our call
Start with Spree Commerce — highest vibe code, weakest moat.
Shopify
You can prompt an AI to spin up a slick Next.js store with Stripe checkout in 20 minutes, but you cannot prompt your way into a global commerce platform. Rebuilding Shopify means taking on PCI compliance, tax automation, carrier rate negotiation, 1-click buyer networks, and an ecosystem of 10,000+ app integrations.
you can rebuild
- Basic product catalog and variant management
- Standard web storefront and cart drawer UI
- Basic order lifecycle tracking (Unfulfilled -> Fulfilled)
- Simple Stripe checkout integration
- Basic customer accounts and address book
what you lose
- Shop Pay's ultra-high-converting 1-click checkout network.
- Pre-negotiated carrier shipping discounts (up to 87% off).
- Instant access to 10,000+ pre-built App Store integrations.
- Out-of-the-box global sales tax calculation and automated compliance reporting.
- Turnkey point-of-sale hardware integration for physical retail locations.
real moats
- Shop Pay conversion performance across hundreds of millions of saved buyer wallets.
- Global tax engine and built-in regulatory compliance (Shopify Tax / EU VAT).
- Massive multi-channel distribution network (Shop App, Google, Meta, TikTok native checkouts).
- Deeply integrated financial products (Shopify Payments, Capital, Balance, Installments).

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
