Both Fela and Tachyons are popular npm packages, but they serve different purposes and have different levels of popularity within their respective domains. Fela is a widely used styling library in the React ecosystem, while Tachyons is a popular CSS toolkit with a broader usage across various frameworks and projects.

Styling Approach

Fela is a CSS-in-JS library that follows a component-based approach. It allows you to write styles using JavaScript and generates atomic CSS classes at runtime. Tachyons, on the other hand, is a pre-defined set of utility classes that you can directly apply to your HTML elements. It focuses on functional CSS and encourages reusability and consistency throughout the project.


Fela is designed to be highly scalable, particularly in large-scale applications with complex styling requirements. It offers advanced features like dynamic styling, theming, and server-side rendering. Tachyons, on the other hand, is more suitable for smaller projects and rapid prototyping where simplicity and quick development are prioritized.


Fela provides a lot of flexibility with its plugin system and can be easily integrated with other tools and frameworks like Redux, React Router, and Next.js. It also offers a wide range of customization options. Tachyons, being a CSS toolkit, provides a set of predefined styles and utility classes that you can use out-of-the-box without much customization.

Learning Curve

Fela has a steeper learning curve compared to Tachyons due to its CSS-in-JS approach and the need to understand its APIs and concepts. Tachyons, on the other hand, has a shallow learning curve as it mainly involves applying predefined utility classes to style elements.


In terms of performance, both Fela and Tachyons have their strengths. Fela's atomic CSS generation at runtime allows it to achieve smaller bundle sizes and optimize rendering performance. Tachyons, on the other hand, benefits from its functional CSS approach, which promotes code reuse and reduces redundancy.

Community and Ecosystem

Fela has an active and supportive community within the React ecosystem. It has a variety of plugins and integrations available, and is often used alongside popular libraries like Redux. Tachyons has a broader community that extends beyond React, and it is well-established with a large number of contributors and resources.
