our call
Start with Katana — highest vibe code, weakest moat.
Katana
You can build a simple assembly management UI and stock ledger with AI in a couple of weeks. Replicating full multi-level BOM explosion, FIFO lot traceability, landed cost rollups, and concurrent two-way integrations without database corruption requires months of production testing.
you can rebuild
- Basic single-level Bill of Materials (BOM) management.
- Purchase order auto-generation based on minimum inventory thresholds.
- Shop floor completion tracking UI and task scheduling.
- Sales order routing and multi-location inventory counts.
- CSV import/export for stock balances and item master lists.
what you lose
- Out-of-the-box Shopify, WooCommerce, QuickBooks, and Xero sync logic.
- Battle-tested lot traceability data records required during audit recalls.
- Pre-packaged Shop Floor mobile web app for assembly line workers.
- Automated multi-currency rate updates and landed cost accounting algorithms.
- 24/7 dedicated customer support and onboarding solutions engineering.
real moats
- Years of edge-case handling around inventory allocation concurrency and race conditions during high-volume sales.
- Pre-built, certified integrations with Shopify, QuickBooks Online, Xero, WooCommerce, and BigCommerce.
- Regulatory compliance trust for batch/lot recall histories in food, cosmetics, and medical industries.

ShipHero
ShipHero orchestrates hardware barcode scanners, local Zebra print servers (PrintNode/CUPS), dynamic warehouse pick path optimization, and multi-channel inventory allocations. While building a database for stock levels is straightforward, replacing physical warehouse floor execution and low-latency hardware integrations with an AI prompt is unrealistic.
you can rebuild
- Multi-channel inventory dashboard and stock level sync
- Purchase order creation and inventory receiving logs
- Manual order status updates to Shopify and BigCommerce
- Basic SKU-to-bin location catalog management
- Rules-based shipping carrier rate queries via aggregators
what you lose
- Native mobile barcode scanner app with offline-first scanning buffer
- Local print server daemon integration for instant thermal packing label prints
- Dynamic pick path route optimization algorithms for warehouse pickers
- Automated 3PL client billing, storage fees, and picking rate calculations
- Direct carrier integrations with batch shipping label generation engines
real moats
- Hardware-level integration with mobile barcode scanners and local thermal printers
- Row-level database concurrency locking for high-volume inventory allocations
- Deeply ingrained physical operational workflows for warehouse floor labor
