Sorry don't meant to be rude and I understand there are tens of thousands of technologies to detect. Kind of expecting your engine to be able to detect front end JS frameworks easier than backends, at least for those popular JS frameworks. In case you not notice the site I'm pointing to is the home page of VueJS and you're showing them using a competitor tech.

We're on it. Thank you so much for bringing this to our attention.

Well, at least you've got the business-speak down and can fix your bugs quickly. That'll get you far, I think.

Haha, I'll take that as a compliment.

You will probably want to add GNU Social. I pointed it at my site https://kwat.chat and it came up with nothing.

Also, Wordpress doesn't seem to be detected, either, on my other website: https://johnrockefeller.net
