our call
Start with Medusa — 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
Violet
Violet acts as a unified abstraction layer over incompatible e-commerce APIs like Shopify, WooCommerce, and BigCommerce. Building an abstraction API for a single platform is straightforward, but maintaining real-time cart synchronization, tax calculations, and payment delegation across dozens of dynamic platform versions is an operational sinkhole.
you can rebuild
- Single-platform catalog fetching wrapper
- Basic cart creation and line item updates
- Simple webhook payload ingest server
- Unified JSON schema mapper for basic product attributes
- Order status lookup proxy endpoint

- Maintained API adapters across Shopify, BigCommerce, WooCommerce, and Magento
- Unified cross-platform payment delegation and tokenization security
- Automated handling of upstream platform API breaking changes and deprecations
- Multi-merchant unified cart orchestration and checkout split logic
- Real-time rate limit management and webhook retry queues for dozens of stores
real moats
- Broad coverage of dynamic e-commerce API schemas and updates
- High-throughput OAuth app connections established across major e-commerce platforms
- Battle-tested payment token passing for secure merchant-of-record checkout routing
