Polychromatic

What Polychromatic is

Polychromatic is a free, open-source GNU/Linux frontend for OpenRazer that controls lighting and other settings on supported Razer peripherals. Its home page lists more than 210 supported OpenRazer devices, including keyboards, mice, mouse mats, and headsets. Users can adjust built-in effects, brightness, DPI, and polling interval, or create static and animated lighting mappings from pixels and frames for games, applications, or ambience. The app can display firmware versions and serial numbers and test individually addressable LEDs. A tray applet provides access to lighting and device settings when the desktop environment supports a system tray or indicators. Polychromatic also includes a troubleshooter for issues such as OpenRazer not working or devices not being found. It runs locally without cloud services or a login, and is licensed under GPLv3. Its focus is OpenRazer: support for other brands is not available, and the maker gives no ETA for it. Key remapping is not supported. The maker describes polychromatic-cli as deprecated and planned for removal in the next major version. Polychromatic and OpenRazer are not affiliated with Razer.
