At first I didnt quite understand the value of this deal, so took it for a spin, and I immediately got hooked :) Let me just start by saying this is SOOOO super sleek!!

Ran a few bugs intentionally and was shown an immediate and exact description of the bug that I had created. The debug feature is worth the price alone! Then I spun up a react project within seconds, (spun up meaning I clicked a button!) and a live preview was INSTANTLY there! no npm run start or anything. and there is virtually any hot frontend framework you can think of vue.js 3 is there! and a whole range of css frameworks including my personal favorite: tailwind css. Super pleased!!!!!!
