This is a website I developed in Crystal for hosting API documentation for Crystal shards (aka gems, crates, libraries, etc). It's built in Crystal itself and is using Postgres, Kemal, the built-in doc generation tooling, and Lexbor. I've been working on this for a number of months and I'm proud of where it's gotten. All feedback welcome!

Happy Crystal user and code contributor here. (Also created https://github.com/compumike/crystal-docker-quickstart in case you want to try Crystal without installing anything.) In my opinion:
- Slow compile times are still a pain for iteration.
- The REPL / interpreter mode is still rough around the edges.
As far as companies using Crystal:
- We’re using it happily in production at Heii On-Call https://heiioncall.com/status
- Kagi is using it for their search engine backend https://news.ycombinator.com/item?id=32687071
- Other companies using it list: https://crystal-lang.org/used_in_prod/
Yeah, there's a GH issue thread here that I keep an eye on: https://github.com/crystal-lang/crystal/issues/5430
I figure whenever windows support lands will be a good time to give it a shot again.
