our call
Start with Solidus — 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.
Solidus
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
