Happy Crystal user and code contributor here. (Also created https://github.com/compumike/crystal-docker-quickstart https://github.com/compumike/crystal-docker-quickstart in case you want to try Crystal without installing anything.)

As far as companies using Crystal: - We’re using it happily in production at Heii On-Call https://heiioncall.com/status https://heiioncall.com/status - Kagi is using it for their search engine backend https://news.ycombinator.com/item?id=32687071 https://news.ycombinator.com/item?id=32687071 - Other companies using it list: https://crystal-lang.org/used_in_prod/ https://crystal-lang.org/used_in_prod/
