Cult UI
82 free design-engineer components plus 10 paid full-stack AI starters
Cult UI is a shadcn-compatible registry of 82 MIT components aimed at design engineers, best known for its Apple-flavoured pieces — Dynamic Island, Dock, Family Button, Family Drawer, Expandable Screen — alongside texture cards, shader lens blur, dithered images, and pixel typography. A separate paid tier (Cult Pro at pro.cult-ui.com) sells 10 full-stack Next.js starters and a library of AI-agent interface patterns built on the Vercel AI SDK. For developers who want interface moments that feel hand-crafted rather than generic, and for teams who want a working AI product skeleton instead of loose components.
npx shadcn@latest add https://cult-ui.com/registry/styles/default/texture-card.jsonReach for Cult UI when the brief asks for a specific Apple-style interaction — Dynamic Island, a Dock, an expanding Family Button, a morphing drawer — because those are hard to rebuild and Cult ships them working. It layers cleanly on shadcn/ui since it reuses the same Radix primitives and the same default/new-york style folders. Two operational warnings: cult-ui.com sits behind a Vercel security checkpoint that returns 429 to non-browser clients, so a headless fetch of the docs or the registry JSON will fail and you should pull component source from the GitHub repo at apps/www/registry/default/ui instead; and the AI-agent patterns advertised on the homepage live in the paid Cult Pro tier, not in the MIT repo.
Why it is here. The reference implementation for Apple-grade interaction moments in React — six thousand stars because nobody else ships a credible Dynamic Island you can paste in.

Verified 2026-08-15. HTTP 429. https://github.com/nolly-studio/cult-ui (README), gh api repos/nolly-studio/cult-ui git tree (82 component files enumerated at apps/www/registry/default/ui plus the public registry JSON tree), https://pro.cult-ui.com/?ref=newcult.co (10 templates enumerated), https://www.newcult.co (307 redirect). cult-ui.com itself returned HTTP 429 'Vercel Security Checkpoint' on every attempt (/, /docs/components, /r/registry.json, /registry/styles/default/*.json), so the component list came from the repo, not the site. The install command above is the shadcn URL form derived from the repo's public/registry tree and was NOT confirmed live because of the block.
