+  ## 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**.
