your browser configuration

Replace your existing browser setup to use Kernel’s CDP URL and display settings: 
const agent = await startBrowserAgent({
    url: 'https://magnitasks.com',
    narrate: true,
    browser: {
        cdp: kernelBrowser.cdp_ws_url,
        contextOptions: {
            viewport: { width: 1920, height: 1080 }
        }
    },
    llm: {
        provider: 'anthropic',
        options: {
            model: 'claude-sonnet-4-20250514'
        }
    }
});

​
4. Use your agent

Use Magnitude’s agent methods with the Kernel-powered browser: 
await agent.act([
    'click on "Tasks" in the sidebar',
    'click on the first item in the "In Progress" column'
]);

const assignee = await agent.extract('Extract the task Assignee', z.string());

await agent.stop();

// Clean up the Kernel Browser Session
await client.browsers.deleteByID(kernelBrowser.session_id);

​
Quick setup with Kernel’s app template

Alternatively, you can use Kernel’s app template that includes a pre-configured Magnitude integration: 
npx @onkernel/create-kernel-app my-magnitude-app
Choose TypeScript as the programming language and then select Magnitude as the template. Then follow the Quickstart guide to deploy and run your Magnitude automation on Kernel’s infrastructure. For more information, see the Kernel documentation.
