Modulz
Visual code editor for building production-ready design systems without writing code
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.
Pros & Cons
Pros
- Bridged the design-to-code gap by generating production-ready components from visual designs
- Design linting automated quality checks for accessibility, contrast, and performance
- Built-in design system documentation with auto-generated styleguides
- Open-source contributions including the widely-adopted Radix UI component library
- Generated accessible, standards-compliant code by default
Cons
- Product was discontinued after WorkOS acquisition in June 2022 and is no longer available
- Never reached full product-market fit before being sunset
- Limited ecosystem compared to established tools like Figma or Sketch
- Steep learning curve for designers unfamiliar with component-based design thinking
- No active development or support since mid-2022
