Crew comms in one box

Crewbox

Crew comms for temporary events.

Chat, push-to-talk voice, patch sheets and lighting plots, running from one box on your own Wi-Fi with no internet on site. Crew scan a QR code, pick a name and they're in: no accounts, no app store.

macOS and Linux. Downloads the box, clears the macOS quarantine flag, and starts it.

In action

Chat Three crew phones in #stage: a message typed on one arrives on the other two a moment later.

Chat Crew join from the QR code on a phone: pick a name, enter the PIN, and land straight in the chat.

Patch sheets A festival patch sheet filled in cell by cell, then the sub-boxes, colour-coded, where they sit on stage.

Lighting A 28-fixture rig imported from MVR, drawn in 3D and coloured live by the sACN the desk is sending.

Lighting Moving a fixture onto its neighbour's DMX addresses flags a clash, and Address run repacks the truss to clear it.

Network audit A second console starts sending on universe 1. The audit flags two sources on one universe, then clears when the backup stops.

**Network audit** The report the network audit downloads for venue IT, grading each network and listing recent events.

Offline throughout A phone loses the box and keeps working: its message waits in the outbox, then delivers when the connection returns.

What it does

Chat

Channels, DMs, mentions, files and who's online. Messages queue in an outbox and survive dead phones, roaming and reboots.

Push-to-talk voice

The voice server is inside the box, so there is nothing else to install.

Patch sheets

Input patch per artist, sub-boxes, lineup, and CSV in and out.

Lighting

Fixture patch with DMX clash detection, positions, a plot, and MVR and GDTF import.

Network audit

The networks the box can see, graded for A/V use, with a report for venue IT.

Offline throughout

The box needs no internet and neither do the crew. When it has a connection it checks for updates daily, and an admin installs one in two presses.

Getting started

Run the box
On any machine on the venue network; a laptop is fine. It mints an admin password at setup, so write it down.
Share the QR
The box prints a join URL, a fresh event PIN and a QR code. Crew scan it and pick a name.
Check it
Admin → This box shows what is actually working on your machine and what to do about anything that isn't.

Worth knowing

Browsers need HTTPS for the mic

Browsers won't grant a microphone over plain http://, and the same rule blocks add to home screen. Voice works today in the Android app, which is exempt, and the iOS app will be too once it is on the App Store; for browsers the box needs HTTPS on a name you control.

iOS can't alert offline

Lock-screen alerts on iOS need Apple's push servers, which a site with no internet can't reach. The Android app holds its own connection to the box and buzzes while locked, so give Android phones to the roles that must not miss a call.
