We use it in production for our products at https://ark.fm and are actively working to move all of our Rails apps over to Crystal which ironically this framework looks great and may be a good choice for us. (Thank you to the author!)

Our email service runs an image proxy (to hide your IP from email trackers) with probably about 30-50 lines of code in Crystal that's been in production for multiple years and it just works.

Current project (in the cloud hosting space) that will heavily use Crystal for backend management and WASM which was recently introduced into Crystal and is a game changer for our use-case.

Also wrote a command-line tool with it and it feels like I'm cheating at how easy it is to do so.

Coming from the Ruby/Rails world where you have to cap deploy/bundle etc to push to a production server and hoping nothing breaks on dependancies makes Crystal's single binary deploy a breath of fresh air...not to mention the performance. We run our own hardware so being able to (eventually once we've moved over fully to Crystal) run the same workloads on LESS hardware with electric prices spiking is financially attractive.

As you can tell I'm a fan boy. I'm betting heavily on Crystal and going all in with our stack.

Did I mention it is fast?
