I did some steps to do do a "TNoGUIApplication = class(TCustomApplication)", but looking into the "Forms" code (that implements the LCL "Application = class(TCustomApplication)", I saw that the connection to the underlying Graphics system is not direct, but done by kind of dynamically linking to a "Widget Type", and looking in the project options, I see that the Widget Type can be selected independently of the source code and creation method of the Application. Here even we already have a selectable widget type "NoGUI (Pre-Alpha)". Obviously somebody already once started such a project.

It works perfectly. You can use it to compile any fcl-web application
against. So that there are no dependencies on external gui-libraries
(like gtk, qt etc)
