Our verdict on Mouser
Mouser is open-source desktop software for remapping compatible Logitech HID++ mice on Windows, macOS, and Linux. It is aimed at solo users and small teams that want local control over programmable mouse buttons without cloud connectivity, telemetry, or a Logitech account. Its feature set covers button reassignment, application-based profiles, keyboard shortcuts, DPI, pointer speed, Smart Shift, scroll modes, and gesture-button swipe actions. Mouser also reconnects automatically after device power cycles.
The pricing model is straightforward: Mouser is free and distributed under the MIT License. There are no paid tiers to compare, so the full stated feature set is available within the open-source desktop application. Downloadable builds are provided for Windows, macOS, and Linux, making it suitable for users who work across those operating systems or want a self-hosted, local desktop utility rather than an account-based service.
Its strongest fit is Logitech mouse customization, especially for MX Master and MX Anywhere families. Per-application profiles and gesture actions give users a way to adapt controls to foreground applications, while sensitivity controls cover DPI and pointer speed. The trade-off is its narrow device focus: users looking for keyboard customization or broader peripheral management should choose a different category-specific tool. Support is oriented around community resources and documentation, so Mouser suits users comfortable with open-source software and local configuration more than buyers seeking a broader commercial support structure.
