# Headless Mode

Kernel browsers ship in `headful` mode by default. In headful mode, the launched browser has a corresponding GUI. This enables features like [live view](/browsers/live-view) and [replays](/browsers/replays).

`headless` mode runs without a visual interface. They generally run faster and have a lighter footprint (1 GB rather than headful's 8 GB), resulting in significant cost savings. This is useful for short-lived or highly concurrent browser automations.
Some bot detectors may detect headless mode.

To launch a Kernel browser in `headless` mode, set its config:

<CodeGroup>
  ```typescript Typescript/Javascript theme={null}
  import Kernel from '@onkernel/sdk';

  const kernel = new Kernel();

  const kernelBrowser = await kernel.browsers.create({
    headless: true,
  });
  ```

  ```python Python theme={null}
  from kernel import Kernel

  kernel = Kernel()

  kernel_browser = kernel.browsers.create(headless=True)
  ```
</CodeGroup>

<Info>
  [Live View](/browsers/live-view) and [Replays](/browsers/replays) are not available in headless mode.
