our call
Start with Cubyn — highest vibe code, weakest moat.
Cubyn
Cubyn is an asset-backed 3PL service integrated with software. While building a dashboard to aggregate carrier APIs takes days, code cannot pick boxes, store physical inventory, or match Cubyn's negotiated bulk shipping rates.
you can rebuild
- Multi-carrier shipping label generation API
- Package tracking page and status webhook aggregator
- Ecommerce platform order synchronization
- Basic inventory level reporting dashboard
- Address validation and normalization
what you lose
- Physical warehouse storage and fulfillment operations
- Pre-negotiated bulk carrier discounts across EU networks
- Same-day order pick and pack operational SLAs
- Physical return handling and item inspection
- Claims management for lost or damaged physical shipments
real moats
- Physical warehouse network infrastructure and warehouse management systems
- Negotiated carrier rate contracts leveraging massive aggregate shipping volume

open source escape hatches
- OpenWMS Apache-2.0
- Apache OFBiz Apache-2.0
- ERPNext Logistics GPL-3.0
Flexport
Flexport is a physical logistics company wrapped in modern software, not a pure SaaS product. While you can build a container tracking interface with an AI agent in a weekend, code cannot negotiate ocean liner rates, operate fulfillment centers, or file customs documentation with federal agencies.
you can rebuild
- Purchase order management and allocation portal
- Shipment status visualization and milestone timeline
