All these companies have given up on the gold rush long ago and are just slinging fancy shovels.
When you hit the boundaries of what Hyperview can do, you're going to need to dig into some of the details, but mayhaps you don't need those features. Either way, it's an interesting project, but like everything else it's going to have _some_ drawbacks

However, this warning statement should be in bold at the top: "If your app relies on offline data or local computations, Hyperview won't be the right choice."
For that reason, I lean toward https://volt.build/
Volt looks great, but $15/mo. for the basic plan, $37/mo. for the pro plan that you likely need for the ad hoc builds alone (unless you test in prod).
