vercel-labs/json-render
json-render is a Generative UI framework from Vercel Labs that lets AI build dynamic UIs from natural-language prompts while staying constrained to developer-defined component catalogs and Zod-validated JSON schemas. It supports React, Vue, Svelte, Solid, React Native, Remotion, React-PDF, React-Email, Ink, and Next.js, includes 36 pre-built shadcn/ui components, and streams output progressively as models respond. Setup involves three steps: defining a catalog of components/actions with schemas, implementing those components via `defineRegistry`, and rendering AI-generated specs with a `Renderer` component.

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
