Could you build this?

Partial A basic UI component streaming renderer is doable with existing libraries, but creating a universal, cross-framework generative UI runtime with an intelligent gateway and repair layers requires specialized parser and compiler work.

What it would actually take: The core system requires an incremental AST tokenizer and streaming parser capable of rendering partially formed declarative JSON or DSL tokens across React, Vue, Svelte, and React Native. The gateway layer intercepts LLM streams, validates them against dynamic schemas, and applies real-time error-correction heuristics before components render. Developing this standard requires deep knowledge of compiler design, reactive frontend frameworks, and streaming network protocols.
