Nocode/lowcode is excellent for company internal apps & GUIs. Imagine things like barcode/QRcode scanner app for warehouse that just needs to send an HTTP call somewhere. Stakeholders/business people might be able to complete some smaller apps & views & GUIs themselves an no need to wait for engineering support.

It's likely never going to produce production quality web UIs for sites that have millions of consumer users where everything has to be optimised by hand but that's not really most use cases or the case for NoCode/LowCode.
