Shadcn UI Blocks blocksfor shadcn/ui.

Shadcn UI Blocks is a catalog of shadcn/ui blocks written as plain React and Tailwind CSS on shadcn primitives, with each block bundling the primitives and sibling blocks it uses so it installs in one step. The catalog is sorted into collections across three tiers: Premium is Modern SaaS, built one block at a time in a single style, Standard covers marketing, ecommerce, application and portfolio blocks made at scale, and Free is the earlier work, open to everyone.

The blocks listed here come from the free collections, such as heroes with forms, testimonials, promo sections and newsletter footers. Around the blocks sit an in-app page Designer, Open Graph image templates, a hosted MCP server and a browsable catalog of community registries. Free collections install without a key, Pro and Team plans unlock the rest with an API key, and full-site templates are sold separately as one-time purchases.
