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
