We use Crystal a lot too at Crunchy Bridge. It is used for all of the on-instance programs, the per-region monitoring service, as well as the customer CLI. I'm a big fan of Crystal, and wrote the postgres driver for the language :)

However a main reason we used Ruby was for the production REPL which lets us manage our entire server fleet with like 1/3 of the staff we'd need otherwise.

Amen to that. We reached $2M ARR as 3 engineers at Missive [1]. As the CTO, I can tell life wouldn’t quite be the same without the ability to save the day in the production console at the speed of light.

I'm intrigued. Are you talking about the `rails console` REPL? How did that allow you to manage your fleet with 1/3 staff?

thank willl.

When I investigate in Crystal I found your github and your Posgres driver.
