our call
Start with Spree Commerce — highest vibe code, weakest moat.
CommerceTools
CommerceTools is an enterprise-grade, microservice-based commerce engine built for global scale and massive concurrency. An AI can easily mock its REST/GraphQL endpoint structure, but building a system that reliably processes millions of orders with high-availability SLAs, distributed locks, and strict compliance is an infrastructure effort taking years.
you can rebuild
- CRUD operations for Product Catalogs, Categories, and Attributes.
- Standard Cart management and checkout session orchestration.
- Basic customer account management and address books.
- REST and GraphQL API wrapper definitions.
- Discount and promo code evaluation logic.
what you lose
- 99.99% availability SLAs during peak global sales events.
- Turnkey PCI-DSS Level 1, SOC2, and HIPAA compliance guarantees.
- Managed infrastructure, multi-region database scaling, and auto-scaling APIs.
- Access to a vast network of system integrators and certified partner developers.
- Pre-built integrations with major enterprise ERPs, OMSs, and PIMs.
real moats
- Infrastructure reliability: Proven capability to handle flash sales with high API throughput.
- Enterprise certifications: Pre-packaged SOC2, PCI-DSS Level 1, and HIPAA compliance.
- Partner ecosystem: Hundreds of SI agencies trained to deploy and maintain CommerceTools implementations.
- Global multi-tenant data architecture supporting multi-region deployment out of the box.
Spree Commerce
Spree is free code you already own. Rebuilding it in a modern stack is realistic; you inherit the maintenance and lose the Rails extension ecosystem.
you can rebuild
- Catalog, taxonomy and variant modelling
- Cart and multi-step checkout
- Order, shipment and return records
- Admin CRUD screens
- Multi-store and multi-currency basics
what you lose
- The Rails extension ecosystem (payments, subscriptions, analytics)
- Years of accumulated promotion and tax edge cases
- Upstream security releases
- Developers who already know the API surface
real moats
- Extension ecosystem and long-running community
- Accumulated commerce edge cases in tax, promotions and returns
