OpenRGB vs SignalRGB

OpenRGB controls RGB devices from multiple manufacturers through one application without relying on manufacturer software. It is free and open source under the GNU General Public License version 2, and runs on Windows, Linux, and macOS. The interface is designed to use little RAM and CPU. Device support is not uniform: listings distinguish fully supported, problematic, partial, unsupported, and not-applicable features. Its network-based SDK lets third-party software control supported devices and synchronize OpenRGB instances across multiple PCs; bindings are available for C++, Python, C#, and Java. Integrations include Artemis, Project Aurora, Home Assistant, and Keyboard Visualizer. Plugins can add synchronized effects, hardware-status indicators, third-party lighting integrations, and scheduled profile changes. The Effects Plugin includes options such as Rainbow, Breathing, audio visualizations, Ambilight, GIF playback, and GLSL shader rendering. The HTTP Hook plugin can trigger basic actions such as profile switching. Standalone Linux use may require udev rules for hardware access. Pipeline builds are unreleased development versions and may be unstable.

SignalRGB is a Windows app for controlling and synchronizing RGB lighting across devices. Its homepage says it supports more than 6,000 devices from brands including Razer, Corsair, SteelSeries, Logitech, and MSI. The free plan includes hundreds of customizable lighting effects, five built-in fan curves, and two macros. Pro adds a larger content library, advanced fan controls, customizable monitoring, and unlimited macros; its listed library includes 45+ game integrations, 250+ RGB effects, 20+ audio visualizers, and 20+ LCD screen themes. Named game integrations include Valorant, Apex Legends, Minecraft: Java Edition, Counter Strike 2, League of Legends, and Fortnite. Pro monitoring offers adjustable widgets, more sensor options, and a 24-hour lookback. Some people who have never had Pro may qualify for a free trial, with a valid payment method required. The privacy policy says SignalRGB collects device and technical details, including specifications, software versions, IP address, and app performance data, and describes encryption, access controls, security assessments, and certified payment providers. Technical support responses may be delayed due to high ticket volumes.
