json-render
A generative UI framework for rendering structured specifications through a defined component catalog.
About json-render
Building AI-generated interfaces requires a way to turn model output into UI your application controls. json-render lets developers define a catalog of components and actions, generate JSON specifications, and render them with their own components.
Who it’s for
- Developers adding generated interfaces to AI applications
- Teams building interactive dashboards or UI inside a conversation
When to consider it
Consider json-render when your product can describe a useful interface with a bounded set of components. Start from the smallest catalog that serves the task and decide what each component is allowed to do.
Tradeoffs & limitations
- A constrained component catalog still needs application-level validation and safe action handling.
- Generated layouts need usability and accessibility review.
A useful first evaluation
Test unknown component types, missing properties and unusually long content. Keep data access and irreversible actions behind explicit server-side checks.

A Jev UI-composition experiment inside the json-render website that selects from predefined component and property options.
This covers the website’s Jev experiment, not the whole framework. Claims such as 3.21 s versus 880 ms were not independently verified.
