A group of enthusiasts has pushed out OpenMouse, an open-source, browser-based control panel for gaming mice. It’s meant to replace the need for bulky vendor software when you just want to tweak a few things — for instance remapping buttons or changing DPI and sensor options without installing extra apps.
Because it talks to hardware via the WebHID protocol, the web app runs the same on Windows, macOS and Linux in any Chromium browser (so no OS-specific binaries). The UI already reports battery and firmware status. You can switch DPI, adjust polling rate and lift-off distance, and even use the Motion Sync feature; firmware checks are built in, too.
The project intentionally exposes only “safe” settings so you don’t accidentally bricked a mouse’s microcontroller. It works purely through the web UI — no drivers, no background services on the OS; set it up and move on. Offline support is planned (e.g., something like Wootility by Wooting), and while supported models are limited today, coverage should grow as contributors add devices.
