Why it is worth attention

It offers a fully open-source, privacy-respecting replacement for Logitech's proprietary software, with features like multi-button gesture support and per-application profiles that are often missing in alternatives.

Who it is for

Logitech mouse and keyboard owners seeking to avoid Options+
Windows users who want advanced customization (gestures, DPI, RGB)
Developers interested in HID++ device control and C#/.NET desktop apps

Use cases

Remap buttons and create custom keyboard shortcuts for productivity
Set up hold-and-swipe mouse gestures for window management or media control
Adjust DPI presets and toggle SmartShift for smooth scrolling
Configure per-key RGB lighting and onboard profiles for keyboards

Strengths

Fully local with no Logitech account, cloud sync, or telemetry
Supports gesture mapping on any capable button, not just the MX gesture button
Provides both a GUI desktop app and a CLI for headless configuration
Self-contained release bundles the .NET runtime, requiring no extra dependencies

Considerations

Dongle (receiver) support may be unreliable; Bluetooth/wired connections are preferred
Conflicts with Logitech Options+, G HUB, or Logi Bolt app if running simultaneously
Under active development and not yet stable; features and configuration may change

README quick start

openlogi-net

📥 Download the latest release — installer or portable build.

A native, local-first alternative to Logitech Options+ for Windows. Remap buttons, set up hold-and-swipe mouse gestures, drive DPI and SmartShift, control RGB lighting, and switch profiles over HID++ — without a Logitech account, telemetry, or the Options+ install.

This is a C# / .NET 10 / Avalonia rewrite of AprilNEA/OpenLogi (originally written in Rust), focused on Windows.

What it is

openlogi-net talks to Logitech HID++ devices — mice and keyboards — over a Logi Bolt / Unifying / LIGHTSPEED receiver (including the Powerplay mat's embedded receiver), or a Bluetooth-direct / wired connection, without running Logi Options+. Everything is local: there is no account, no cloud sync, and no telemetry.

It ships two binaries:

OpenLogi.App — an Avalonia desktop app with an interactive device view, a per-button action picker, a gesture editor with per-direction actions and presets, DPI and SmartShift controls, RGB lighting (per-key colors and effects), per-application profiles, and a system-tray presence.
OpenLogi.Cli — a headless command-line tool for device inventory, on-device HID++ diagnostics, asset prefetch, and lighting/profile probes.

What it does

Discover devices behind Bolt / Unifying / LIGHTSPEED receivers and direct Bluetooth / wired connections, with per-device online state and battery level.
Remap buttons to a catalog of actions and custom keyboard shortcuts.
Mouse gestures — hold a button and swipe up / down / left / right for four actions, with a plain tap as a fifth. Works with the dedicated MX gesture button or any capable button (Middle, Back, Forward, the wheel-mode button) — several at once — with Options+-style presets (Windows & Desktops, Media & Volume, Arrange Windows…) or fully custom per-direction actions. See docs/MOUSE_GESTURES.md.
DPI control — read and set sensitivity, with presets.
SmartShift — toggle the wheel ratchet mode and
