Hi @LS_9776545 ,
only client side.
When a project is scanned it will be downloaded from Experience Service (or it is already loaded for offline viewing) and then the project is started it will call the <startView>.js javascript file. By default the Start view in a new project (so far it is not renamed) is named Home -. When the home is started then it calls Home.js.
The only thing which is called on server side are some Thingworx services which refer in the external data section of Vuforia Studio or you can call some rest api form any servers so far there is no CORS issue.
