our call
Start with OpenCart — highest vibe code, weakest moat.
OpenCart
OpenCart is a compact MVC cart. AI can produce a cleaner equivalent quickly, and you skip a decade of legacy PHP. You lose the paid extension marketplace and the freelancer pool that knows it.
you can rebuild
- Product, option and category management
- Cart, checkout and order lifecycle
- Customer accounts, wishlists and order history
- Basic admin dashboard and reports
- Multi-language and multi-currency storefronts
what you lose
- 13,000+ marketplace extensions and themes
- Cheap freelance support from developers who already know OpenCart
- Prebuilt payment and shipping modules for long-tail regional providers
- Community-tested upgrade scripts

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.

- Discount and promotion rule engine
- Order and fulfilment workflow screens
