Performance and the deep level tweaking is exactly what I would worry about with a no-code app (much like with WYSIWYG UI editors you end up with inefficient oversized webpages). Generally having less control over the details results in the details needing to be overly complex generalizations.

Of course, maybe someone will solve that problem. (Or computers will get so powerful efficiency ceases to matter). It also doesn’t change that things like no-code could be great for people less programming focused to prototype ideas, or create scripts to run over data much like people have used excel for ages. It might just remain necessary to eventually pass the implementation onto a non-visual programmer when scaling the solutions up for production.
