Hi @bagusfikri, you can create a site template from scratch, export it from Webflow and then sell that on other marketplaces. You just cannot do that with templates or sites that are based on a free or paid template from the Webflow Template Marketplace.
Normally, template licenses are per site, and do not allow for resell. If you create your own site from scratch, without using a template, no problem !
