our call
Start with Spree Commerce — highest vibe code, weakest moat.
BigCommerce
You can build a clean React shopping cart and a basic Node/Postgres backend with AI in a weekend. You cannot easily replace BigCommerce's deeply complex B2B pricing matrices, multi-inventory state machine, complex tax engines, or PCI-compliant checkout infrastructure without a massive ongoing engineering commitment.
you can rebuild
- Basic store frontend themes and responsive catalog display.
- Single-page checkout interface.
- Standard CSV product import/export tools.
- Basic customer group segmentation and manual coupon code engine.
- Simple multi-currency display and manual rate overrides.
what you lose
- Out-of-the-box PCI-DSS Level 1 compliant hosted checkout infrastructure.
- Native B2B enterprise suite (company account hierarchies, invoice payment terms, custom price lists).
- Deep pre-built integrations with top ERPs, POS systems, and tax services (Avalara, Vertex).
- 24/7 dedicated enterprise infrastructure monitoring and SLA guarantees.
- Access to Feedonomics surface for automated multi-channel marketplace feed management.
real moats
- Decade-long ecosystem of native ERP, CRM, and fulfillment integrations (Acumatica, NetSuite, SAP).
- Built-in enterprise B2B functionality (Company accounts, net terms, custom price lists, buyer permissions).
- Turnkey compliance stack (PCI-DSS Level 1, SOC 2 Type II, ISO 27001).

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
