Export downloads your project’s code as a ZIP, so you can run it, host it or keep building it anywhere. Code export needs a paid plan. On Free, Export code is disabled and says Code export requires a paid plan — upgrade to export your app.

​
Download the ZIP

  1. Switch the canvas header to Code.
  2. Click Export code, then Export as React App.
  3. With several prototypes, pick the one the app should open on.
  4. Polymet says Your file is being downloaded now. Please check your downloads folder. The ZIP is named after the prototype.
Export waits for a running generation to finish.

​
What is in the ZIP

  • Every file in the project: pages, components, prototypes, styles and config.
  • The project’s git history, so every version comes with it.
  • The prototype you picked as the app’s starting screen. With several prototypes, the others are listed as comments at the top of src/App.tsx, so you can switch.
  • A linked design system’s components, which live inside the project’s own files.

​
Other ways to take your code out

Both of these also need a paid plan:
  • Edit code — change files by hand inside Polymet
  • Plans — which plans include code export
