# Kernel

> Run Magnitude agents on Kernel cloud browsers

[Kernel](https://www.onkernel.com/docs/introduction) 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

```bash theme={null}
npm install @onkernel/sdk
```

### 2. Initialize Kernel and create a browser

Import the libraries and create a cloud browser session:

```typescript theme={null}
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:

```typescript theme={null}
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:

```typescript theme={null}
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:

```bash theme={null}
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](https://www.onkernel.com/docs/quickstart) to deploy and run your Magnitude automation on Kernel's infrastructure.
