ButtonHub

Coming soon

The show’s controls, on the crew’s own phones.

ButtonHub is a macOS app that runs on the show Mac, next to Companion and QLab. The crew open a link on their own phones and get the handful of controls they are responsible for, without ever being handed the whole show file, and without being shown Companion or QLab at all.

Built for theatre, live events and broadcast, where a failure is not a bad user experience but a mistake in front of an audience.

What it does

Buttons, on any phone

Fire Companion buttons and QLab cues from a phone on the venue network. Every person gets their own link, PIN locked, carrying only their own controls.

The MD screenFor the pit

A live cue readout built for the musical director. The standing cue, what is coming next, and the whole list underneath, marked and moving as the playhead does. Large enough to read from behind a keyboard, and it follows QLab in about a third of a second.

TalkbackChat

A chat between the people running the show, on phones and on the operators’ screens. Fixed phrases for the calls that repeat, and colour-coded full-screen flashes for the ones nobody can afford to miss. One link, as many named voices as the show needs.

Main and backup

Two machines watching each other, with one URL that follows whichever is driving. Handing the show over is a person’s decision, never an automatic guess, because a network drop and a dead machine look identical from the outside.

On the venue network, or off it

Works on the local network with nothing else involved. Where there is no shared network, it travels over our own relay instead, and a printed QR sheet gets each person to their own page.

How it works

  1. ButtonHub runs on the show Mac

    A normal macOS application sitting alongside Companion and QLab, on the machine that is already running the show.

  2. It drives Companion and QLab for you

    Companion over its HTTP API, QLab over OSC. Companion itself is never exposed to the phones.

  3. The crew open a link

    Anything with a browser on the venue network. No app to install, no accounts, and each link is PIN locked and carries only its own buttons.

  4. Off the venue network, it still works

    Where there is no shared network, the same links travel over our own relay instead, and a printed QR sheet gets each person to their own page.

Pick the shape of the rig

The mode decides what the machine does and what follows what. These are the five, drawn the same way they appear in the app.

Solo

One Mac. The phones talk to it, nothing paired and nothing mirrored. The right mode for most gigs.

Two Macs, paired. Playheads, presses and settings follow the main. The backup fires nothing at all until somebody promotes it.
