Rocket Show and QLab: an alternative without a Mac

QLab is the standard for cue-based playback in theatre, and it needs a Mac. Rocket Show is a dedicated box run from any browser. Here is an honest look at which one fits your show.

If you are looking for a QLab alternative, you probably have one of three reasons: you do not have a Mac, you do not want a computer on stage, or you need something that runs on its own every day. Rocket Show answers all three, and it does fewer things than QLab. This page sets out the differences, so you can decide before you spend anything.

In short: QLab is software for the Mac with very deep cue programming, large audio routing and multi-screen video. Rocket Show is a small device (SPARK, or free on a Raspberry Pi) that plays audio, video, DMX lighting and MIDI on one timeline per cue, is run from any phone, tablet or laptop, and can run unattended. If your show needs QLab's depth, keep QLab. If it needs to run reliably without a Mac, read on.

Where QLab is the better choice

Where Rocket Show is the better choice

The cue grid of Rocket Show on a tablet
The cue grid: one button per cue, for shows not played in a fixed order.

Moving a show from QLab

There is no import, but the building blocks map onto each other:

Cue list
A set: the cues in running order. Shows played out of order use the cue grid, one button per cue.
Audio and video cues
The files of a composition. Cues that start together become one composition; a delay in milliseconds starts a file later.
Auto-continue
A cue marked in the set to start the next one when it ends.
Light cues
Scenes in the lighting designer, drawn on the composition's timeline, or lighting actions that set channels at a moment.
MIDI and network cues
MIDI and HTTP actions at a position in a composition.
Hotkeys and triggers
MIDI controls, digital inputs and HTTP requests that start, stop or select cues.

Copy the audio and video files over, build one composition per cue, and test-play each one in the editor. The documentation covers every screen.

Questions

Is there a Windows or Linux version of QLab?
No. QLab 5 runs on macOS 11 (Big Sur) or later only. Figure 53, its maker, says a port would mean rewriting it from scratch. QLab Remote on an iPad or iPhone controls a Mac running QLab, but does not replace it.
Can I control Rocket Show from Windows?
Yes. Rocket Show runs on its own device, and you build and run the show from a browser: Windows, macOS, Linux, an iPad or an Android phone all work. Nothing is installed on them.
Can Rocket Show replace QLab in a theatre?
For shows whose cues are sound, video, DMX lighting and MIDI started in order or from a cue grid, often yes. For productions built on cue stacks with fades, many outputs, microphones, multi-projector video or MSC and OSC, QLab is the better tool.
Is Rocket Show free?
The Community Edition is free and open source, on your own Raspberry Pi 5: the same show engine, editor and lighting designer as SPARK. Rocket Show SPARK, the ready-made device, is bought once, with no licence fees and no subscription; it adds over-the-air updates, backup and restore, a factory reset and HTTPS.
