I'll probably open source it in the future, there's a lot of code there, and not much money to be made in Solitaire. I did extract some of the best general parts of the app (the admin, authentication, etc) into a project template I call Boilerplay (https://github.com/KyleU/boilerplay). If anyone's interested, I could also publish my pipeline to turn the Scala.js webapp into native apps for OSX, Windows, Linux, iOS, and Android.
