our call
Start with Spree Commerce — highest vibe code, weakest moat.
Spree Commerce
Spree is free code you already own. Rebuilding it in a modern stack is realistic; you inherit the maintenance and lose the Rails extension ecosystem.
you can rebuild
- Catalog, taxonomy and variant modelling
- Cart and multi-step checkout
- Order, shipment and return records
- Admin CRUD screens
- Multi-store and multi-currency basics
what you lose
- The Rails extension ecosystem (payments, subscriptions, analytics)
- Years of accumulated promotion and tax edge cases
- Upstream security releases
- Developers who already know the API surface
real moats
- Extension ecosystem and long-running community
- Accumulated commerce edge cases in tax, promotions and returns
open source escape hatches
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
