I'm skeptical this would work with crawling for anything other than the most basic toy websites. How can this identify components that use generated class names (any css-in-js, css modules, etc)? Can it pull prop usage out? I gave it a try on just our public login page and it said "no pages found" - perhaps it doesn't work for single page apps?
