our call
Start with ShipEngine — highest vibe code, weakest moat.
Scurri
Building a shipping dashboard with basic routing rules takes a few days, but maintaining direct, certified connections to Royal Mail, DPD, Evri, and DHL requires strict barcode algorithms, daily electronic manifest protocols, and constant spec updates. One broken label layout halts warehouse packing lines.
you can rebuild
- Rule-based carrier allocation engine (e.g., routing by package weight or destination)
- Internal tracking dashboard for warehouse dispatch status
- Shopify/WooCommerce order pull via webhooks
- Normalized internal shipment status mapping
- Basic commercial invoice and packing slip PDF generation
what you lose
- Pre-certified API integrations with Royal Mail, DPD, Evri, An Post, and DHL
- Automated thermal printer ZPL code rendering certified by individual couriers
- Automated end-of-day electronic manifest transmission (EDI/REST) to carriers
- Cross-border customs document automation (paperless CN22/CN23/ETD)
- Direct carrier outage detection and fallback routing mechanisms
real moats
- Mandatory carrier developer certification and physical test label sign-offs
- Deeply ingrained warehouse hardware workflows (scanners, thermal label printers, packing stations)
- Extensive coverage of regional European and UK postal/courier networks

ShipEngine
Rebuilding a REST API wrapper for a single carrier like FedEx is straightforward, but ShipEngine normalizes hundreds of legacy carrier protocols into a single JSON schema. You cannot easily replicate CASS-certified address validation or maintain legacy carrier auth/ZPL output specs without endless operational drag.
you can rebuild
- Single-carrier label generation (e.g. direct EasyPost or FedEx API calls)
- Internal parcel tracking dashboard and status webhook handler
- Custom packing slip and invoice PDF generation
- Simple table-based or flat-rate shipping rule engine
- Basic shipping label batch creation scripts
what you lose
- Pre-negotiated USPS and UPS volume shipping discounts
- USPS CASS-certified address validation and DPV matching
- Unified JSON schema across 50+ international legacy shipping carriers
- Native thermal printer format compilation (ZPL II, EPL2, PNG, PDF)
- Automatic generation of paperless international customs forms (CN22/CN23/ETD)
real moats
- Aggregated volume tier discounts with major carriers passed down to developers
- Maintained certifications and direct carrier integration specs
- Licensed CASS postal databases for address normalization
