The Generative UI framework

How builders describe it

Generative UI framework with an experimental Jev composer that selects components and layout from application-supplied candidates through Vercel AI Gateway, rendering catalog-constrained JSON specs.
New experiment: json-render + Jev. The future of generative UI is instant — your components, your actions, your design system, rendered in milliseconds. Try it: experimental_composeSpec, experimental_createEvaluator. — @ctatedev (2.5K likes)

The decision Jev makes

Pick the next musical direction, visual option or UI component.

Where it fits

Using repeated small choices to steer something creative: music, pixel art, layouts and interfaces that assemble themselves from a fixed vocabulary. All 69 creative & generative ui projects →
