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
Sylius
Sylius is free; what you pay for is the Plus licence, the Symfony expertise and years of hardened cart, promotion and taxation code. An AI can generate a comparable core in weeks, but promotion rules and multi-channel pricing are where custom builds rot.
you can rebuild
- Catalog, taxon tree and product variant/option modelling
- Cart and checkout state machine with address and shipping steps
- Order, payment and shipment records with status transitions
- Admin CRUD screens for products, orders and customers
- Channel-based multi-currency and multi-locale storefronts
what you lose
- A battle-tested promotion engine with rule/action composition
- Symfony ecosystem bundles (workflow, security, messenger) already wired together
- The Sylius Plus features: RMA, multi-source inventory, B2B partner accounts
- A large pool of agencies and developers who already know the codebase
- Upstream security patches and LTS upgrade paths
real moats
- Agency and developer familiarity with the Symfony/Sylius conventions
- Plugin ecosystem covering payments, ERP connectors and marketplaces
- Years of edge cases baked into the promotion, tax and shipping engines
