| API | The API documentation describes displaying a fiddle from a POST request without saving it on JSFiddle. | The API is available for applications to try, but access is limited and service is not guaranteed; business users are asked to contact Paiza with expected usage. |
| Embedding | Fiddles can be embedded on other pages using an iframe or script, with selectable tabs, theme, and accent color. | Users can generate an HTML embed snippet so code can run from a blog post. |
| Free plan | Yes | Yes |
