    On-Premise currently only supports Windows & Ubuntu variant distributions but source-code is readily available.

    Includes convenient ~200mb client installer & branding customization features.

    Project is on hiatus as of about a month ago (Aug 23, 2021) due to change in dev personal living arrangements.

    Heavily recommend supporting this one and all his endeavors, this sort of thing only comes around once in a blue moon!
