Related to that, is there anything that allows to completely save the state of a modern website with all of the fetch requests and websocket related stuff it fired off?

I just want an ability to save and reopen exactly what I'm looking at. There are some cool websites which will eventually go down and I want to preserve an interactive snapshot of them.

This won't work for WebSockets, really websites that use WebSockets require some interaction to generate the transmitted message which is often dependent on the servers response. Private websites, or websites that require a login are hard - but it can be done. Would suggest HTTrack.

But it's not impossible to have some tool that records all of those interactions to reproduce later. A smart enough tool could record everything since you open the site until you click save. It would not reproduce the functionality that is backend dependent, but iy sure can replicate the dom, etc. Am I missing something?

Yeah - but there's a LOT of variables that come into play for something like that. It'd likely be easier to either record it with something like BugReplay.com or video.

This is part of a webtop I built called qKast (https://qkast.com) In fact the chrome extension https://chrome.google.com/webstore/detail/qkast/eliofljjghgd... let's you mix and match live components of webpages and make "living" snapshots, further then that though - they're not i-Framed so you can use an assortments of widgets to modify the contents and look of the components as well as broadcast the whole webtop live.

I haven't used it so I'm not sure that it does everything you want, but take a look at https://webrecorder.io/
