I've been working with and teaching others to work with WordPress since 2009. All my sites and my clients' sites use Elementor.

It would not be ideal for UI Replicator [or even Cyotek WebCopy, which is what I use now to replicate sites] to integrate directly with WordPress.

Every site you replicate will have different "things" going on in the backend. I'm thinking about Wix, Shopify, SquareSpace and all those other "site tonight" options that you might end up finding when you pick sites to replicate.

However, having the HTML, CSS, and JavaScript to refer to is ideal when working with page builders like Elementor, Divi, Oxygen, Bricks and so on, because they all have the functionality to allow you to RECREATE any site you replicate. Even replicating a WordPress site will allow you to see what plugins are used on the site you replicate.
