Piper

What is Piper?

Piper is a lightweight graphical front‑end that talks to the ratbagd daemon to adjust DPI, profiles, LED colors and button mapping on supported gaming mice. It was created by the libratbag developers to give Linux users a single‑pane interface similar to Logitech’s G Hub. The project is mature, with regular releases; the latest version 0.8 was published in September 2024.

The tool is aimed at gamers and power users who want fine control over mouse settings without editing config files by hand. It supports a wide range of devices, especially those that ratbagd already supports.

Compared with the Windows G Hub, Piper feels more lightweight and Linux‑native. It lacks some of the flashy themes and cloud sync features of G Hub, but it provides a straightforward, consistent workflow that works across distributions.

Best for: Gamers who want a native Linux mouse configuration tool without the extra features of proprietary software.

Key features of Piper

• Adjust DPI per profile
• Create and delete profiles
• Set per‑button actions
• Configure RGB LED colors
• Export and import configuration files
• Supports multiple mice at once
• Runs on Wayland and X11

Tips for Windows users

When moving from G Hub, note that Piper uses ratbagd’s JSON config files, not G Hub’s proprietary format. There are no direct import tools, so you’ll need to re‑create profiles manually. The shortcut keys are the same as the mouse buttons; you can assign them in Piper’s button mapping dialog. Workflow is simpler: open Piper, tweak settings, and the changes apply instantly via ratbagd.
