shadcn/ui: Radix primitives with Tailwind styling already applied, if you would rather not start from nothing
Overview
What Radix UI does
Radix UI provides unstyled, accessible React component primitives — dialogs, dropdowns, tooltips, comboboxes — that implement keyboard navigation, focus management and ARIA semantics without imposing any visual design. That split addresses the standing complaint about component libraries: teams want the accessibility work, which is genuinely hard and easy to get wrong, but not the visual opinions, which they will override anyway. Radix ships the behaviour and leaves appearance entirely open, which is why it underpins shadcn/ui and many in-house design systems.
What people use it for
- Design systems that need correct accessibility without inherited visual opinions
- Replacing hand-built dropdowns and dialogs that have accessibility bugs
- Teams with a designer whose output should not be constrained by a library’s theme

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Radix UI.
- You write all the styling, so time to a finished interface is much longer than with a styled library
- Composable part-based APIs are more verbose than a single component with props
- Covers primitives rather than complex widgets, so data grids and date pickers come from elsewhere

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Radix UI free?
Yes, open source under the MIT licence.
Why use unstyled components?
Because accessibility is the hard part and visual design is the part teams want to own. Radix gives the first and stays out of the second.
What is the relationship with shadcn/ui?
shadcn/ui is built on Radix primitives, adding Tailwind styling and copy-paste distribution on top.
