Major shadcn Registry Libraries
June 2025 blog roundup naming eight shadcn registry libraries in ~900 words
A short article by Ryota Murakami of Laststance.io that walks through the shadcn/ui registry ecosystem as it stood in mid-2025. It names Magic UI (150+ components), Aceternity UI, Shadcn Blocks (631 blocks at the time), Origin UI, Cult UI, Kokonut UI (100+ components), and Neobrutalism Components, plus passing mentions of Shadcn Form Builder, StyleGlide, and Kibo UI. Each gets one or two sentences on design style and use case; there is no comparison table, no benchmarks, and no per-component detail.
Do not use this as an install reference. The command it prints — npx shadcn-ui@latest add alert --registry https://registry.example.com/components.json — is the deprecated package name and a flag the current CLI does not use; the correct form is npx shadcn add @<registry>/<component>. Its counts are frozen at June 2025 (Shadcn Blocks is quoted at 631 blocks and now advertises 1,429). Read it only as a narrative orientation to the ecosystem, then get the real list from https://ui.shadcn.com/r/registries.json.
Why it is here. A readable snapshot of which registries mattered before the official directory existed — useful for context, superseded for anything operational.
