Funny, from non-dev roles I'd probably put spreadsheets as the the platform for "no-code app dev".
Or rather, the platform for "this is the only b*d tool IT have allowed me to run, and no, I don't have a spare year for them to scope out what could be bodged by a couple of VBA scripts, and doing so would very obviously make my job better. So, for good or evil, it's going to be bodged with a couple of VBA scripts."
I feel like there's a lesson there, though I could be wrong. (Also not sure if that counts as "no-code")
Oh, and seconding the general consensus that websites that flash irrelevant notifications at me are pretty much an instant, hard "no".
