Radium has been around for longer and has gained popularity in the React community. It has a sizable user base and is widely used in production applications. WindiCSS is a relatively newer library but has been rapidly growing in popularity, especially within the Vue.js ecosystem.


Radium is a tool for managing inline styles in React components. It provides advanced features like automatic vendor prefixing and media queries. WindiCSS, on the other hand, is a utility-first CSS framework aimed at providing a high-performance and on-demand utility generation. It focuses on writing HTML first and then automatically generates CSS classes for the styles used in the HTML, which can help reduce the overall CSS bundle size.


Radium can be seamlessly integrated into existing React projects without any major modifications. It enhances the React component model and provides additional style management abilities. WindiCSS, on the other hand, can be used with any JavaScript framework and does not specifically target React. It can be easily integrated into projects without any strict dependencies on the framework being used.

Developer Experience

Radium provides a simple and intuitive API for managing inline styles in React components. It allows for dynamic style calculations and makes it easy to work with pseudo-classes, media queries, and keyframes. WindiCSS, on the other hand, offers a utility-first approach with a focus on simplicity and ease of use. It provides a streamlined development experience by automatically generating utility classes based on the used styles.


Radium can introduce some performance overhead when dealing with a large number of components due to the inline style transformations it performs. The impact on performance can be mitigated by using certain optimizations provided by Radium. WindiCSS, being a utility-first CSS framework, focuses on generating optimized and minimal CSS by removing unused styles. This can lead to smaller CSS bundle sizes and potentially better performance.

Community and Ecosystem

Radium has a strong community support and has been widely adopted in the React ecosystem. It has been around for a long time and has a mature ecosystem of plugins and integrations. WindiCSS is gaining popularity and has an active and growing community, particularly in the Vue.js ecosystem. It may have a smaller plugin ecosystem compared to Radium, but it offers excellent integration with various build tools and frameworks.
