@emotion/css and semantic-ui-react are both popular npm packages in the JavaScript ecosystem. However, semantic-ui-react is known for its widespread adoption and popularity in the React community.


@emotion/css is a CSS-in-JS library that provides a powerful and flexible way of writing and managing styles in React applications. It allows you to write styles using JavaScript and generates CSS at runtime. On the other hand, semantic-ui-react is a UI component library that offers a wide range of pre-designed, ready-to-use components for building user interfaces.

Developer Experience

@emotion/css provides a great developer experience with its intuitive API and support for CSS features like nesting, variables, and media queries. It also has excellent TypeScript support. semantic-ui-react, on the other hand, offers a rich set of well-designed React components with clear documentation and examples, making it easy to get started and build UIs quickly.


@emotion/css allows for highly customizable styling solutions as it provides full control over styles using JavaScript. Developers can dynamically generate styles based on props and have access to the full power of JavaScript. semantic-ui-react, on the other hand, provides a predefined set of components with a specific visual style. While it offers some customization options, it may not provide as much flexibility as @emotion/css.


@emotion/css can be integrated seamlessly into any React project, regardless of the UI library or framework being used. It works well with other CSS-in-JS solutions and allows for gradual adoption. semantic-ui-react is specifically designed for React and provides a comprehensive set of React components out of the box. It integrates smoothly with React projects and provides a consistent UI design language.


@emotion/css generates optimized CSS at runtime, which can result in a bit of additional overhead. However, it offers various optimizations and caching mechanisms to mitigate any performance impact. semantic-ui-react aims to provide performant UI components but may have a heavier initial bundle size due to including a larger set of pre-designed components.
