our call
Start with Tapcart — highest vibe code, weakest moat.
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
real moats
- Deep developer workflow lock-in via custom GROQ queries
- Highly tailored editorial Studio UIs embedded in team workflows
- Proprietary real-time Content Lake sync backend

Tapcart
Building a custom React Native mobile app for a single Shopify store using the Storefront API is straightforward with AI. Rebuilding Tapcart's drag-and-drop mobile visual editor, automated App Store build pipelines, and 50+ pre-built SaaS app integrations is a massive engineering effort.
you can rebuild
- Shopify Storefront API catalog browsing and product page rendering
- Native mobile cart state management and checkout webview handoff
- Basic push notification sending via Firebase Cloud Messaging
- Customer authentication, account viewing, and order tracking
- Mobile home screen product collections and grid displays
what you lose
- No-code drag-and-drop layout builder for non-technical marketing staff
- Automated iOS and Android binary compilation and App Store submission CI/CD
- Pre-built integrations with Shopify ecosystem tools (Klaviyo, Recharge, Yotpo, Smile)
- Turnkey push notification automation triggered by Shopify webhooks (abandoned cart, order status)
- App Store policy compliance handling and mobile push token lifecycle management
real moats
- Automated App Store build, signing, and submission infrastructure
- Turnkey integration network across dozens of proprietary ecommerce SaaS APIs
- High switching cost resulting from native app store distribution and registered push tokens
