I've maintained Linaria for six years. Here's why I built something new

Runtime CSS-in-JS is winding down. styled-components has been in maintenance mode since early 2025, Server Components made the runtime model a structural dead end, and the default advice is "just use Tailwind." That advice is fine — for many teams it's correct. But if what you actually want is typed styles, tokens, and variants living next to your components, the zero-runtime branch of CSS-in-JS is where that lives, and I've spent the last six years in it: I maintain Linaria, and I'm the author of is what I built after all of that. This post is about why it exists.

What six years of issues taught me

Two problems came back over and over. Neither is fixable without breaking what Linaria is.

First: styled's component interpolation is priced wrong. ${Component} inside a template looks free. In practice it's the single most common way extra code leaks into build-time evaluation — and the most common reason static evaluation gives up and falls back to actually running your module. Every mitigation we shipped over the years — explicit HOC hints in plugin options, special heuristics for shaking interpolated components — is a patch on a pattern the API itself encourages.

Second: composition. Linaria hands you css and cx and wishes you luck. People have asked for style fragments for years, and I've pushed back every time: fragments would add chaos and complexity without addressing the actual need. In a real design system, variants, slots, and themes aren't advanced tricks — they're the ground floor. They belong in the styling library as first-class citizens, not as conventions every team reinvents on top of it.

Both fixes move the center of gravity of the API. Remove styled — or even demote it — and you've broken most of what's built on Linaria. So Linaria stays what it is, and stays maintained. The next thing had to be a new thing.

The trigger

My team started a component library from scratch, and Linaria turned out to be awkward in exactly the places a design system lives: tokens, variants, multipart components. We tried Griffel — itself a Linaria descendant, but through a fork that diverged around Linaria 3 and grew into a separate engine with no cross-compatibility with the wyw ecosystem: atomic classes didn't fit what we were building, and our custom processors would have meant maintaining two extraction pipelines side by side. At some point the conclusion was hard to avoid: we had more accumulated mileage with zero-runtime CSS-in-JS than anyone else, and we were spending it on working around our own tooling.

What Pigment taught me

MUI built Pigment CSS on wyw-in-js, then put it on hold. My takeaway wasn't about MUI — it was about speed. On a greenfield project, build time is a habit you form early. But when you migrate an existing codebase and the styling step suddenly costs 10× the rest of the build, that's a dealbreaker — I watched it happen. And 10× isn't the ceiling: I've seen style builds take tens of minutes and tens of gigabytes of RAM.

That experience pushed wyw-in-js toward static evaluation: prove what can be proven at build time, skip the evaluation sandbox entirely. The results so far are honestly mixed — but codebases that evaluate fully statically build several times faster. And the pattern that most reliably ruins static evaluation is the one from problem #1: styled.

dx-styles isn't perfect here either. A few of its processors still hit the JS fallback — creating a token contract does, in some shapes. That's a known, solvable problem, and the fix lands with wyw-in-js@3 and dx-styles@2.

What dx-styles is

import { createTheme, createTokenContract, css, recipe } from "dx-styles";



const tokens = createTokenContract(

  { color: { accent: null, accentFg: null } },

  { prefix: "app" },

);



const dark = createTheme(tokens, {

  color: { accent: "#7c8cff", accentFg: "#080a12" },

});



const button = recipe({

  base: { display: "inline-flex", borderRadius: "999px" },

  variants: {

    appearance: {

      primary: { backgroundColor: tokens.color.accent, color: tokens.color.accentFg },

      ghost: { backgroundColor: "transparent", color: tokens.color.accent },

    },

  },

  defaultVariants: { appearance: "primary" },

});



// <button className={button({ appearance: "ghost" })} />

At build time this becomes a static CSS file and plain class-name strings. Deterministic semantic classes you can snapshot and cache on. Recipes and slot recipes with typed variants. Token contracts instead of theme conventions. Opt-in compile-time RTL. No style runtime, no providers — and the same components work unchanged in React Server Components.

The part I didn't expect to be the best part

dx-styles is implemented as a set of wyw-in-js processors — and processors aren't limited to styles. In a commercial product I work on, the same build step that extracts CSS also statically executes parts of application logic and inlines the results, dropping dead weight from the bundle at compile time. It's a macro mechanism you get for free with your styling pipeline. Writing your own processor next to dx-styles is a supported extension point, not a hack — and every wyw-based library interoperates in the same build.

What I'm promising — and what I'm not

dx-styles is MIT and stays MIT. The issue tracker runs at zero open issues — and I owe you honesty about how. If you've followed Linaria closely, you may have noticed maintenance slowing down through 2024–2025: boring triage was quietly eating the entire energy budget. Since last October, agents have taken over that layer — turning reports into reproductions, bisecting regressions — and maintainer time goes into the actual engineering; the fixes I still mostly write by hand. That's the economics that makes zero-open-issues sustainable, and dx-styles gets it from day one.

wyw-in-js@3 has a written plan — the high-level roadmap is public () and the detailed plan goes further. The honest constraint is volume: it's a lot of work, and its pace will scale with how much the community cares about this direction. No dates.
