Once an app is installed locally it is more convenient to use - that is why it is so common for apps to replicate (or just wrap) websites.
If you are not interested in the self-hostable part there are lots of online converters.
Why on the front page? That question might also have a non-technical answer. What's going on in news and events? Who's been setting up file translators and then "Dude I have over 4,000 soundfiles, pictures, address-books..." ... "Whoah? Like. howdy manage that one?" ... "People just submitted it. Zuck fucks"
A WASM solution might not be the most performant but it will be an option.
As for the web not being a good application platform, that ship sailed 20+ years ago and at this point, it’s hard to find any “native” apps that don’t share at least some similarities or core components as web apps, even if it’s just for UI. Although I personally would rather have a good native Mac app than a mediocre web app, I’d rather have a well-written web app than a mediocre Mac Catalyst app, and in many cases, than running an iOS app on the Mac. And I often prefer a web app or app built with web technologies to “native” apps built with GTK or Qt.
