Create shopify type of Application

i'm currently working on multitenant application that enable user to create a personalize website after selecting a template, please is there any gem or method to achieve this?? Shopify type of Application. Thanks

I would recommend checking out Liquid templates (which was made by Shopify!) for customizing the templates. http://liquidmarkup.org/

They've also got a bunch of other very helpful gems that they've open sourced which can really help. Take a look at their Github profile for those. https://github.com/shopify
