Overview
OpenLogi is a local-first, open-source alternative to Logitech Options+ that gives you complete control over your Logitech mouse via HID++. It runs on macOS, Linux, and Windows, and it lets you remap buttons, adjust DPI, and toggle SmartShift without any account or telemetry. All settings are stored in a plain TOML file that you own.
