How these alternatives were chosen
Tools 21st names as alternatives that this directory also publishes, followed by others in Component. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
21st also lists Aceternity UI, Figma component libraries, Vercel's v0 as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
