our call
Start with OpenCart — highest vibe code, weakest moat.
Medusa
Medusa is an open-source framework, meaning the underlying code is free and already available. Rebuilding a custom headless commerce engine from scratch via AI ignores years of edge-case bug fixes in checkout pipelines, multi-currency engines, and inventory locks.
you can rebuild
- Standard product catalog CRUD and variant management
- Basic cart creation and line-item management
- Simple Stripe payment intent integration
- Admin REST endpoints for order status updates
what you lose
- Access to hundreds of pre-built community plugins (search, payments, ERPs)
- The Medusa Admin dashboard and native Next.js starter storefronts
- Battle-hardened state machines for refunds, partial fulfillments, and split orders
- Managed, autoscaling deployment pipelines provided by Medusa Cloud
- Native TypeScript framework abstractions and extension points
real moats
- Massive open-source plugin ecosystem (Stripe, Algolia, Meilisearch, SendGrid, Contentful)
- Battle-tested workflow engine for complex multi-step cart, checkout, and fulfillment pipelines
- Active global developer ecosystem and plugin marketplace
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

- Cheap freelance support from developers who already know OpenCart
- Prebuilt payment and shipping modules for long-tail regional providers
- Community-tested upgrade scripts
real moats
- A long-tail extension marketplace covering regional payment and shipping providers
