> That's not what Electron is
I mean...isn't it?
Forget the idea of what it's used for and just look at how it works. It's a framework for making apps that uses Chromium for rendering and a Node backend. Strip off the Node backend and you're left with Chromium.
And Chromium on its own is a web browser. Electron just doesn't show the controls for it.
As far as I'm concerned, Electron is a featureless web browser with a backend added to do things a browser normally can't do on its own, like reading local files without presenting a dialog.
