Show HN: Turn Markdown into React/Svelte/Vue UI at runtime, zero build step

This already exists in a mature state - https://mdxjs.com/

To me it has nothing to do with mdxjs.

Check it twice, what the submission implements is writing all the UI in markdown, not mixing markdown with React.

Perhaps I don't know mdxjs enough but that's my impression.

the reason I made it is that mdxjs (afaik) only works with a build step and locks the user into React, and you are still technically running code sent by the LLM, rather than a more secure static JSON like object.
