I don't understand why someone would use AI to build an e-commerce site.
For someone that doesn't know what they're doing, use something prebuilt and cloud-hosted like Shopify or Square. Even some major brands use it. The largest electronics store in Australia (JB HiFi, similar to Best Buy in the USA) uses Shopify Plus. I think Staples in the USA/Canada uses Shopify too.
For someone that does know what they're doing, they wouldn't have left it open for other people to edit it. AI still needs fundamental understanding of how e-commerce sites work.
