Mitosis review
An open-source JSX component compiler for generating code across frameworks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Mitosis is an open-source component compiler for developers who want to author UI components in a JSX-based format and generate code for multiple frameworks and platforms. Its documented targets include React, Vue, Angular, Svelte, Qwik, Solid, React Native, Lit, Stencil, Swift, Liquid, Preact, and Marko. That breadth makes it relevant to teams maintaining component work across different front-end ecosystems, while its focus remains component generation rather than general-purpose code transpilation.
The compiler uses a Mitosis JSON intermediate representation and configurable target generators, with framework-specific output options. Developers can use its CLI build and compile commands, or start a project with npm create. A playground supports experimenting with components. These features give teams several ways to work with the compiler, but they also mean Mitosis is best suited to workflows where developers can adopt its component format and configure or select the required outputs. Teams looking for a broader source-language conversion tool should consider a different category of product.
Mitosis connects with Figma through Builder.io’s Fusion workflow, which converts designs into Mitosis code. That makes it a fit for teams wanting a path from design work into generated components, though the workflow is specifically tied to Mitosis rather than serving as a general design-to-code solution. The project is open source, supports self-hosted use, and offers community and documentation support. Choose Mitosis when multi-framework component output and its JSON-based compiler workflow match your development process; it is a less natural choice if you need a hosted paid service, broader transpilation scope, or a different support model.
