I'm by no means an expert, but happy to help where I can!
I use A1111. It's a very easy to use (and setup) way of accessing Stable Diffusion, gives you loads of control/settings, and is all locally hosted.
Here's the installer (or google A1111, I wouldn't trust a stranger on the internet either!) https://github.com/EmpireMediaScience/A1111-Web-UI-Installer
I don't recognize that fork of it - what are the differences there? I've been using vladmandic's fork for a while and found it quite good. I still have the original kicking around as well, but don't use it much.
