Is there an easier way to open a localhost website in an InDesign tab than a CEP extension?

Can it be done by using the default browser engine and window as an iframe, without implementing the Chrome engine clone into the tab or extension?

I want to use TiddlyWiki as a drafting tool in InDesign.

Can I embed an iframe in a tab and run a localhost website in it?

Is there any existing extension that is a web browser in a tab, for InDesign?
