## What it is
Mitosis is an open-source compiler that transforms JSX components written once into native components for frameworks like React, Vue, Angular, Svelte, Solid, Qwik, and more. It enables maintaining a single source of truth for design systems and cross-framework SDKs, with Figma-to-code sync support.

## Use cases
- write UI components once and compile them to React, Vue, Svelte, Angular, and other frameworks
- maintain a consistent design system across multiple frontend frameworks
- build cross-framework SDKs from a single codebase
- convert Figma designs into multi-framework component code
- avoid web component limitations by compiling to native framework code
- publish component libraries to npm targeting several frameworks

## When to choose
- you maintain a component library or design system that must support multiple frontend frameworks
- you want one source of truth instead of duplicating components per framework
- web components fall short for your SSR or framework-integration needs

## When to avoid
- you target only a single framework and can write components natively
- your components rely on framework-specific features Mitosis cannot express
- you need a full application framework rather than a component compiler
