Custom proxies allow you to use your own proxy servers with Kernel browsers. This is useful when you have existing proxy infrastructure or specific proxy requirements not covered by Kernel’s managed options.

​
Configuration

HTTP and HTTPS proxies are supported for custom proxy configurations. If no protocol is specified, HTTPS is used by default.
Specify the host, port, and optional authentication credentials for your proxy server: 
import { Kernel } from '@onkernel/sdk';
const kernel = new Kernel();

const proxy = await kernel.proxies.create({
  type: 'custom',
  name: 'my-private-proxy',
  protocol: 'https',
  config: {
    host: 'proxy.example.com',
    port: 443,
    username: 'user123',
    password: 'secure_password'
  }
});

const browser = await kernel.browsers.create({
  proxy_id: proxy.id
});

​
Configuration Parameters

  • host (required) - Proxy server hostname or IP address
  • port (required) - Proxy server port (1-65535)
  • username - Username for proxy authentication
  • password - Password for proxy authentication (minimum 5 characters)
When creating a proxy with authentication, provide the password. The API response will only indicate if a password exists (has_password: true) but won’t return the actual password for security reasons.
