In many cases there are no practical alternatives for slick UI/UX.
It's not exactly rocket science.
So then you only need to provide url to the users of your app, and they are ready to use it.
With distributing binaries it is much more complex story. And that's why projects using Electron get more and more popular, because they at least take part of this complexity away.
...no they don't. They're literally distributed the exact same was as native applications. They're developed differently, saving the developer time (theoretically), but they're distributed in the same old download-and-install (or just download and run) way that applications have been since forever.
They don't solve all of the problems, but they do solve two important ones. 1. The runtime is the same on all platform 2. They build installable binary packages for you
So only 2 is about distribution , and it is not a trivial task. If you have to make Installer for windows, DMG for macos and let's say deb and rpm for Linux.
I have a small opensource tool that I make, and I would say that building the installer for all the platforms have taken probably 20% of all the development time, and if you count in also the desktop integration code( like Explorer context menu for Windows) it's way more.
