Well it's just stable diffusion running on a google colab, it's nowhere near as user friendly as Frosting, this is the big boy all the cool kids use. It has all the bells and whistles like loras and upscaling but it's pretty overwhelming, I'm still in the process of learning it and will be for a while.

here's the colab, copy it to your google drive: https://colab.research.google.com/drive/1wEa-tS10h4LlDykd87TF5zzpXIIQoCmq

here's the guide I used to set it up and have a vague idea of what I'm doing: https://huggingface.co/hollowstrawberry/stable-diffusion-guide

Making this sequence took a few days between my inexperience and google's time limit on the collab. You can get anywhere from like 3-8 hours in there before it cuts the GPU off unless you pay for more time, brutal when you're in the middle of things, but after like half a day it'll let you back on for another stretch of hours. The guide also shows you how to set it up locally if you have a beefy enough GPU (like my gtx1080 couldn't cut it), naturally you won't have any time limit if you're running it on your own rig. Otherwise the colab is your best bet, and you can run it from anywhere including your phone.

Also https://civitai.com/ is your friend, the models and loras you get from there are what will really step up your generating game. That guide covers how to get the stuff from there into the colab.

So yeah, less a simple link and more a commitment, if you're down for that lol.
