Tailwind v4 Oxide engine made builds 100x faster, shadcn/ui rewrote the definition of "component library," Radix UI became the accessibility-primitive standard, Mantine 7 and Chakra v3 became the two poles of full-stack React UI, and Open Props · UnoCSS · Panda CSS forked the three roads of tokens, atomic, and build-time CSS-in-JS. This article maps the entire 2026 stack — alongside native CSS weapons like container queries, View Transitions, oklch, and color-mix() — into one selection matrix across 17+ stacks.

Tailwind v4 Oxide 엔진이 빌드를 100배 빠르게 만들었고, shadcn/ui가 컴포넌트 라이브러리의 정의를 다시 썼고, Radix UI가 접근성 프리미티브의 표준이 되었고, Mantine 7 · Chakra v3가 "풀스택 React UI"의 두 축이 되었고, Open Props · UnoCSS · Panda CSS가 토큰 · 아토믹 · 빌드타임 CSS-in-JS의 세 길을 갈랐다. 이 글은 컨테이너 쿼리 · View Transitions · oklch · color-mix() 같은 2026 네이티브 CSS의 새 무기들과 함께, 17개 스택의 선택 매트릭스를 한 호흡으로 정리한다.
