What OpenLogi is
OpenLogi is a native, local-first alternative to Logitech Options+, written in Rust. It remaps buttons and controls DPI and SmartShift over HID++, with no account and no telemetry. OpenLogi's documentation says it reaches devices over Logi Bolt, Unifying, and Lightspeed receivers, Bluetooth, or USB. Nothing needs to run through Logitech's cloud. Bindings live in a plain TOML file you can read, diff and copy between machines.
MakeUseOf's Rob LeFebvre tried it after Options+ would not install on his new MX Master 4. That is his personal experience, and I haven't independently confirmed it. It does show why people look for alternatives. A Pinggy write-up from August described the project's appeal as a native app with no account and no 200MB installer.
What it covers
OpenLogi's documentation lists these mouse features:
- Per-app button bindings, gestures, and short and long presses.
- DPI presets and report rate.
- SmartShift and scrolling force.
- Scroll inversion and wheel resolution.
- Thumb wheel control.
- The MX Master 4 Haptic Sense Panel.
It is not mouse-only. The docs also list keyboards, Litra lights, UVC webcams and G733 headset battery and link state. That wider scope is where LeFebvre says it goes beyond Options+, since it also handles some G-series gear he says normally needs G HUB.
The project's changelog shows steady MX Master 4 work:
- The haptic panel was captured as a first-class control in the August 0.8.0 release.
- An Actions Ring haptic reliability fix landed in the same history.
- A press-force setting for the panel arrived in a later beta build.
LeFebvre says his Actions Ring buzzes on each of its eight actions. That is one reviewer's experience, not a compatibility test.
Windows 11 haptics need Logitech's firmware
The mouse's own haptics and Windows 11's native haptic signals are different things.
Logitech's firmware notes say version 27.3.19, released March 30, 2026, added native advanced haptics integration for the MX Master 4 on Windows 11. It requires:
- Windows 11 with the March 2026 update or later.
- The latest MX Master 4 firmware.
- If you connect through a Logi Bolt receiver, up-to-date receiver firmware as well.
Logitech's troubleshooting page gives the Bolt receiver update steps, and they run through Options+:
- Plug in the Bolt receiver and keep it connected throughout.
- Make sure the MX Master 4 is paired to it.
- Open Options+ and click Settings.
- Under General Settings, click CHECK FOR UPDATE.
- Follow the on-screen prompts if an update is offered.
OpenLogi's comparison table, as reported, says it does not do firmware updates. Even OpenLogi fans may want Options+ installed for this. LeFebvre says he plans to keep it for firmware only.
Microsoft's developer documentation adds some context. The haptics API needs Windows 11 SDK 10.0.28000.1721 (March 2026). Some waveforms need 10.0.28000.1839 (April 2026). The MX Master 4 is listed among supported devices. That SDK requirement is for developers, not an end-user install step.
OpenLogi versus Options+
| Area | Options+ | OpenLogi |
|---|---|---|
| Platforms | Windows and macOS | macOS, Windows and Linux |
| Account | Needed for cloud backup | Not needed |
| Settings backup | Cloud, with an account | Copy the TOML file |
| Firmware updates | Yes | No |
| Smart Actions and Flow | Yes | No; Flow is on the roadmap |
| Import Options+ settings | Not applicable | Not yet |
| Haptics | Intensity plus Marketplace plugins | Panel control, ring haptics, press force |
The platform row comes from OpenLogi's own documentation, which says Options+ ships for macOS and Windows only. The rest is the MakeUseOf comparison.
Setup and cautions
- Quit Options+ first. The docs say the two apps fight over HID++ access and only one can own a receiver at a time. On Linux the same applies to Solaar. This is a device-access conflict, not a reason to uninstall Options+.
- Windows is the newer port. The developer says it has more rough edges than macOS. The README lists Windows 11 as the tested environment on x86_64 and arm64. Pinggy advised keeping Options+ around until you've confirmed your device and mappings behave.
- It is still pre-stable. The project warns that features and config may change. The docs describe the v0.8.15 release from October 20, 2026, and the changelog shows beta builds since.
- Packaging. Windows downloads come as an .msi installer or a portable .zip. According to the repository, releases include minisign signatures and a checksum file. That helps verify downloads. It is not a security audit.
- Licensing and independence. The code is dual-licensed Apache 2.0 or MIT. The project says it is not affiliated with Logitech.
MakeUseOf also mentions X-Mouse Button Control as another Windows remapping option. It says that tool does not handle haptics or SmartShift. I haven't verified that claim independently.
Who should try it
OpenLogi suits people who want local, account-free control, a config file they can version, or Linux support. It also suits anyone locked out of Options+. It does not replace Logitech's software for firmware, Flow, Smart Actions or importing old profiles.
A sensible Windows setup:
- Update the MX Master 4 firmware, and the Bolt receiver if you use one, through Options+.
- Quit Options+.
- Run OpenLogi for day-to-day mappings.
Back up the TOML file, since the project says config may change between releases.
