our call

Start with Solidus — 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).

There is no licence to escape. Rebuilding makes sense only if you want to leave Ruby; otherwise you are trading a maintained core for a bespoke one.

you can rebuild

  • Catalog, variants and option types
  • Cart, checkout and order state machine
  • Promotions with basic rules and actions
  • Admin interface for orders and products

what you lose

  • A maintained upgrade path with a security-conscious core team
  • Rails extensions for payments, taxes and reporting
  • Free bug fixes from other people's production incidents
