So far I have yet to see a real practical use for no code, they all seem great in the demo's and get alot of hype but at the end of the day they take far more resources to maintain than a normal app and you end up having to have a programmer maintain after the end user quickly exceeds their ability to develop anything in a no code enviroment.

They either get Flustered and end up back in Excel, or the "app" gets handed off to IT / Development who get frustrated and start a project to rewrite in a actual programming environment
