Why wouldn't figma be considered a crud app?
It’s still basically adding and updating things in a DB no?
With some highly complex things like rendering, collab and stuff.
(Fair question btw)
Custom text editing and rendering is really hard to do well.
Making everything smooth and performant to the point it's best-in-class while still adding new features is... remarkable.
(Speaking as someone who's writing a spreadsheet and slideshow editor myself...among other things)
The custom text rendering bit alone should have been a good cue for this distinction.
But sure, I’m being too pedantic here I suppose.
If you want to know how tough realtime editing is, try making a simple collaborative drawing tool or something. Or an online 2 player text adventure game
Theres a reason tutorials for those arent common
