@delta @deltatouch @lk108 WebXDC apps work on only a few of the platforms I care about, I'd be careful about stating it runs on all platforms.
It's why I avoided really working with WebXDC, it can't (not properly) even run on the platform I need it to run on.
Ubuntu Touch is not a hard platform to target relatively speaking. Ofc UI work is hard, and there's specific challenges with mainline phones, but it is by no means an exotic platform. It's just Linux.
Not to discredit anyone's work here.
