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

Sentry
While building a basic web portal to store JSON errors takes a weekend, replicating Sentry's sourcemap symbolication, stack-frame demangling, high-throughput ingest, and fingerprint grouping is a multi-year infrastructure effort. Do not build this; use Sentry or self-host GlitchTip.
you can rebuild
- Basic API endpoint ingestion for custom HTTP error payloads
- Simple stack trace rendering UI in React
- Basic Slack and webhook alerting on unhandled exceptions
- Simple error counting and CRUD issue status management
what you lose
- Native client SDKs across iOS, Android, React Native, Python, Go, and Ruby with automatic context/breadcrumb capture.
- Automated sourcemap symbolication and stack-frame demangling out of the box.
- Seer AI root-cause analysis and automated fix generation linked directly to GitHub/GitLab commits.
- Intelligent issue grouping algorithms refined across trillions of real-world exceptions.
- Session Replay, continuous CPU/memory profiling, and trace span monitoring.
real moats
- Decade-long investment in battle-tested client SDKs covering 30+ programming languages and frameworks.
- Proprietary error fingerprinting algorithms fine-tuned over billions of exceptions to group identical bugs accurately.
- Seer AI code-context grounding models trained on deep stack trace historical datasets.

Questions people ask
Which is easier to rebuild with AI, AppMachine or Sentry?
AppMachine. It scores 7/10 on vibe code with a moat of 1/10, so an AI-assisted MVP takes about 1 weekend and a full replacement about 3-4 weeks, including Apple/Google app store approval and push notification setup.
Which one costs less, AppMachine or Sentry?
Sentry at $80/mo/mo for a typical mid-market store. The gap between the two is about $228/mo a year.
