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).

- Saleor BSD-3
- WooCommerce GPL-3.0
Shopify Plus
An AI can rebuild the admin screens of Shopify Plus in weeks. It cannot rebuild Shop Pay, the Black Friday capacity guarantee, the checkout extensibility sandbox, or the contractual SLA that makes a CFO sign off on $2,300+/mo.

- Out-of-scope PCI-DSS: Shopify holds the card data, you do not.
- Multi-store organisation management with shared catalog and centralised roles.
