ReachUC is able to run on Windows and Mac computers with a downloadable app or from a web browser that supports webRTC (such as Chrome). Both versions rely on WebRTC, the browser-based real-time communications framework. The difference between versions is that the downloadable application behaves more like other applications that run natively on a Mac or PC computer when interacting with the operating system. A Chrome browser need not be installed when running the downloadable version.
The default scheme used by the Windows desktop app when calling is reachuc.

When running as a stand-alone executable, the application looks like this:
