## What it is
json-render is a Generative UI framework that lets AI generate dynamic, personalized interfaces from natural language prompts, constrained to a developer-defined catalog of typed components and actions. It renders JSON specs natively across React, Vue, Svelte, Solid, React Native, and other targets with type safety and no arbitrary code execution.

## Use cases
- generate UI from AI prompts
- build guardrailed generative UI dashboards
- stream AI-generated interfaces progressively
- render AI output as native components instead of raw HTML
- create personalized dashboards from natural language
- let LLMs compose UIs from a predefined component catalog
- build AI chat apps that render rich structured responses
- generate PDFs, emails, or video from AI prompts

## When to choose
- you want AI to generate interfaces but with strict guardrails and predictable output
- you need the same AI-generated UI to render across web, mobile, and other targets
- you want type-safe, schema-validated AI output with no arbitrary code execution
- you're building LLM apps that need rich, dynamic UIs beyond plain text responses

## When to avoid
- your UI is static and AI only needs to fill in data
- you need fully free-form AI-generated code or arbitrary layouts outside your component catalog
- your stack isn't among the supported frameworks (React, Vue, Svelte, Solid, React Native)
