Cloner turns a well-configured Craft structure into a reusable starting point. Duplicate sections, entry types, groups, volumes, filesystems, transforms, and other project settings without rebuilding them by hand.
The second section with a familiar shape should not take as long as the first. Start from an existing configuration, choose a new name and handle, and let Cloner copy the settings — including substantial field layouts — ready for the details that actually need to differ.
Cloner does not create a parallel configuration system. The duplicate is a normal Craft configuration item, ready to adjust through the usual settings screens; it handles the repetitive setup and then gets out of the way.
Available for Craft 4 and 5. Get it from the plugin store.
