Shark UI is an MIT-licensed component library that keeps the shadcn/ui workflow — CLI add, source lands in your repo, you own it — but swaps Radix for Ark UI primitives and styles everything with Tailwind CSS v4 plus tailwind-variants. It ships 86 documented components, 9 utility helpers, a hooks page, form recipes for React Hook Form / TanStack Form / Formisch, RTL support, and 13 neutral scales crossed with 16 accent colours as copy-paste themes. Built by Vinicius Vicentini; first beta January 2026, release candidate March 2026, still shipping as of August 2026.

Install

pnpm dlx shadcn@latest add @shark/ui

For an agent

Reach for this instead of stock shadcn/ui when the project needs components Radix simply does not have — signature pad, image cropper, QR code, colour picker, circular slider, tour, floating panel — because Ark UI covers them and the install path is still `shadcn add`. It is genuinely the most agent-friendly entry in this batch: a valid llms.txt at /llms.txt, registry items served at /r/<name>.json against the shadcn registry-item schema, and a first-party Agent Skill via `pnpm dlx skills add sharkui-inc/shark-ui`. Watch two things: it requires Tailwind CSS v4 (v3 projects will not work), and although the marketing copy names Solid, Vue and Svelte, every installation guide on the site is React-only, so treat non-React support as unverified.

Why it is here. It is the cleanest proof that the shadcn distribution model is now a neutral transport layer rather than a Radix-only club, and it closes real component gaps that shadcn/ui leaves open. For an index dominated by registries, this is a high-quality, well-documented one that an agent can consume end to end without a browser.
