Mouser replaces Options+ for Logitech mice

Mouser is an open-source, fully local Logitech mouse remapping app that aims to replace Logitech Options+ without the cloud, telemetry, or account friction. It is strongest on the MX Master family today, where it supports per-application profiles, gesture and button remapping, DPI/pointer speed control, scroll inversion, and automatic reconnect behavior, while keeping everything stored and processed on-device.

// ANALYSIS

Big picture: this looks like the kind of utility Logitech power users have been waiting for, especially if they want Options+ features without the usual bloat and background noise.

–Best fit for MX Master users who want app-specific mappings, gesture support, and DPI control with minimal overhead.
–The fully local design is a real differentiator: no cloud dependency, no telemetry, and no Logitech account required.
–It is more promising than “universal” remappers because it speaks HID++ and can sync settings back to supported devices.
–The main caveat is coverage: the MX Master family has the most complete UI, while other Logitech HID++ mice are still more best-effort.
