OpenLogi.net - an Options+ replacement for Windows. Open source, no cloud, no background bloat
I've been building openlogi.net , an app for controlling Logitech mice and keyboards on Windows — and it's at a point where I'd love for people to try it.
It talks to your devices directly over HID++ (Bolt/Unifying receiver, Bluetooth, or wired), so everything stays on your machine: no account, no cloud sync, no telemetry.
The porting story: this began as a port of the excellent Rust project AprilNEA/OpenLogi. The original leads on macOS and Linux - Windows is an early, untested preview there. I'm on Windows, so rather than bolt Windows support onto a Rust/GPUI codebase, I rewrote it in C# / .NET + Avalonia.
Because the whole thing is built around Windows first, it's grown more capable on Windows than the original's Windows preview — fuller device support, RGB lighting (per-key colors and effects), onboard and per-app profiles, multi-host switching, and a proper installer. It's an independent project, but huge credit to the upstream OpenLogi for the foundation and the reverse-engineering work.
What it does:
- Discovers your devices + shows battery level
- Button remapping
- DPI control + presets
- SmartShift (wheel ratchet) tuning
- RGB lighting — colors, effects, brightness
Why you might like it:
- Small + self-contained — ~16 MB installer (or a portable zip), and you don't need .NET installed
- No account, no telemetry, fully open source (MIT)
- Installer and a no-install portable build on the releases page

I've tested it on the hardware I own, and since Logitech's lineup is huge, I'd genuinely love to hear how it runs on your device — open an issue with your model and what worked. One quick tip: close Options+ first, since both apps want to talk to the device at the same time.
