OpenLogi is a native desktop alternative to Logitech Options+ for Logitech devices. It is written in Rust and is built around local control: the app remaps buttons, drives DPI and SmartShift over HID++, and stores bindings in a plain TOML file rather than in an account-backed cloud profile.
The product page emphasizes that changes are sent directly to the device, with no account, no telemetry, and no cloud dependency. It also states that signed builds are available for macOS, Linux, and Windows, with installation options including Homebrew on macOS and platform-specific installers for the other operating systems.
