It's a nice idea, but when I tested it with several websites, I got mixed results or none at all.
I understand that there are also security tool that hides some used plugins and CMS so it's possibly not entirely Rayst fault.
Pretty design, but didn't help me reveal the stack of websites as much as I needed. Having company information is cool but not essential. Will stick to Wappalyzer unless it gets more fully featured.
