Foundation Sites is a front-end framework for developing responsive websites. Foundation offers various components such as responsive grids, buttons, navigation menus, forms, and typography styles that are easy to customize.

Foundation Sites is an excellent choice for building a custom web design system with modular components, ensuring consistency and saving time.

Foundation-sites is a popular front-end framework with a large user base, especially in the web development community. Fela, on the other hand, is a lesser-known library focused on styling in React applications. It is not as widely used as Foundation-sites but has a dedicated following within the React ecosystem.


Foundation-sites is a comprehensive UI framework that provides a wide range of ready-to-use components, layout systems, and utilities for building responsive websites. Fela, on the other hand, is solely focused on managing CSS styling in React applications and provides a more lightweight and flexible solution.


Foundation-sites offers a highly customizable framework with extensive theming options and configuration settings. It allows you to customize various aspects of the UI components and provides a rich set of built-in styles. Fela, on the other hand, gives you complete control over the styling of your components by using CSS-in-JS techniques. It allows for easy customization and dynamic styling based on React component props.

Integration with React

Both packages integrate well with React. Foundation-sites provides React-specific components and utilities for seamless integration, making it suitable for developers who want a comprehensive UI framework with built-in React support. Fela, being specifically designed for React, provides a more seamless integration and has a smaller learning curve for React developers.


Foundation-sites is a feature-rich framework with a larger codebase, which may impact the performance of your application. Fela, being a more lightweight solution, offers better performance when it comes to CSS styling in React applications. It follows a highly optimized rendering approach by dynamically generating and updating the necessary CSS styles based on the component tree.

Community Support and Documentation

Foundation-sites has a large and active community with extensive resources, documentation, and community-driven plugins. It has been around for a long time and has established itself as a popular framework. Fela, while not as popular, still has a dedicated community and provides comprehensive documentation, tutorials, and examples to help developers get started.
