Seems like there was a previous version of the engine that was written in Haxe [0]

> alpha - deprecated 2015~2016. unrelated to the new engine! view the new engine here - https://luxeengine.com/

Also, that old version used to be open source, but I think this new one isn't anymore. Old thread mentioned by @pvg still mentions being open source, but right now the repositories only have docs.[1]

It does still mention source here as well https://luxeengine.com/faq/#source-access

Sounds like they might be switching to a source-available model rather than an open-source model.
