Sorbet: Stripe’s Type Checker for Ruby
Stripe has published a technical deep dive into Sorbet, the type checker it built for Ruby. Authored by Jake Zimmerman, an engineer on the company’s developer productivity team, the piece walks through the rationale and implementation details behind the tool.
The article highlights Stripe’s focus on tooling that helps engineers work faster and more reliably at scale. Sorbet is positioned as a key part of that strategy, bringing static type checking to a language that was not designed with it in mind. Zimmerman explains how the project fits into Stripe’s broader engineering workflow.
The publication is accompanied by references to Stripe’s related engineering efforts, including a case study on migrating millions of lines of code to TypeScript and a piece on how the company builds interactive documentation with Markdoc. Both are cited in the same developer productivity and open source categories.
