Introduction

OpenLogi is an open-source project offering a native, local-first alternative to Logitech Options+. Written in Rust, it provides robust control over your Logitech mouse, enabling button remapping, DPI adjustments, and SmartShift management via HID++. A key focus of OpenLogi is privacy, operating without the need for an account or any telemetry collection.

It communicates with Logitech HID++ mice through a Logi Bolt receiver, or via direct Bluetooth or wired connections, bypassing the need for the official Logi Options+ software. The project includes two main components: a GPUI desktop application, OpenLogi GUI, which features an interactive mouse diagram and per-button action picker, and OpenLogi CLI, a command-line interface for headless inventory and diagnostics. All configurations are stored locally in plain TOML files, ensuring complete user control and data privacy. Currently, macOS is fully supported, with Linux and Windows support planned for future releases.

Installation

Before installing OpenLogi, it is crucial to quit Logi Options+ if it is running, as both applications compete for HID++ access, and only one can control a receiver at a time.

For macOS users, you can download the signed and notarized .dmg file from the latest release and drag OpenLogi.app to your /Applications folder.

Alternatively, you can install OpenLogi using Homebrew:

brew install --cask aprilnea/tap/openlogi

If you prefer to build from source, detailed instructions are available in the DEVELOPMENT.md file.

Examples

OpenLogi offers both a graphical user interface (GUI) and a command-line interface (CLI) for managing your mouse settings.

GUI Features:

  • Interactive mouse diagram with clickable hotspots.
  • Per-button action picker with 37 built-in actions and custom shortcuts.
  • DPI presets and SmartShift toggle.
  • Per-application profile overlays that auto-switch based on app focus.
  • Device carousel for switching between paired devices live.

CLI Usage:
For headless inventory and diagnostic subcommands, refer to the USAGE.md documentation. This provides a powerful way to script and automate mouse configurations.

Configuration:
All settings are managed through plain TOML files. For detailed information on how to configure OpenLogi, consult the CONFIGURATION.md guide.

Why Use OpenLogi?

OpenLogi stands out as an excellent choice for Logitech mouse users who value privacy, control, and a native experience. Here are the key reasons to consider it:

  • Privacy-Focused: No account is required, and there is absolutely no telemetry collected. Your data and settings remain entirely local.
  • Local-First: All configurations are stored on your device in plain TOML files, giving you full transparency and control over your settings.
  • Native Performance: Written in Rust, OpenLogi offers a highly performant and responsive application experience.
  • Comprehensive Control: Remap buttons, adjust DPI, and manage SmartShift without relying on cloud services or the official Logitech software.
  • Open Source: The project is open source, allowing for community contributions, audits, and continuous improvement.
