our call
Start with Spree Commerce — highest vibe code, weakest moat.
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.
you can rebuild
- Admin dashboard, catalog and variant management
- Discount and promotion rule engine
- Order and fulfilment workflow screens
- B2B company accounts and custom price lists for a handful of buyers
- Wholesale/expansion storefront as a separate lightweight site
what you lose
- Shop Pay's saved-wallet 1-click checkout and its measurable conversion lift.
- Contractual 99.99% uptime SLA and Black Friday capacity planning.
- Checkout extensibility and Shopify Functions running server-side at the edge.
- Out-of-scope PCI-DSS: Shopify holds the card data, you do not.
- Multi-store organisation management with shared catalog and centralised roles.
real moats
- Shop Pay buyer network with hundreds of millions of saved wallets.
- Peak-event infrastructure proven at millions of checkouts per minute.
- Payments, Capital, Balance and Installments bundled into the same contract.
- App and agency ecosystem trained specifically on the Plus extension model.
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
