OpenMouse review
Free, open-source WebHID mouse control with broad settings and variable device support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenMouse is a browser-based control panel for configuring supported gaming mice. It targets solo users and small teams that want open-source control across Windows, macOS, and Linux without relying on a vendor-specific driver. Through WebHID, users can adjust DPI, polling rate, lift-off distance, RGB lighting, and button mappings. The project is available free of charge and is licensed under AGPL-3.0.
Its main strength is the breadth of mouse settings exposed in a browser: core sensitivity controls, polling, lift-off behavior, lighting, and remapping are handled in one interface. WebHID keeps the primary workflow cloud-based and avoids a native installation, while an optional local companion provides a path for devices that the browser cannot access. Supported-device status information helps users assess compatibility, and the software can also be self-hosted. Documentation and community channels form the listed support model.
OpenMouse is a good fit when avoiding proprietary utilities matters and the mouse is covered by its community-maintained protocol drivers. The trade-off is compatibility: device and feature support varies, and WebHID behavior depends on both browser and operating system. Users who need a predictable vendor-maintained utility, guaranteed access to a particular mouse, or a single native application may prefer an alternative designed around that hardware ecosystem. For supported devices, OpenMouse offers a focused set of controls without a license fee; for unsupported hardware, the setup path may involve the local companion and additional compatibility checking.
