JSS is a powerful and flexible JavaScript library for styling your applications. It provides a way to write CSS styles in JavaScript, allowing you to create dynamic and reusable stylesheets. With JSS, you can define styles as JavaScript objects or use CSS syntax with the help of a CSS-in-JS compiler.

Semantic UI React is a popular library that provides a set of reusable React components for building user interfaces. It is based on Semantic UI, a comprehensive CSS framework that offers a wide range of pre-designed UI elements and styles.

Semantic UI React is more popular and widely used than JSS, as it is a comprehensive UI library that provides pre-built components and a well-established community.


Semantic UI React focuses on providing a set of pre-designed and reusable UI components that follow the Semantic UI design language. It offers a wide range of components and styling options, making it ideal for building visually appealing and consistent user interfaces. On the other hand, JSS is a powerful JavaScript library for programmatically styling applications using JavaScript objects. It is more flexible and allows for greater customization and dynamic styling.


Semantic UI React is tightly integrated with React and provides a seamless experience when building React applications. It offers a declarative way to work with UI components and handles component state and event handling. JSS, on the other hand, is a general-purpose styling library and can be used with different frameworks, including React, Angular, and Vue.

Developer Experience

Semantic UI React provides a rich set of pre-designed components, which speeds up development and reduces the need for writing custom CSS. It also offers good documentation and community support. JSS, on the other hand, requires more customization and manual styling, which can make the development process slightly more complex. However, JSS provides a more programmatic approach to styling and allows for easier styling overrides and dynamic styles.


Semantic UI React provides a wide range of customizable themes and styling options, allowing developers to easily adjust the look and feel of their UI components. JSS, on the other hand, offers complete control over styling through JavaScript objects, making it highly customizable and suitable for complex styling requirements.


JSS generates and injects the styles directly into the HTML markup at runtime, which can lead to slightly slower initial rendering compared to pre-compiled CSS stylesheets used by Semantic UI React. However, once the styles are injected, JSS provides efficient and performant updates. Semantic UI React relies on pre-compiled CSS, resulting in faster initial rendering, but may require additional HTTP requests to load the CSS files.
