Hex UI blocksfor shadcn/ui.

Hex UI is an open-source collection of shadcn/ui section blocks made by Rion, a student in Japan who wanted solid starting points to customize rather than building every section from scratch. Its blocks cover announcement banners, heroes, calls to action, FAQs, footers, login forms, sidebars and social proof. Small touches set some apart: a footer whose type reacts to the pointer, logo grids with hover effects and marquees, and sidebars shaped for a notes app, a developer dashboard and an AI app.

Everything is built for React, Next.js and Tailwind CSS with Motion and lucide icons, and installs by copy and paste or with the shadcn CLI. AI coding assistants can reach the registry over MCP. All of the blocks are free, and the site also offers templates, such as a documentation site built on Fumadocs.
