> **Options+ ? Try OpenLogi.**
Remap buttons, drive DPI and SmartShift, and switch profiles per app โ without a Logitech account, telemetry, or the official Options+ install. No cloud, plain TOML config. By default, device-image fetches are the only automatic network calls; update checks and downloads run only when you request or opt into them.
---
## What it is
OpenLogi talks to Logitech HID++ peripherals over Logi Bolt and Unifying
receivers, Bluetooth-direct connections, or USB cables โ without running Logi
Options+. It consists of three components:
- **[OpenLogi GUI](crates/openlogi-gui)** โ a GPUI desktop app: an interactive mouse diagram with clickable hotspots, a per-button action picker (built-in actions plus custom keyboard shortcuts authored in the TOML config), DPI presets, SmartShift, per-device scroll inversion, RGB keyboard lighting, per-application profiles, a live device carousel, and a Settings window localized into 20 languages.
- **[OpenLogi agent](crates/openlogi-agent)** โ the background service that owns the input hook and all device I/O. The GUI is a pure IPC client and starts the agent when needed.
- **[OpenLogi CLI](crates/openlogi-cli)** โ a CLI for headless inventory (`list`) plus asset-sync and on-device diagnostic subcommands.
Everything stays local: bindings live in a plain TOML file, the agent remaps
button presses through the OS input hook, and writes DPI, SmartShift, scroll,
and lighting changes straight to the device over HID++.
macOS, Linux, and Windows are supported. Windows is the newest port: it has
been validated end-to-end on Windows 11 hardware, but may still have more rough
edges than the macOS and Linux builds; see [Roadmap](#roadmap).
## Beyond Options+
Things OpenLogi does that Options+ won't:
- **Run on Linux.** Options+ ships for macOS and Windows only. OpenLogi treats
Linux as a first-class platform: evdev/uinput hook, udev rules, a systemd
user unit, and `.deb` / `.rpm` / `.pkg.tar.zst` packages.
- **Move the Gesture Button.** Pick which physical button owns the gesture
role โ the dedicated Gesture Button, middle, back, or forward โ with per-direction swipe
bindings, or turn gestures off entirely. Options+ pins the gesture role to
the dedicated Gesture Button.
- **Keep config in plain text.** Everything is one TOML file you can read,
diff, version-control, and copy between machines.
- **Script it.** A real CLI: device inventory, asset prefetch, and on-device
HID++ diagnostics (feature/control dumps, DPI / SmartShift round-trips, and
keyboard lighting checks).
- **Stay light.** Native Rust + GPUI binaries โ no Electron suite, no resident
updaters, no account, no telemetry.

| Battery percentage / charge state | โ
(online devices) |
| Interactive GUI: carousel, mouse diagram, action picker | โ
macOS + Linux + Windows |
| Button remapping via the OS input hook | โ
macOS + Linux + Windows |
| Built-in action catalog + custom keyboard shortcuts (TOML-authored) | โ
macOS + Linux + Windowsยน |
| DPI control + presets + Cycle / Set-preset actions (HID++ `0x2201`) | โ

| SmartShift wheel: mode toggle + sensitivity + permanent-ratchet panel (HID++ `0x2111`) | โ
|
| Per-device native scroll inversion (HID++ `0x2121`) | โ

| Interface localization (20 languages: da, de, el, en, es, fi, fr, it, ja, ko, nb, nl, pl, pt-BR, pt-PT, ru, sv, zh-CN, zh-HK, zh-TW) | โ
|
| Linux packaging: udev rules, systemd unit, `.deb` / `.rpm` / `.pkg.tar.zst` | โ
Linux |
| Gesture-button per-direction bindings + live capture | โ
(device capability dependent) |
| Middle / mode-shift / thumbwheel button capture | โ
middle on all platforms; mode-shift / thumbwheel device dependent |
| Windows (agent, GUI, event hook, installer) | โ
Windows 11 hardware validated; newer port with ongoing compatibility polish |
Help improve the interface translations on [Crowdin](https://crowdin.com/project/openlogi).
ยน Media key actions use D-Bus MPRIS on Linux; a handful of macOS-specific actions have no universal Linux equivalent and are no-ops. Windows maps platform actions to native equivalents where available.
## Install
> [!IMPORTANT]
> Quit **Logi Options+** first โ the two applications fight over HID++ access and only one can own a given receiver at a time.
### macOS
Requires macOS 13 or later.
Download the signed, notarized `.dmg` from the [latest release](https://github.com/AprilNEA/OpenLogi/releases/latest) and drag `OpenLogi.app` to `/Applications`.
Or install via [Homebrew](https://brew.sh):
```sh
brew install --cask openlogi
```
The official Homebrew cask is the default installation path. To explicitly
track the latest GitHub release from `aprilnea/tap` instead:
```sh
brew tap aprilnea/tap
brew install --cask aprilnea/tap/openlogi@latest
```
`openlogi@latest` is maintained by OpenLogi's release workflow and may update
before the official cask autobump lands. Install either `openlogi` or
`openlogi@latest`, not both.
### Linux
Download the package for your distribution from the
[latest release](https://github.com/AprilNEA/OpenLogi/releases/latest):
```sh
# Debian / Ubuntu
sudo dpkg -i openlogi_*.deb
# Fedora / RHEL
sudo rpm -i openlogi-*.rpm
# Arch Linux
sudo pacman -U openlogi-*.pkg.tar.zst
```
Packages are published for both `x86_64`/`amd64` and `arm64`/`aarch64`.
The package installs udev rules that grant your user access to
`/dev/hidraw*` and `/dev/uinput` without `sudo`. After installation,
enable the background agent for your user:
```sh
systemctl --user enable --now openlogi-agent.service
```
See [docs/INSTALL-linux.md](docs/INSTALL-linux.md) for manual / source installs
and distros without systemd.
### Windows
Signed portable `.zip` archives and per-user `.msi` installers (x86_64 and
arm64) are attached to each release. Both ship the GUI (`OpenLogi.exe`)
together with the background agent (`openlogi-agent.exe`), which owns all
device I/O โ keep the two files side by side when using the portable zip, or
the GUI has nothing to connect to.
Windows support works and has been validated end-to-end on Windows 11 with
real hardware โ a wired keyboard and a Unifying-receiver mouse, including
install, in-place upgrade, and uninstall of the MSI. It is newer than the
macOS build, so if you hit a rough edge please
[report it](https://github.com/AprilNEA/OpenLogi/issues). The agent shows a
system-tray icon (Show Main Window / Quit) so the app stays reachable after
the main window is closed. To disable it on Windows, set
`show_in_menu_bar = false` in the TOML `[app_settings]` block and restart the
agent; the GUI toggle is currently macOS-only.
To build from source, see [DEVELOPMENT.md](docs/DEVELOPMENT.md).
