our call
Start with Magento Open Source — highest vibe code, weakest moat.
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.
you can rebuild
- Standard e-commerce cart, checkout, and session management.
- Simple and configurable product catalog management.
- Basic promo engine and catalog discount rules.
- Admin panel CRUD operations for products, customers, and orders.
- OpenSearch/Elasticsearch catalog indexing and multi-attribute filters.
what you lose
- Access to thousands of off-the-shelf Magento extensions and ERP connectors.
- Pre-built integration agency support and developer network.
- Complex native multi-store inheritance and scoping engine.
- Out-of-the-box Varnish/Fastly full-page cache integration patterns.
- Built-in OpenSearch multi-attribute layered navigation indexing logic.
real moats
- Decades of legacy extension marketplace integrations (payments, ERPs, CRMs).
- Deep system-integrator agency ecosystem trained specifically on Magento architecture.
- Enterprise-grade multi-store scope inheritance logic across thousands of sub-domains.

Shopify
You can prompt an AI to spin up a slick Next.js store with Stripe checkout in 20 minutes, but you cannot prompt your way into a global commerce platform. Rebuilding Shopify means taking on PCI compliance, tax automation, carrier rate negotiation, 1-click buyer networks, and an ecosystem of 10,000+ app integrations.
