UIKit is a lightweight and modular front-end framework that provides a comprehensive set of customizable UI components to build responsive and mobile-first web interfaces. It offers pre-built CSS and JavaScript to handle typography, colors, icons, forms, navigation, and animations. UIKit is designed to be flexible and highly customizable, making it easy to create unique designs that match your brand and style. One of the primary benefits of using UIKit is the speed of development. By utilizing pre-built components, developers can quickly prototype and build out interfaces faster than building from scratch.

UIkit is a popular and widely used package for building responsive user interfaces, while Fela is a niche library focused on providing an efficient and scalable way to style React components. UIkit has a larger user base and community support compared to Fela.


UIkit is a comprehensive UI library that offers a wide range of pre-designed components, such as grids, forms, navigation, and more. It provides a complete solution for building user interfaces. Fela, on the other hand, is a more specialized library focused solely on styling components. It offers advanced styling capabilities like CSS-in-JS, theming, and dynamic styles.

Integration with React

Both UIkit and Fela can be used with React, but they have different integration approaches. UIkit provides a set of ready-to-use React components that can be easily imported and used in your project. Fela, on the other hand, is primarily a styling library and requires additional configuration to integrate it with React components. It provides hooks and higher-order components for styling React components.


UIkit offers a lot of flexibility due to its modular nature. You can choose to import only the components and features you need, which helps in reducing the bundle size. Fela, on the other hand, focuses on providing a flexible and efficient way to style components. It allows you to create reusable and composable styles using JavaScript objects or CSS syntax.

Developer Experience

UIkit aims to provide a developer-friendly experience by offering comprehensive documentation, examples, and an intuitive API. It is easy to get started and has good community support. Fela also has decent documentation, but it may have a steeper learning curve for developers who are new to CSS-in-JS concepts.


Fela is known for its performance optimizations. It implements efficient rendering techniques to minimize re-renders and optimize the overall performance of the styled components. UIkit, on the other hand, doesn't focus solely on performance but provides a well-rounded UI solution, which may have a slightly lower performance compared to Fela in terms of styling and rendering.
