Indeed, at this moment, having access to our login endpoints is a mandatory requirement. The team is discussing the possibility of implementing a "Viewer" mode functionality that won't require login (to load SAZ or preview saved sessions). Still, the talks are in the very early phase. I am making this a feature request, and any related information about a possible offline solution will be posted here.
A Viewer would be great. This was also a feature in Fiddler Classic
Why is there a requirement for being online at all? This is no option in an enterprise environment, in particular not when you buy the product. A gazillion other commercial applications work without some login online and have done so for many years.

Sometimes, you just want to be able to load up a SAZ without any internet connection (i.e. on a plane).
Is that possible with Fiddler Everywhere or is a login required?
