Logitech G HUB vs Polychromatic

Logitech G HUB is free software for configuring Logitech G gaming mice, keyboards, headsets, speakers, and other devices. Its basic controls include DPI settings, assignments, and LIGHTSYNC effects. The Games feature lets users launch and organize game libraries, including libraries from platforms such as Steam and GOG. KEYCONTROL provides keyboard configuration features, while LIGHTSYNC RGB supports custom animations, synchronized Logitech G devices, and Windows Dynamic Lighting. Mixline provides audio routing, mixing, and streaming tools; Streamlabs offers tools for going live, engaging viewers, and designing streams. Logitech G integration is available in Final Fantasy XIV, and LIGHTSYNC has appeared in Star Wars: Battlefront II and Battlefield 1. Account holders can upload and download settings through the G HUB Community Library. Logitech also offers steering-wheel and LED-illumination SDKs, which require G HUB. The software is listed for macOS and Windows and is compatible with recent versions of both, though the latest release notes state macOS Ventura support was dropped. With consent, it may collect usage, device, system, diagnostic, crash, and application activity data.

Polychromatic is a free, open-source GNU/Linux frontend for OpenRazer. It controls lighting and other settings on supported Razer peripherals, with the home page listing more than 210 devices including keyboards, mice, mouse mats, and headsets. You can adjust built-in effects, brightness, DPI, and polling interval, or create static and animated mappings from pixels and frames for games, applications, or ambience. The app shows firmware versions and serial numbers and can test individually addressable LEDs. A tray applet provides settings access when the desktop supports system-tray indicators, and a troubleshooter addresses problems such as OpenRazer failures or missing devices. It runs locally without cloud services or a login and is licensed under GPLv3. Polychromatic supports OpenRazer only; other brands are unavailable, and key remapping is not supported.
