About Modulz
Modulz was a visual code editor that empowered teams to design, develop, document, and deploy design systems without writing code. Unlike traditional design tools optimized for illustration, Modulz focused on designing with real, production-ready components, bridging the gap between design and code. The company was acquired by WorkOS in June 2022, and the team behind it also created the popular Radix UI component library.
