Nice project! You state that your looking for someone to opensource it. Whats keeping you from just gitlab pushing your stuff? :) Would possibly be interested in recreating this.
Time, I would like to polish all the stuff a do it properly, but have not time for that. Also there are still some things TBD.
Open source happens sometimes because people are willing to just git push things that are half finished or even garbage. You should not feel bad about doing it!
Until all the requests for help start coming in..
In my experience you have to be very successful to get anyone to pay attention at all.
