About OpenRGB

OpenRGB replaces the separate lighting apps that each hardware maker ships with one program. It talks directly to motherboards, RAM, graphics cards, keyboards, mice, fans and LED strips from brands such as ASUS, Corsair, Gigabyte, MSI, Razer and Logitech, so you can set colours and effects across mixed hardware without installing Armoury Crate, iCUE or Synapse. The interface is deliberately plain and light on memory and CPU. A network SDK lets other programs drive your lights, which is how game integrations, music visualisers and ambient lighting are built, and a plugin system adds an effects engine and a visual layout editor. OpenRGB is free and open source under the GPL v2 and runs on Windows, Linux and macOS, including ARM boards like the Raspberry Pi. Device support depends on reverse-engineering, so new hardware can lag behind, and fancy effects need plugins.

Best for: PC builders with mixed-brand RGB gear who want one light, open-source app on any OS.
