UnityHubNative is a lightweight C++ / wxWidgets alternative to the unnecessarily heavy official Unity Hub, built using wxWidgets. It uses native widgets on all platforms instead of heavy web components like the official Electron hub.
UnityHubNative launches many times faster, uses far less memory and CPU, and is a fraction of the total size of the official Unity Hub.
UnityHubNative does not have every feature that the official hub has, but it has most of the commonly-needed features. UnityHubNative serves as a shortcut to get into your projects faster.
