Cubist launches 'Design Rules as Code' to sync tokens, tests and CI across teams

Design Rules as Code provides a declarative language to express constraints — spacing scales, responsive breakpoints, token relationships and component states — which can be executed in CI to prevent regressions. It integrates with common design systems and codebases.

The product offers a visual editor for designers to express rules without deep technical knowledge and a CLI for engineers to run checks in build pipelines. When a rule fails, the system surfaces a clear remediation path tied to the design artifact.

Cubist argues this approach reduces drift between prototypes and production, supports scalable designOps and minimizes expensive late-stage fixes. The company also released templates for common design patterns to accelerate adoption.

Early enterprise adopters reported faster cross-team alignment and fewer visual regressions after adopting the system, while teams with mature design systems saw immediate ROI from automated enforcement.
