Yet at the same time, the developer experience of scoped, typed, dead-code-eliminated styling is so good that CSS-in-JS libraries still power the majority of production React apps. The tension is simple: runtime CSS-in-JS gives you the best DX but taxes your users&rsquo; CPUs; zero-runtime approaches give performance back but cost you features. In 2026, the three libraries that define this spectrum are styled-components (41,125 stars), Emotion (18,017 stars), and Linaria (12,347 stars) — and the right choice depends almost entirely on one question: <strong>can your team afford the runtime?</strong></p>
