OpenLogi is a local-first, open-source configuration tool for Logitech peripherals, enabling button remapping, DPI control, and SmartShift management via the HID++ protocol without cloud dependencies.
What the product does and how it is positioned
OpenLogi provides a native alternative to proprietary Logitech management software, focusing on privacy and local control. By communicating directly with hardware over HID++, it allows users to customize their devices without requiring an account or transmitting telemetry data.
The application utilizes a user-owned TOML configuration file to manage settings, supporting a variety of connection methods including Bolt, Unifying, Lightspeed, Bluetooth, and wired USB. It is designed for users seeking a lightweight, transparent interface for their Logitech hardware.
Source-supported ways to use the product
Users can remap physical buttons to specific actions, such as browser navigation, system shortcuts, or application launchers, tailored to their workflow.
The tool allows for precise control over pointer resolution and the behavior of the scroll wheel, including automatic switching between ratchet and free-spin modes.
OpenLogi functions by interacting directly with the HID++ protocol, which serves as the communication layer between the software and the Logitech device. This approach bypasses the need for cloud-based middleware, so that all configuration changes are written directly to the device or the local TOML file.
Checks to run with your own material and workflow
What was checked and when
Answers based on the source-checked product record
No, OpenLogi is a local-first application. It does not require an account, does not transmit telemetry, and functions without an internet connection.
The software supports Logitech devices that utilize the HID++ protocol, including those connected via Bolt, Unifying, Lightspeed, Bluetooth, or USB cable.
No, you must quit Logitech Options+ before launching OpenLogi, as both applications compete for HID++ access and only one can control the receiver at a time.
Your settings and button bindings are stored in a local TOML file on your machine, which you own and can access directly.
No, OpenLogi is not affiliated with Logitech International S.A. It is an independent, open-source project under active development.
