**zrok frontdoor** is the heavy-duty front door to your app or site. It makes your website or app available to your online audience through the shield of zrok.io's hardened, managed frontends.

  ## Overview

zrok frontends are the parts of zrok that proxy incoming public web traffic to zrok backend shares via OpenZiti. When you use zrok with a `zrok.io` frontend, you're using **zrok frontdoor**. `zrok.io` is zrok-as-a-service by NetFoundry, the team behind OpenZiti. You need a free account to use **zrok frontdoor**.

On Linux, zrok frontdoor is implemented natively as a system service provided by the `zrok-share` DEB or RPM package.

If you'd prefer to run zrok in Docker instead of installing the package then you can follow the Docker instructions. With Docker, the steps are the same for Linux, [macOS](./?os=Mac+OS), and [Windows](./?os=Windows).
