Radix Vue is, as the name suggests, a port of the popular headless component library Radix Primitives (also referred to as Radix UI) from React to Vue. Radix Primitives has since its initial release in 2020 become a preferred library for creating custom components and design systems on top of its headless primitives, aiding in accessibility and component structure.
This library is a community-driven effort to port all of the components which Radix Primitives offer in React, which at the time of writing (August 2023) has been accomplished according to the repository's README.md.
