3 min read
Linear finished moving its React apps from styled-components to Meta's StyleX in early August 2026, after roughly five months and more than 1,000 pull requests. Engineer Kenneth Skovhus built a deterministic codemod spanning about 100,000 lines. Linear reports 20 to 35 percent less main-thread work on view-heavy pages and about 30 percent faster navigation on a mid-tier machine.
