It’s using AISDK and MCP-UI, which is standard for chats. If you check the cart in the input, there’s only 2 stores added for now.
Also, that chat is just one part of it. Those stores are running on Openfront, our Shopify alternative. Please check our ethos to get the full vision.
Also, I was working on this before AI. Openfront and the/marketplace are part of an ecosystem. We built Openship, an e-commerce order management system, years ago.
