Several eCommerce platforms like Shopify, Wix, WooCommerce, BigCommerce, and more exist. Each of these comes with a unique set of features. While Shopify and Wix are the most popular, you might want to consider which platform best suits your needs over what is most popular. For instance, for a solopreneur, Squarespace may be the better option, but for someone looking to expand their business, Wix might be the better choice.
