CyberDeck on iPhone in landscape, showing a Companion surface with live button state.

What it is

CyberDeck registers with Bitfocus Companion as a surface. Companion assigns it pages, sends button bitmaps, and receives presses and encoder turns. Configured by Companion, not by you.

The phone or iPad reflects the live state of whichever Companion surface you've assigned to it. Page navigation, button bitmaps, encoders, lock screens — all of it. When Companion changes the surface, the device updates.

Everything runs over your local network. No cloud, no relay, no account. If your control computer and your phone are on the same Wi-Fi, you're ready.

How it works

Signal path CyberDeck connects from the control computer running Companion, over your LAN, to your iPhone or iPad. Control computer Companion 4.2+ LAN same Wi-Fi or VLAN iPhone / iPad CyberDeck v2
  • Companion configures it. Pages, bitmaps, encoder behavior — all on the Companion side.
  • Live both directions. Companion pushes button state to the device; the device sends presses and encoder turns straight back.
  • No cloud in the middle. Works offline as long as both ends are on the same network.
