I never saw the pitch of crystal compared to Ruby with RBS.

  For me, the pitch is performance: Crystal would be several times faster, while using a tiny fraction as much RAM. In my use case for https://heiioncall.com/ https://heiioncall.com/ I ported a part of our system from Ruby to Crystal and we're seeing about ~10x faster throughput while using ~1/10th as much memory. That changes the operating economics drastically enough that, for example, Heii On-Call provides free website and API endpoint monitoring.

    Genuine question: if performance is a primary concern, why not choose Elixir?

    Genuine wondering, why Ruby Rails for the Website and not Crystal. Considering you are using Crystal for totalreturn ( big fan ) and heiioncall as well.
