Radix UI vs Base UI Package Sync

packages/radix-ui (fumadocs-ui) and packages/base-ui (@fumadocs/base-ui) are two variants of Fumadocs UI. They share the same layout structure, components, and public API; only the underlying primitives differ. When changing one package, consider the other.

Package identity

What to keep in sync

• Layouts: layouts/docs, layouts/flux, layouts/home, layouts/notebook, layouts/shared — structure and props should match; only primitive usage differs.
• Components: Same public API and behavior for components under components/ (e.g. toc, steps, sidebar/page-tree, dialog/search behavior). UI primitives in components/ui/ differ by design.
• Provider: provider/base.tsx — same props; only DirectionProvider and search/dialog primitives differ.
• Contexts, utils, i18n, mdx, og: Should stay identical or nearly identical.
• package.json: Same exports shape and version; dependencies differ (Radix vs Base UI).
