Initium blocksfor shadcn/ui.

Initium, by Matt Wierzbicki, is a registry of shadcn/ui marketing blocks paired with tools that help AI coding agents build sites that look designed rather than generated. A Style editor sets colors, fonts, radius, buttons and forms from designer presets, then exports a DESIGN.md file or installs the style with the shadcn CLI. A Strategy builder works through audience, offer, proof and conversion goals and exports a STRATEGY.md, so the agent writes real copy and structure.

The blocks cover heroes, headers and navigation, features, galleries, contact, logos, stats, testimonials, calls to action and footers, with many variants of the big patterns, and they take on the chosen style. Agent skills tie it together for Cursor, Claude Code, Codex and others. Blocks are built on Base UI, with a Radix build for older setups. Style, Strategy and the first block in each category are free, and Pro is a one-time license.
