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**. ## Choose your OS Choose between installing the Linux package or running zrok with Docker (Linux, macOS, or Windows). On Linux, zrok frontdoor is implemented natively as a system service provided by the `zrok-share` DEB or RPM package. On macOS and Windows, zrok frontdoor is implemented as a Docker Compose project which reserves a public subdomain for your website or service and manages a zrok environment that's separate from the Docker host.
