I was gearing up to be irritated at seeing "no-code", but this was apparently built using a glorified WYSIWYG editor. That's really impressive, especially given how close it looks to what you set out to imitate. Nice work!
Isn't "glorified WYSIWYG editor" basically what nocode is? Why would the terminology decide your mood when the two are basically synonymous in this context? Bubble (which been used for building this) describes themselves as a nocode tool quite literally ("The best way to build web apps without code") but because you see it as a WYSIWYG your irritation disappeared?
I haven't deployed anything myself on Bubble (only tried their editor briefly) but since this submissions URL is reggit.bubbleapps.io I'd wager that yes, Bubble does handle everything for you once you've actually built your app in their editor.
