Radix UI and Tailwind UI both answer the same question: where do your components come from? Unstyled, accessible React primitives that handle focus, keyboard and ARIA while you supply every pixel of design. Paid marketing and application page sections from the Tailwind team, sold as markup you paste and adapt. The real split is ownership: Radix UI runs inside your project and leaves the operational work with you, while Tailwind UI runs the hard parts as a service and takes a dependency in exchange.

Neither is better in the abstract. The real split is ownership: Radix UI runs inside your project and leaves the operational work with you, while Tailwind UI runs the hard parts as a service and takes a dependency in exchange. Pick the one whose downside you can absorb, because both upsides are real.
You style everything yourself, which is real work before anything looks finished. Only primitives, so higher-level pieces like tables or charts are missing.
Costs money up front before you know whether the designs suit your product. Markup is a starting point, so responsive tweaks are still your work.
Usually, at a cost that grows with how much of your product leans on the ui kit layer. Keep the integration behind a thin module of your own and the migration stays a weekend rather than a quarter.
