One obvious reason why Qt is less popular is the ability for companies to deploy web apps (non Electron, but in the browser). Many end users expect a desktop/mobile app to also be accessible using the browser.

I'd argue that QML is an order of magnitude easier to develop than any other web frameworks (yes, you do have to get familiar with it, and if you made some apps before you could re-use some essential, battle-tested components). I hope to maybe share/sell some of mine some day.

I'm not sure what to answer regarding the browser experience. WASM isn't really there, isn't it? I haven't had a chance to test it on my own apps yet tho. I recently had a thought that maybe that Qt Company should also target HTML/CSS/JS generation of a QML file. Another, more interesting thought would be for browsers to be able to process and render QML files natively (but that won't happen without substential market share).

So again: the chicken-and-egg problem.

Basically, nothing is going to improve until somebody rolls up their sleeves and does all the hard work for free and do better than Electron -- or a corporation will push for it, it's always one of both. Then everybody else will flock to them.

That's what I observed several times during my life and career.
