Going to be quite a bit heavier than that if you run it on a different CPU architecture though. And even if you’re not running on mobile, Apple still opened that can of worms a few years back. Linux too, I guess.

Honestly, I don’t mind HTML for a UI. It resizes nicely to fit a large number of devices. It looks pretty much the same no matter what you’re running it on. But it should just be that, a UI layer. Otherwise the solution you were looking for was a website, and not a dozen 500MB chunks of Chrome installed around my PC.
