Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
Write UI components once in a JSX-like syntax and compile them to many frameworks.
Open source · MIT
A workshop for building, viewing, and testing UI components one at a time, outside the full app.
The short answer
Choose Mitosis if you need…
- Teams maintaining the same UI components across more than one framework
- Library authors who want to publish components for several frameworks
- Developers already comfortable with JSX and TypeScript
- Projects that want to experiment with framework-agnostic component code
Choose Storybook if you need…
- Frontend teams building a shared component library or design system
- Developers who want to develop a UI component without running the whole app
- Teams that want living documentation of their components
- Projects using one of the supported renderers such as React, Vue 3, or Angular

What each one is
Mitosis
Mitosis is a TypeScript-based compiler that lets you write component code once in a JSX-style syntax and output it for several frameworks, such as React, Vue, Qwik, Solid, Angular, and Svelte. Teams use it to avoid maintaining the same component separately for each framework. The README provided here is truncated, so details beyond the project description and topics are limited.
Storybook
Storybook is a frontend workshop where you build and view UI components and pages in isolation, away from the rest of your application. Teams use it for UI development, testing, and documentation. It supports many frameworks, including React, Vue 3, Angular, Svelte, and web components, and it can be extended with addons.
Best for
Mitosis
- Teams maintaining the same UI components across more than one framework
- Library authors who want to publish components for several frameworks
- Developers already comfortable with JSX and TypeScript
- Projects that want to experiment with framework-agnostic component code
Storybook
- Frontend teams building a shared component library or design system
- Developers who want to develop a UI component without running the whole app
- Teams that want living documentation of their components
- Projects using one of the supported renderers such as React, Vue 3, or Angular
Strengths
Mitosis
- Single source for components across multiple frameworks
- Open source under the MIT license
- Built in TypeScript with an active project history (about 14,000 GitHub stars)
Storybook
- Widely used, with 91k+ GitHub stars and a large community
- Supports many frameworks and renderers listed in the README
- MIT licensed and open source
Not ideal for
Mitosis
- Projects using a single framework with no plans to change, since the compile step adds overhead without a clear benefit
- Beginners new to web development, who will do better learning one framework first
- Teams needing full support for every framework feature, because compiled output may not match hand-written code exactly
Storybook
- Projects with no UI components to isolate, since the tool is built around components and pages
- Non-frontend developers, because it is a tool for building user interfaces
- Anyone needing a no-setup tool, since the README points to docs and framework-specific setup
Trade-offs
Mitosis
- README was truncated, so the full feature list and limits could not be verified here
- Output quality and framework feature coverage may vary by target
- Adds a build step and a new syntax to learn on top of your framework
Storybook
- Setup and configuration depend on your framework and addons, which the README only summarizes
- The README is truncated, so detailed install steps must be taken from the official docs
