Editorial take
Why it stands out
Radix is easiest to justify when the team knows it wants design-system control and is willing to pay for that in implementation time.

Tool profile
Open-source React primitives and themes for building accessible, design-system-friendly interfaces without shipping a fully opinionated visual layer.
Custom design systems built on accessible UI primitives
Radix UI is one of the most important frontend infrastructure choices to list because it represents a different way of building UI than a traditional component kit. Instead of forcing a finished visual system onto the product, Radix gives teams accessible primitives and themes they can shape into their own design language. That makes it especially relevant for design-system teams and product teams that care about control more than fast default styling.
The economics are refreshingly simple. Radix Primitives and Radix Themes are open source under the MIT License, with no required subscription for the core libraries. The real cost is engineering time: composing primitives, adding styling conventions, and owning more of the design-system layer yourself. Compared with Material UI or Ant Design, Radix trades faster out-of-the-box screens for more long-term control.

Ant Design
Free planEnterprise and back-office React applications
Enterprise-class React UI design system and component library with a free MIT-licensed core and a strong opinionated visual language.
Choose Ant Design when speed and enterprise-style consistency matter more than design neutrality.
Pricing snapshot
Radix Primitives and Radix Themes are open source under the MIT License and free to use. There is no published commercial subscription for the core libraries themselves, so the real cost is the engineering work around styling, composition, and design-system maintenance.
