## Abstract

In June 2019, Stripe open-sourced Sorbet, a fast and powerful type checker for Ruby and a tool that has come to be indispensable for writing Ruby code at Stripe. We'll discuss why and how we built Sorbet, including how specific choices and tradeoffs affected its design and adoption, as well as the experiences we've had in adopting, using, and open-sourcing Sorbet, and where we plan to take Sorbet from here.
