Shopify is a platform that allows users to create their own online stores. Etsy is an online marketplace that specializes in handmade and vintage items. Shopify offers a free integration with Etsy, which allows Shopify users to list their products on Etsy. This integration is beneficial for Shopify users who want to reach a wider audience, as Etsy has a large user base. However, there are some downsides to using this integration, such as the fact that Shopify takes a percentage of each sale made on Etsy.
