TL;DR
Shadcn/UI has changed its default UI framework from Radix to Base UI. This update affects developers relying on the library for component styling and functionality. The change is confirmed and is part of ongoing updates to improve usability.
Shadcn/UI has officially shifted its default UI framework from Radix to Base UI, a move confirmed by the project’s maintainers. This change impacts developers who rely on the library for building user interfaces, signaling a strategic shift in the library’s design approach. The update is part of ongoing efforts to streamline component development and improve usability.
The change was announced on the official Shadcn/UI repository and community channels in March 2024. Previously, Radix was the default underlying framework for components, providing accessibility and interaction features. Now, Base UI will serve as the default, offering a different set of design principles and component behaviors.
According to the maintainers, this transition aims to simplify the developer experience and align with the evolving ecosystem. The switch is confirmed by the project’s latest release notes and documentation updates. Developers who have integrated Radix-specific features will need to adapt their codebases accordingly, but no immediate breaking changes have been reported.
Implications for Developers Using Shadcn/UI
This change is significant because it alters the foundational UI framework that developers rely on when building components with Shadcn/UI. Moving from Radix to Base UI could influence how components behave, their accessibility features, and overall design consistency. For many, this shift may require updates to existing projects, but it also signals a potential future direction for the library, emphasizing simplicity and alignment with Base UI’s design system.
For the broader developer community, this move reflects ongoing trends toward streamlining UI libraries and reducing dependencies on multiple frameworks. It may influence similar projects to reconsider their default configurations and underlying technologies.

Background on Shadcn/UI and Its Framework Choices
Shadcn/UI is a popular open-source component library that enables developers to rapidly build styled user interfaces. Initially, the project integrated Radix, a library known for accessibility and interaction primitives, as its default backend for component behavior. Radix’s modular approach provided flexibility but also added complexity for some users.
Over time, the maintainers have explored alternative frameworks to improve developer experience and simplify integration. Base UI, a design system and component library focused on minimalism and consistency, has gained traction within the community. The recent update to set Base UI as the default reflects this evolving landscape and the project’s strategic direction.
This shift follows several months of community feedback and internal testing, culminating in the official change announced in March 2024.
“Our goal is to provide a more streamlined, accessible, and consistent experience for developers, which is why we’ve transitioned the default framework from Radix to Base UI.”
