List variants from both sides
Each component's variants are listed separately for design and for code, since a component "existing" in both places does not mean every variant matches.

How it works
Find missing and extra variants
Variants present in design but missing from code (and vice versa) are identified precisely by name.
Score sync per component and overall
Each component gets a sync percentage based on matching variants, rolled up into an overall design-system sync score.
Frequently asked questions
Does this scan my actual codebase or Figma library?
No — you list the variants yourself from both sources. There is no automated scanning of a repository or design file.
What does a missing code variant usually mean?
Either the variant was designed but never implemented, or it exists in code under a different name — check both possibilities.
What does an extra code variant (not in design) mean?
Often a developer-added variant that was never formally designed — worth reviewing whether it should be documented or removed.
How is this different from DesignToken Sync?
DesignToken Sync compares individual values like colors and spacing; ComponentSync compares whole components and their variant sets.

MVPHub gives an instant structured comparison from data you already have. A consultancy audit can go deeper with actual codebase access but takes far longer and costs more.
