Spectrum UI blocksfor shadcn/ui.

Spectrum UI is an open-source library of animated React components and blocks by Arihant Jain, released under the Apache 2.0 license and unrelated to Adobe's Spectrum design system. It's built with Next.js, Tailwind CSS, Motion and shadcn/ui on Radix primitives, with a focus on SaaS dashboards, AI apps and admin panels. The components lean on small, satisfying interactions: hold to confirm, swipe to delete, an undo pill, a scratch card, a metal prompt bar, number tickers and 3D tilt cards.

The blocks listed here are product UI states and tables, such as empty states for search, quota, trash, offline and integrations, a loading state, a voice input, and orders, files and audit log tables. Everything installs with the shadcn CLI under @spectrumui, and its MCP server lets Cursor or Claude add components on request. The project is backed by the Vercel OSS program.
