Why the models rank shadcn/ui — on best react component library for ui
“The de facto default for new React apps in 2026 — copy-in components you own outright, built on accessible headless primitives (Radix/Base UI) + Tailwind, with a huge registry ecosystem and first-class support in AI codegen tools (v0, Cursor, Claude Code), so it fits how teams actually ship UI now; assumes you're on Tailwind and comfortable owning component code”
