I tend to disagree here. The thing that makes writing business software take a long time (using code, to be pedantic), isn't the fact that it's in code -- it's the fact that the requirements are often so fast and complex that there's no way to capture them in the application without taking a good chunk of time. If you want an application that doesn't actually meet your requirements, but at the very least, exists, get a group of competent-enough engineers together and they'll be able to whip you something up pretty quickly, I reckon. About as quickly as non-techincal people would be able to make something of equal usefulness in a non-code tool.
If you have access to only engineers, why would they learn this new non-code tool? If you want an application that meets a very sparse, loose set of requirements, just get them to create it using their normal tools -- it won't take relatively long.
If you have access to both engineers and business folk, there's no reason to have the businesspeople write such a requirement-lax application using a non-code tool, since if all you really want is an MVP that doesn't really meet your requirements, get the engineers to do it -- I'm sure they'd be happy with the freedom to throw requirements out the window. And then when you want to expand on it and flesh out those requirements, the engineers don't have to port the whole thing over from whatever proprietary non-code tool the businesspeople could have used.
If you only have access to nontechnical people, you're kind of screwed. Sure, you can have business-savvy folks whip up an MVP using one of these tools, but then when you want to expand on it, what do you do? You need technical people somewhere in the pipeline to make this work. If you didn't have access to engineers in the first place, this is the juncture at which you could hire some to port the application, but is the technical debt you've introduced worth it?
I don't know -- tools like these seem to target aspirational nontechnical people who don't have the foresight to think two steps ahead.
