A native, local-first alternative to Logitech Options+, written in Rust. Remap buttons, drive DPI and SmartShift over HID++ — no account, no telemetry.
@aprilnea built something surprisingly awesome for Logitech hardware!
OpenLogi is an open-source Rust alternative to Options+ that talks directly to Logitech hardware over HID++ and UVC. It runs natively on macOS, Windows, and Linux, with the controls you’d expect from the official app and quite a few power-user extras.
The setup is nicely straightforward. Most things can be changed from the GUI, while the underlying config is just a plain config.toml file you can inspect, edit, or copy between machines. No account or telemetry required.
One small heads-up: quit Options+ before launching OpenLogi. Both apps need direct access to the same HID++ receiver, so running them together would naturally conflict.
Hey Product Hunt 👋 I'm AprilNEA, the person behind OpenLogi.
I bought an MX Master because the hardware is genuinely great. Then I installed Options+ — an account prompt, a background service, telemetry, several hundred MB — all so I could change what the thumb button does. My mouse settings shouldn't need a cloud round-trip.
So I wrote OpenLogi: a native Rust app that talks to Logitech devices directly over HID++. Remap every button (44 built-in actions), set DPI presets, toggle SmartShift, battery for every paired device. Bolt, Unifying, Lightspeed, Bluetooth or USB — macOS, Windows and Linux.
Two things I care about:
Your config is a file you own. Everything lives in a plain config.toml. Read it, edit it, diff it, copy it between machines. No sync service, because there's no account to sync to.
Nothing leaves your machine. No telemetry, and the update check is off by default.
What's honestly not there yet: per-app profiles (in progress), an Options+ importer, and Flow. If those are dealbreakers, it's not a full replacement yet — the roadmap is public.
If you use a Logitech mouse, tell me which model and what you'd bind to which button.
(Heads-up: quit Options+ / Solaar first — only one app can own a receiver at a time.)

Congratulations on the launch! I’ve only used this once in my life) Can you configure only Logitech, or any mouse?
Report
This is amazing, love finally having Linux support as well instead of having to boot to Mac to change configs.
Love that this is local-first with zero telemetry and no account, most peripheral software treats a mouse config as an excuse to phone home, so building it in Rust as open source flips that whole model on its head.
No account, no telemetry, and a plain config.toml I can actually inspect and copy between machines - that's the whole pitch for me over Logitech's own Options+ app, which always felt heavier than what it's actually doing. Native on macOS/Windows/Linux and written in Rust so it's fast to launch, not another Electron menu bar hog.
What needs improvement
The launch notes mention you need to fully quit Options+ before running this since both fight over the same HID++ receiver - a startup check that detects Options+ still running and tells you to quit it, rather than just failing silently or conflicting, would save someone a confusing first five minutes.
I don't want the official app running just to remap a couple of buttons and set DPI - it always felt like more background process and account nagging than the job needed. Open source and no cloud dependency also means it should keep working even if Logitech ever deprecates Options+ or drops support for an older mouse.
