|---|---|---|---|
| What it is | Origin UI has been rebranded to coss ui and rebuilt on Base UI primitives — now the design system of Cal.com. 50+ components in three layers (Primitives, Particles, Atoms), copy-paste, explicitly built 'for developers and AI'. | 150+ animated components built with React, TypeScript, Tailwind and Motion, explicitly designed as the companion to shadcn/ui. Installs with the exact same CLI you already use. No Three.js dependency; components stay under ~5 kB tree-shaken. | Formerly Tailwind UI, from Tailwind Labs. 500+ copy-paste blocks across Marketing, Application UI and Ecommerce, plus every site template (Catalyst, Spotlight, Salient, Studio, Keynote) and the Catalyst React kit. Built for Tailwind v4.3. |

| Why builders pick it | Its historic strength was a very large set of input, select, checkbox and slider variants that shadcn ships only one flavor of — useful for subscribe forms, submission portals and contributor onboarding. | Best stack fit of the animated libraries. Animated beams for a table-of-contents, number tickers for circulation stats, shimmer on a subscribe CTA, marquee for a sponsor row — polish without changing anything structural or blowing the image budget. | The one component purchase I would actually make for a content site. Marketing pages, article headers, pricing and subscribe flows are exactly where default shadcn output looks unfinished, and this is first-party Tailwind markup that pastes straight in. One-time, lifetime, 30-day refund. |
| Watch out for | Not the library you may be remembering. Old Origin UI was 400+ Radix-flavored components; coss ui is a smaller, differently-architected Base UI library under new branding with some pieces still 'coming soon'. Verify the licence file on GitHub before commercial use. | not logged | React blocks use Headless UI, so you end up with two primitive libraries alongside shadcn's Radix/Base UI. Licence bars repackaging blocks into anything you resell. No update mechanism once pasted. |
