(Often abbreviated as "QLC+")
Open-source lighting control for DMX, Artnet, s.ACN and more.
Designed for live shows, theatre, architectual installations, and venues.
QLC+ is powerful and user-friendly software to control lighting. QLC+ supports a huge amount of hardware, runs on Linux, Windows (10+), macOS (10.12+), and Raspberry Pi. Whether you're an experienced lighting professional or just getting started, QLC+ empowers you to take control of your lighting fixtures with ease. The primary goal of this project is to bring QLC+ to the level of available commercial software.

Compilation guides and platform-specific instructions are available in our GitHub Wiki.
If you're regularly updating QLC+ sources with git pull, you may encounter compiler warnings, errors, or unresolved symbols. We strive to keep the master branch free of critical errors; however, dependencies between objects can sometimes cause issues, requiring a full package recompilation rather than just updating recent changes.
We welcome contributions from the community to help make QLC+ even better. If you're working on something major, start a thread in the Development Forum first. Make sure you read the CONTRIBUTING.md document for more.
If you're reading this we already appreciate you. If you're just getting started with lighting you have absolutely no obligation to give us money. When QLC+ opens up revenue opportunities for you, we'd be very thankful for your support. GitHub sponsors is the prefered option.
If you're interested, QLC+ also has an official store where you can purchase clothing, themes, the Raspberry Pi image or one-on-one consultation with an expert.
