Utility-first framework engine for creating responsive powerful design systems

Maximum code reuse

Stop writing repeating styles. Rely on classes that define styles and behaviors once and for all. Utility classes expose a well-defined low-level API that you can use to compose more complex components.

Built to be customized

Yes! You are granted total freedom. Add your own utilities, customize class names, generate variant classes for breakpoints and pseudo-classes like hover in only one config file.

Just try responsive utilities.
Believe us, you'll like it.

Extensions Available

Yeap, utility classes are cool, but that doesn't mean that you won't have the opportunity to work with component classes too. Cumo offers it's own built-in ecosystem, tools like svg icon system, modules and objects.
