What is OpenLogi?
OpenLogi is a free, open-source desktop utility that replaces Logitech Options+ for supported Logitech mice, keyboards, and cameras. It drives devices directly over HID++ 2.0, covering button remapping, DPI presets, SmartShift, battery state, and multiple transports including Bolt, Unifying, Lightspeed, Bluetooth, and USB. Configurations live in a plain TOML file, there is no account or telemetry, and builds are available for macOS, Linux, and Windows. The project is explicitly early stage and not yet stable, with per-app profiles, Flow, and some pairing features still on the roadmap. There is no visible pricing or revenue model on the website.
