Help: How to discover an ecommerce UI library

Hello,

I am learning about web development, and setting up an online store for my sister and mother in wordpress. I found an ecommerce store on the internet, they saída de maternidade in Brazil, and I would like to know what UI technologies and libraries they use for this store. Is there an extension for this?

Thanks.

WhatRuns seems to be a popular one, you can get the extension here and the official website here.

You could also builtwith.com, although I can’t find an extension for it (here’s the website).

I take that back, here’s the extension for BuiltWith.
