Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A JavaScript library for writing CSS styles inside your code, mainly for React apps.
Open source · MIT
A CSS-in-JS library that extracts styles to plain CSS files at build time, so no styling code runs in the brow
The short answer
Choose Emotion if you need…
- React developers who want styles colocated with components
- Teams that want to combine and reuse style objects in JavaScript
- Developers who want source maps and labelled class names while debugging
- Projects that want to optionally add a Babel plugin for extra optimizations
Choose Linaria if you need…
- React or other JavaScript teams who want CSS-in-JS without a runtime styling cost
- Projects that already use a supported bundler and can add a build-time plugin
- Developers who like CSS syntax with nesting and want JavaScript variables inside styles
- Teams that want source maps and stylelint support for styles written in JS

What each one is
Emotion
Emotion is a CSS-in-JS library: you write styles as strings or JavaScript objects inside your components instead of in separate stylesheet files. It is described as offering predictable style composition to avoid CSS specificity problems, plus source maps and labels for debugging. It is aimed at developers building web interfaces, and the README mentions React usage.
Linaria
Linaria lets you write CSS inside JavaScript files, such as with a css tag or a styled helper for React. During the build step, those styles are pulled out into ordinary CSS files, so the browser does not need extra JavaScript to apply them. It is built on the wyw-in-js build tooling and works with bundlers like webpack, Vite, Rollup, and esbuild.
Best for
Emotion
- React developers who want styles colocated with components
- Teams that want to combine and reuse style objects in JavaScript
- Developers who want source maps and labelled class names while debugging
- Projects that want to optionally add a Babel plugin for extra optimizations
Linaria
- React or other JavaScript teams who want CSS-in-JS without a runtime styling cost
- Projects that already use a supported bundler and can add a build-time plugin
- Developers who like CSS syntax with nesting and want JavaScript variables inside styles
- Teams that want source maps and stylelint support for styles written in JS
Strengths
Emotion
- The README describes predictable composition that helps avoid CSS specificity issues
- Source maps and labels are offered for developer experience
- The package is MIT licensed and has a large community with 18k+ GitHub stars
Linaria
- Styles are extracted to CSS files at build time, so there is no styling runtime in the browser according to the README
- Supports nesting, sourcemaps, and optional preprocessors such as Sass or PostCSS
- Has a documented setup for common bundlers and an MIT license
Not ideal for
Emotion
- Designers or non-programmers, since it requires writing JavaScript code to style pages
- Projects that prefer plain CSS or CSS modules and do not want a runtime styling library
- Teams needing a framework-agnostic setup beyond what the README covers, since the README focuses on React examples
Linaria
- Projects that need dynamic styles inside the css tag, since the README says those are not supported there
- Apps that must support IE11, because dynamic styled components rely on CSS custom properties
- Teams whose build setup cannot run Node.js 22.12.0 or newer, which Linaria 8 requires
- Codebases with shared style helper modules that have side effects, since the README says modules used in CSS rules cannot have side effects
Trade-offs
Emotion
- It is a runtime styling library, so styles are computed in JavaScript, which the README does not quantify beyond claiming good performance with caching
- The README is truncated and most detail lives in the external docs site
- The Babel plugin is optional, so getting the most out of it means extra setup
Linaria
- Build-time evaluation can cause slow builds or unexpected behavior if modules have side effects, per the Stability and Trade-offs sections
- Some features are limited, such as no IE11 support for dynamic styled components and no dynamic values in the css tag
- Setup is split across the wyw-in-js.dev site, so configuration requires reading external docs
