- The foundation most modern React kits — including shadcn — sit on.
Known limitations

- Not a drop-in component library for non-technical users.
- Some primitives have a learning curve.
Use it when
- Building a design system on correct behavior, then styling it yourself.
- Teams that want a11y baked into the primitive, not bolted on.
Skip it when
- You need a drop-in styled library for non-engineers.
- Styling everything from scratch is not in the budget.
- The primitive API learning curve would stall the sprint.
