This looks like a shameless clone of shadcn/ui plus you're charging money for it.
In fact, that could even be the headline of the website: Want to use shadcn but don't want to rewrite your application in React? Use Shade/Bs!
I wanted to use shadcn/ui for a project, but I wasn't using React. I thought that was a shame, so I built one for my preferred stack, Bootstrap+net/http+html/template+htmx.
So its fundamentally a different architecture better suited for template based web applications. Like Django or Rails or Go html/template. It serves a completely disjoint market.
Thanks a lot for this understanding response, I'm still pretty new to this.
