BuilderIO/mitosis ? reverse-engineered prompt

I have an idea for a tool to make web development way more efficient, especially for teams that use multiple frameworks. I want to be able to write UI components—like buttons, cards, and forms—just one time using a simple, JSX-based syntax similar to React. Then, this tool should be able to compile that single source file into code that works everywhere: React, Vue, Angular, Qwik, Solid, Svelte, and even plain HTML.

This would be amazing for maintaining a consistent design system. A killer feature would be a direct integration with Figma. The idea is that you could design a component in Figma, and the tool would generate the base Mitosis code automatically. This would bridge the gap between design and engineering, letting us write a component once and use it natively across our entire tech stack.
