vs CVA (Class Variance Authority)
CVA is an excellent, lightweight variant generator. Tailwind Variants started as an extension of that idea.
Choose CVA when you want the smallest possible variant helper and are fine wiring tailwind-merge yourself.
Choose Tailwind Variants when you want slots, built-in merge, compound slots, and a design-system-oriented API — especially for component libraries like HeroUI.
