Aurora-RGB

Aurora-RGB is a free, open-source application that controls RGB lighting on keyboards, mice, mousepads, and fans, syncing them to real game events instead of just static colors or generic effects. It supports over 40 game integrations, including CS2, Dota 2, and League of Legends, driving effects like damage indicators, ability cooldowns, health and mana status, and team-color identification directly on connected hardware. The software works across all major RGB brands including Logitech, Razer, and Corsair, and also extends to WiFi-connected smart lights like Nanoleaf, Philips Hue, and Yeelight. All features are free with no paywall, and advanced users can build custom layers, interactive keyboard effects, and scripts on top of the built-in system monitoring for CPU, memory, and volume.

OpenRGB

OpenRGB is a free, open-source application that controls RGB lighting on PC components and peripherals from many different manufacturers through one unified interface, without needing each vendor's own bloated software running at the same time. It talks directly to supported motherboards, RAM, GPUs, keyboards, mice, and case fans over their native protocols. The project ships a lightweight GUI, but it can also run headless as a server or client so lighting can stay synchronized across multiple machines on a network, and its documented network SDK lets third-party apps and games trigger lighting changes. A plugin system adds extra effects, ambient lighting sync, and integrations with other lighting ecosystems on top of the core device list.
