our call
Start with Commerce Layer — highest vibe code, weakest moat.
Commerce Layer
While building a CRUD shopping cart with Node.js and Postgres is straightforward, Commerce Layer's value lies in localized pricing engines, inventory reservations across global warehouses, and resilient payment gateway webhooks. Rebuilding this infrastructure introduces high risk for tax non-compliance, overselling stock, and payment edge-case failures.
you can rebuild
- Basic cart state and line item CRUD operations
- Simple discount code matching and validation
- Basic SKU and price lookup endpoints
- Customer address book management
- Simple order status tracking history
what you lose
- Multi-market architecture with per-geography currency and tax rules
- Real-time inventory reservation and multi-warehouse allocation
- Pre-built PCI-compliant hosted checkout micro-apps
- Native multi-gateway payment orchestration (Stripe, Adyen, Klarna, PayPal)
- Idempotent webhook engine for enterprise ERP/OMS synchronization
real moats
- Deep API integration lock-in across CMS and frontend codebases
- Battle-tested transactional resilience for high-concurrency flash sales
- Pre-certified PCI-DSS compliance scope reduction for custom checkouts

Sanity
Rebuilding simple JSON storage with an admin UI is straightforward, but Sanity is a complex real-time document database with collaborative editing (OT/CRDT), custom GROQ query engine, and dynamic asset processing pipelines. Replacing its infrastructure from scratch introduces massive engineering overhead for zero commercial gain.
you can rebuild
- JSON document CRUD storage
- Basic draft vs. published state machine
- Simple webhooks on content change
- Role-based permission checks
- Form schema generation from code
what you lose
- Real-time collaborative document editing with conflict resolution
- GROQ dynamic query language with deep references
- Sanity Image Pipeline (instant focal point cropping and resizing on CDN)
- Server-Sent Events (SSE) live content preview streams
- Sanity Studio customizable React editorial UI framework

- Deep developer workflow lock-in via custom GROQ queries

Questions people ask
Which is easier to rebuild with AI, Commerce Layer or Sanity?
Commerce Layer. It scores 5/10 on vibe code with a moat of 4/10, so an AI-assisted MVP takes about 2 weeks and a full replacement about 9-12 months, due to localized tax, multi-currency inventory locking, payment orchestration, and webhook failure recovery.
Which one costs less, Commerce Layer or Sanity?
Sanity at $300/mo/mo for a typical mid-market store. The gap between the two is about $1,800/mo a year.
