> It would be a totally different thing if it could run Rails, which is one of the things I do in my job. At https://heiioncall.com/ https://heiioncall.com/ we combine the two and use Rails for the human-facing parts, and Crystal for the machine-facing parts (inbound API server calls, and outbound HTTP probes). For us, the number of machine-facing requests per second is so many orders of magnitude higher than human-facing requests that Crystal's performance and lower footprint is valuable there. While on the other hand, the conveniences of Ruby on Rails are still great for a conventional human-facing web and mobile application.
