Sorbet: A type checker for Ruby 3 you can use today!
summary
Sorbet is a fast incremental type checker for Ruby that Stripe builds, open sources and uses across a multi‑million‑line repo; a three‑engineer effort becomes required for every Stripe engineer and runs as editor autocomplete jump‑to‑def with red squiggles as you type. The project ships a browser sandbox sorbet.run sandbox, integrates with rails via sorbet‑rails and Parlour, and records real uptake — 800 pull requests and 135 contributors plus 117 typed gems — and reports faster feedback and fewer accidental breaks.
