our call
Start with Medusa — highest vibe code, weakest moat.
Medusa
Medusa is an open-source framework, meaning the underlying code is free and already available. Rebuilding a custom headless commerce engine from scratch via AI ignores years of edge-case bug fixes in checkout pipelines, multi-currency engines, and inventory locks.
you can rebuild
- Standard product catalog CRUD and variant management
- Basic cart creation and line-item management
- Simple Stripe payment intent integration
- Admin REST endpoints for order status updates
what you lose
- Access to hundreds of pre-built community plugins (search, payments, ERPs)
- The Medusa Admin dashboard and native Next.js starter storefronts
- Battle-hardened state machines for refunds, partial fulfillments, and split orders
- Managed, autoscaling deployment pipelines provided by Medusa Cloud
- Native TypeScript framework abstractions and extension points
real moats
- Massive open-source plugin ecosystem (Stripe, Algolia, Meilisearch, SendGrid, Contentful)
- Battle-tested workflow engine for complex multi-step cart, checkout, and fulfillment pipelines
- Active global developer ecosystem and plugin marketplace
Sana Commerce
AI can build the front-end B2B portal, quote flow, and cart in a few afternoons. However, Sana's entire enterprise business is built around deep, proprietary ERP web service integration with SAP and Microsoft Dynamics that runs natively inside ERP codebases.
you can rebuild
- B2B Customer Portal UI (Order history, invoice downloads, account balances).
- Quote-to-order conversion workflows and sales agent order-on-behalf-of impersonation.
- Customer-specific catalog presentation and segment-based navigation menus.
- RMA (Returns & Refunds) request forms and status tracking.
- B2B quick-order grids, CSV order upload, and re-order lists.
what you lose
- Native in-ERP add-ons (AL extensions for Dynamics 365, ABAP objects for SAP) that expose ERP pricing and business logic safely via web services.
- Out-of-the-box integration with legacy ERP systems (SAP ECC, NAV, AX, Business One).
- Battle-tested ERP failover handling and transaction lock protection.
- Certified enterprise security and compliance standards required for ERP data exposure.
- Automated multi-currency, multi-entity tax and credit check logic embedded in enterprise financial modules.
real moats
- Pre-packaged enterprise ERP integrations (proprietary ABAP modules for SAP and C/AL or AL extensions for Dynamics) tested against 20+ years of ERP version quirks.
- Real-time pricing and stock engine capable of executing complex ERP logic (trade agreements, matrix discounts, dynamic tax calculation) without crashing enterprise ERPs under heavy load.
- Deep industry reputation and certified partner network with SAP and Microsoft Dynamics integrators.
