In Depth
shadcn/ui
shadcn/ui is not a component library you install. It is a CLI that copies accessible, well-styled React components into your codebase. Components are built on Radix Primitives for behavior and Tailwind for styling. Because the source lives in your repo, you can change anything. shadcn became the default component layer for Next.js apps in 2024-2025 and now ships first-class registry support so teams can publish their own component sets. The trade-off versus a packaged library is that you maintain the components.
Radix UI
Radix UI is a set of unstyled accessible React primitives from the WorkOS team. It covers the components that are painful to build correctly: dialogs, popovers, dropdown menus, tooltips, sliders, accordions. You bring the styling, Radix handles focus management, keyboard interaction, ARIA attributes, and edge cases like portal rendering and scroll locking. shadcn/ui is built on Radix, which is why so many production Next.js apps depend on it transitively.
The Verdict
Both shadcn/ui and Radix UI are strong tools in the infrastructure space. The right choice depends on your workflow. Read the full review of each tool for a deeper dive, or watch the video walkthroughs to see them in action.
