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
real moats
- A long-tail extension marketplace covering regional payment and shipping providers
- Low-cost freelancer supply familiar with the codebase
Swell
A headless commerce API is a well-understood build. What Swell sells is not having to run it: uptime, dashboard, subscription billing and payment plumbing maintained by someone else.
you can rebuild
- Products, variants and pricing rules via API
- Cart, checkout session and order APIs
- Customer accounts and saved payment methods
- Webhook events for downstream systems
- A basic merchant dashboard
what you lose
- A maintained subscription billing engine with retries and dunning
- Hosted uptime and scaling during traffic spikes
- Prebuilt payment, tax and shipping integrations
- A dashboard non-developers can operate
real moats
- Maintained integrations across payments, tax and shipping
- Subscription billing correctness accumulated across merchants
- Operational reliability you would otherwise staff for
