Migrate Radix UI to Base UI With Claude Code
Migrate one component or a full React project from Radix UI to Base UI while preserving behavior, styling contracts and accessibility checks.
Treat primitive migration as a behavior and API translation, not a package-name replacement.
Radix UI and Base UI solve similar problems with different component APIs and composition details. The migration should inventory every primitive, wrapper and styling dependency before changing imports.
Who this guide is for
React and shadcn/ui projects moving individual primitives or a full component system from Radix UI to Base UI.
- Find direct and wrapped Radix dependencies across the project.
- Translate behavior, state and styling contracts component by component.
- Verify keyboard, focus and screen-reader behavior after each migration batch.
Which skills fit this job?
Start with the narrowest option that covers the full output. The package is useful when the workflow regularly crosses several specialisms.

Primary migration guide
Migrate Radix to Base UI Agent Skill
Handles individual components and full-project moves from Radix primitives to Base UI.
Claude Code or a compatible coding agent with shell access and the named project tools.

Contract preservation
Design System Agent Skill
Keeps tokens, component specifications and reusable styling rules explicit during the migration.

Repository-wide orchestration
Frontend Agent Skill
Coordinates implementation, responsiveness, accessibility and evidence-based visual QA across an existing codebase.

A practical workflow
Inventory every primitive
Search imports, wrappers, shared components, tests and CSS selectors that depend on Radix behavior.
Migrate by interaction family
Move one coherent component group, adapt state and slots, then repair styling and types before expanding scope.
Verify behavior and visuals
Run tests and inspect keyboard navigation, focus management, portals, positioning and responsive layouts.
Where this approach stops
Keep this boundary visible
Do not remove the Radix packages until the project has no direct, wrapped or transitive usage that the application still relies on.
Questions before you choose
Can the skill migrate only one component?
Yes. It supports focused requests such as migrating an accordion as well as planned whole-project work.
Will the rendered design stay identical?
It can remain close, but API and behavior differences may require markup or CSS changes that must be checked visually.
