Unfortunately the Qt demos all take 8-10 seconds to load on a phone for me and several of them fail with out of memory even on high end devices like a Pixel 4 XL. Certainly I'd expect a Pizza Ordering app to work on mobile (and to not show a flash style loading spinner for 10 seconds). WT is doing all the logic server side so the client ends up being lighter weight and will work on more devices, and with better performance.

The Qt port for WebAssembly still has zero accessibility support, e.g. for blind people with screen readers. Assuming Wt is using standard HTML form controls, it shouldn't get in the way of accessibility. Of course, the app developer still needs to follow good accessibility practices, such as labeling images and not conveying information through color alone.

  While it is unfortunate, in 30 years of software development that has never been a requirement for the projects I have been involved unless the customer was some kind of governmental institution and made it part of the acceptance criteria. So unless there is a mindset change, that will keep happening.

    Seriously? Not just govs, but just about all large orgs serving web apps have accessibility requirements.

      Depends pretty much on your jurisdiction, then in many countries even if that is required by law, trying to make a lawsuit out of it will lead nowhere, as most countries aren't so lawsuit friendly as US. Assuming that there is a court willing to hear it, probably by the time it reaches the first audience there is a new website in place.

    Maybe the mindset change has to come from developers. That is, maybe developers are obligated to implement accessibility regardless of what the customer says. Remember, this isn't just a checkbox on a compliance form; it determines whether some people can do their jobs, complete their education, access essential services, etc.
