Host themes without an e-commerce platform

I want to start selling themes on the platform. But I don’t have an e-commerce platform account to install my theme, do I want to create a preview, how to do it?
Here’s an example:

I don’t have the store preview and I understand that it makes selling difficult. I would not like to pay for the e-commerce platform, do someone have any alternative to host?


for live preview of the template/theme demo you must have a hosting server where you will install and setup necessary web tools (as like joomla/wordpress, joomla template/wp theme and other necessary modules/plugins) to display the demo preview. Inshort for live preview you will need your own hosting server.


I understand, however for private platforms like shopify, x-cart, does anyone have any solutions?
