WhiteCat was created and developed by Christoph Guillermet, a lighting and video designer working in contemporary theatre and dance.

With the open-source release in June 2013, Georges Khaznadar, Anton Langhoff and RuiSerge helped White Cat evolve significantly.

Development then stopped for many years. Nevertheless, White Cat kept running and retained a loyal user base.

In 2026, Jacques Bouault (arpschuino.fr) decided to resume development. The first task was to update the obsolete libraries and get the program compiling on a modern IDE.

White Cat is a software program dedicated to lighting for theatre, dance, and concerts. Since version 0.9.1 it runs on Windows, Linux (64-bit) and Raspberry Pi. Mac users can use it with BootCamp.

White Cat works with many DMX512 interfaces that you plug into your computer.

Dimmers can then be controlled by your PC.

The previous app developed by Christoph, Schwartzpeter, is still freely available under GPL license. It is no longer maintained.

White Cat is free and open source, under GPL license.

The White Cat design strives to be simple to use, and to give lighting technicians, lighting designers, video artists and artists in general, a comfortable, easy, and useful tool that works in many situations:

-Manual approach (Masters, Video tracking)

-Cue approach (Cue List and Automations)

-Multi-software approach (Midi messaging and remote control, DMX-In and Art-Net merging)
