OpenLogi provides open‑source Logitech mouse configuration tool

OpenLogi is an open‑source application that enables users to configure compatible Logitech mice through the HID++ protocol without installing Logitech’s proprietary Logi Options+ software. It runs locally on macOS and Linux, offering a graphical interface for button mapping, DPI adjustments, SmartShift control, and a command‑line interface for diagnostics and device management.

The tool emphasizes privacy by eliminating account creation and telemetry, but it currently does not support Windows operating systems or Logitech’s Unifying receivers.
