OpenLogi
⚡️ A native, local-first alternative to Logitech Options+, written in Rust 🦀
Remap buttons, DPI, and SmartShift over HID++. No account, no telemetry.
Options+ ? Try OpenLogi.
Remap buttons, drive DPI and SmartShift, and switch profiles per app — without a Logitech account, telemetry, or the official Options+ install. No cloud, plain TOML config; the only network calls are device-image fetches and an opt-in, off-by-default update check.
OpenLogi talks to Logitech HID++ mice over a Logi Bolt receiver — or a Bluetooth-direct / wired connection — without running Logi Options+. It ships two binaries:
- OpenLogi GUI — a GPUI desktop app: an interactive mouse diagram with clickable hotspots, a per-button action picker (37 built-in actions plus recorded custom shortcuts), DPI presets, a SmartShift toggle, per-application profile overlays, and a device carousel that switches between paired devices live.
- OpenLogi CLI — a CLI for headless inventory (
list) plus asset-sync and on-device diagnostic subcommands.
Everything is local: bindings live in a plain TOML file, button presses are remapped through the OS event tap, and DPI / SmartShift changes are written straight to the device over HID++.
macOS is supported today; Linux and Windows are coming soon — see Roadmap.
Roadmap
| Capability | State |
|---|---|
| Discover Bolt receivers + list paired devices (CLI + GUI) | ✅ |
| Bluetooth-direct / wired devices (no receiver) | ✅ |
| Battery percentage / charge state | ✅ (online devices) |
| Interactive GUI: carousel, mouse diagram, action picker | ✅ macOS |
| Button remapping via the OS event tap (side Back / Forward today) | ✅ macOS |
| 37-action catalog + recorded custom keyboard shortcuts | ✅ macOS¹ |
DPI control + presets + Cycle / Set-preset actions (HID++ 0x2201) |
✅ macOS |
SmartShift wheel-mode toggle (HID++ 0x2111) |
✅ macOS |
| Per-application profile overlays (auto-switch on app focus) | ✅ macOS |
| Launch-at-login + opt-in update check | ✅ (TOML only — no settings UI yet) |
| Gesture-button per-direction bindings | 🟡 configurable; hardware capture pending |
| Middle / mode-shift / thumbwheel button capture | 🟡 configurable; hook owns side buttons only |
| Linux / Windows event hook | ❌ stub (Unsupported) |
| Unifying receivers | ❌ (not yet in hidpp 0.2) |
¹ A few actions (e.g. the media keys) currently log their intended event rather than posting it — tracked as a follow-up.
Install
[!IMPORTANT] Quit Logi Options+ first — the two applications fight over HID++ access and only one can own a given receiver at a time.
Download the signed, notarized .dmg from the latest release and drag OpenLogi.app to /Applications.
Or install via Homebrew:
brew install --cask aprilnea/tap/openlogi
