Magento Open Source
AI can effortlessly write a lightweight e-commerce platform that replaces Magento's standard shopping cart and catalog functionality. However, fully replicating Magento's architectural depth—including multi-store scope inheritance, complex variant logic, and its vast library of legacy third-party extensions—is a massive software engineering endeavor.
