No, our customers use it internally. Not even sure if they will end up deploying it as a website or a windows application. Which is an advantage of egui i suppose. I just picked it because I don't know any html or javascript and it does all that stuff for you, so it is just a rust app you can browse to. My team didn't know much more JavaScript than I do and they seemed to like it fine, but not as well as something declarative, which it is not.
