Ha! I very recently started something for peppers (Capsicum)
https://pepperrank.com/
https://pepperscale.com/hot-pepper-list/
I feel like I remember using another one much more similar to your site a while back but I can't seem to find it. But pepperscale is really cool and has individual profiles for cultivars
"Slightly hotter than a Jalapeno" means very little when a Jalapeno is anywhere from 3,000 scoville to 60,000 scoville.
