our call

Start with AppMachine — highest vibe code, weakest moat.

AppMachine

AppMachine sells generic block-based mobile app generation for stores. You can use Cursor or Claude with React Native and Expo to build a clean, custom native app connected directly to your Shopify or WooCommerce APIs without monthly platform fees.

you can rebuild

  • Product catalog native listing views
  • Shopify/WooCommerce REST API cart sync
  • Push notification triggers via Firebase/OneSignal
  • User login and order history views
  • Embedded webview checkout fallback

what you lose

  • No-code visual block layout editor
  • Automated App Store cloud submission pipeline
  • Pre-built layout templates for non-technical users
  • Multi-app dashboard for agency client management
  • Instant live app layout updating without app store resubmission

real moats

  • Automated iOS/Android app store build and deployment pipeline
  • Dynamic layout remote-rendering engine
  • Agency multi-tenant client management UI

eCartApi

While building a single standardized schema wrapper for 2-3 carts takes days, maintaining auth, webhooks, and breaking API updates across 30+ platforms requires dedicated engineering bandwidth. You aren't paying for complex algorithms; you are paying for platform adapter maintenance and rate limit handling.

you can rebuild

  • Unified JSON schema mapping for product and order payloads
  • Developer dashboard for API credential and token management
  • Webhook relay and event standardizing across platforms
  • Basic REST proxy middleware between application and cart endpoints
  • Request and response logging with audit trails

what you lose

  • Pre-built connectors and OAuth flows for 30+ ecommerce platforms
  • Automatic maintenance for third-party API version deprecations and breaking changes
  • Built-in rate limiting queues and platform throttling management
  • Unified error handling and standardized response normalization
  • Managed infrastructure for secure third-party store token storage

real moats

  • Massive ongoing engineering footprint to maintain 30+ cart API adapters
  • High integration lock-in once app backend relies on unified endpoints
  • Platform version deprecation tracking and automated fallback handling
