The replacement Logitech does not provide
OpenLogi exists because Logitech Options+ leaves two obvious openings. It does not support Linux, and users on supported platforms must accept a much larger official software stack than many people want for changing mouse buttons. OpenLogi talks directly to HID++ devices through Bolt and Unifying receivers, Bluetooth, or USB. It stores settings locally in TOML, asks for no account, and reports no telemetry.
The project is broader than a button-remapping script. A background agent owns device communication and the operating-system input hook. A native GPUI application connects to that agent and presents device images, clickable controls, action pickers, DPI presets, SmartShift settings, battery state, lighting, and application profiles. A CLI lists devices, downloads assets, and runs feature and control diagnostics. Separating the agent from the interface lets settings continue working after the window closes.
Better controls, especially on Linux
The strongest reason to choose OpenLogi is that it treats Linux as a supported desktop rather than an unsupported build. Release assets include Debian, RPM, Arch, ARM64, and x64 packages. They install udev rules for access to raw HID, virtual input, and Logitech input nodes without running the app as root. A systemd user service keeps the agent available, and NixOS users get a module that configures the package, permissions, and graphical-session service together.
On all three platforms, users can remap buttons to built-in actions or custom keyboard shortcuts. Gesture directions are not restricted to Logitech's dedicated gesture button; middle, back, and forward buttons can receive their own directional bindings where the device supports capture. DPI presets and actions can set or cycle sensitivity. SmartShift controls cover wheel mode and sensitivity, while native scroll inversion and static keyboard lighting work on supported hardware.
Plain TOML is a real advantage for people with several machines. Configuration can be diffed, backed up, and copied without reverse-engineering a private database. Per-application overlays make one physical button behave differently in a browser and an editor. The caveat is clear in the roadmap: automatic profiles on Linux currently cover X11 and XWayland, not native Wayland applications.
Privacy claims are refreshingly specific. Bindings and device writes stay local. Device-image fetching is the only automatic network request enabled by default, while update checks and downloads require a request or opt-in. People with a strict offline policy should prefetch or forgo device art.
Installation is polished, not invisible
Mac users can install a signed, notarized disk image or use the official Homebrew cask. The minimum is macOS 13. OpenLogi needs Accessibility and Input Monitoring access because it captures and injects input, and a recent release added a startup permission request after fresh installs could otherwise fail to discover any device.
Linux packages handle the rules, but Debian, Fedora, and Arch users must enable the agent's user service. NixOS automates that part. Windows offers signed per-user MSI installers and portable archives for x64 and ARM64. The portable GUI and agent must stay beside each other. Windows support has been tested on Windows 11 hardware, but the README calls it the newest port and warns of additional rough edges.
Every platform shares one non-negotiable step: quit Logitech Options+ first. Both programs want ownership of the same receiver, so running them together can make device behavior and diagnostics misleading. This is a replacement trial, not a companion installation. Keep the official installer available until OpenLogi has survived sleep, reboot, device reconnect, and every mapping you use.
Device support is not one checkbox
HID++ exposes capabilities that vary across products, firmware, receivers, and connection modes. OpenLogi can discover a device while still lacking a specific control. The roadmap labels gesture capture, thumbwheel behavior, lighting, and several settings as capability dependent. That honesty is useful, but buyers should search the issue tracker for their exact model and transport.
Two current reports show the difference. Issue 651 says the MX Ergo S wheel's left and right tilt directions are not exposed as independently assignable controls, even though ordinary horizontal scrolling uses the hardware. Issue 653 provides a detailed v0.7.1 report in which native Back and Forward mouse actions fail on Linux with an MX Master 4 over Bolt or Bluetooth. It identifies both event-code and HID++ capture problems. These are bounded reports, not proof that all side buttons or Linux connections fail, but they affect common reasons to install the app.
Exceptionally active, still explicitly unstable
OpenLogi was pushed on August 16, 2026, one day after release 0.7.1. Ten releases landed between July 18 and August 15, including several on the same day. Issues and pull requests were still being opened and updated on August 17. GitHub's combined open count includes both, so it is a measure of a busy device matrix and development queue, not 147 confirmed bugs.
The velocity is reassuring when a new operating-system or device problem appears. It is also a reason to pin a working release. The README opens with a warning that features and configuration may change, and the version remains below 1.0. Rapid packaging does not create a stability promise.
Documentation is unusually strong. The main page names platform limits, permissions, automatic network behavior, package steps, component boundaries, and device-dependent features. Separate usage, configuration, Linux installation, and development guides go deeper, while the CLI produces diagnostics suitable for issue reports.
OpenLogi is already the first option I would test for local Logitech configuration across several desktop operating systems. Linux users gain the most. Just judge it by the exact controls it handles on your desk, not by the length of its roadmap, and keep a known-good configuration and installer before each upgrade.
