Cubyn vs Sifted
Cubyn ($1,500/mo/mo, vibe code 3/10) vs Sifted ($1,500/mo/mo, vibe code 4/10). Sifted is the easier one to rebuild yourself — here is what you lose either way.

our call
Start with Sifted — 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
- Physical inventory lock-in makes switching provider extremely costly
open source escape hatches
- OpenWMS Apache-2.0
- Apache OFBiz Apache-2.0
- ERPNext Logistics GPL-3.0
Sifted
Ingesting carrier CSVs and flagging late deliveries in a local database takes less than two weeks. However, automating claim submissions across anti-bot carrier portals and leveraging anonymized rate benchmarks from billions in shipping spend cannot be replicated in-house.
you can rebuild
- Carrier invoice CSV and flat-file parsing
- Basic tracking SLA breach detection
- Historical shipping spend breakdown by zone and service level
- Dimensional weight surcharge anomaly alerts
- Basic package volume and shipping cost reporting dashboards
what you lose
- Automated refund claim submission pipelines to carrier web portals
- Anonymized cross-shipper carrier rate benchmarking data
- Predictive contract modeling based on historic shipping profiles
- Handling of legacy carrier EDI 210/214 format updates
- Dedicated carrier negotiation advisory support
real moats
- Proprietary benchmark dataset of thousands of carrier contracts across billions in parcel spend
- Automated claim submission integrations resilient to carrier portal friction and anti-scraping changes
- Deep domain knowledge of carrier tariff schedules and seasonal surcharge rule-sets
Questions people ask
Which is easier to rebuild with AI, Cubyn or Sifted?
Sifted. It scores 4/10 on vibe code with a moat of 6/10, so an AI-assisted MVP takes about 2 weeks and a full replacement about 12-18 months, due to carrier API instability, EDI 210 parser edge cases, claim filing automation, and lack of cross-merchant rate benchmark data.
Which one costs less, Cubyn or Sifted?
Cubyn at $1,500/mo/mo for a typical mid-market store. The gap between the two is about usage-based a year.
