I'm building Sanityblocks (premium) and Schema UI (open source) - Sanity and Next.js page builder templates with pre-built blocks, built with shadcn/ui components. Schema UI is one of the first templates designed to be AI-native, fully compatible with Content Agent and MCP out of the box. I used Content Agent to build both the Sanityblocks and Schema UI homepages itself, showing what's possible when templates are built with AI workflows in mind.
