our call
Start with Duoplane — highest vibe code, weakest moat.
Duoplane
Duoplane's fundamental feature—splitting orders by vendor and emailing purchase orders—can be built with an AI coding agent in a weekend. However, if your suppliers require legacy protocols like EDI X12, custom SFTP CSV parsing, or email scraping, maintaining custom pipelines becomes expensive fast.
you can rebuild
- Automatic splitting of customer orders into vendor-specific purchase orders
- PDF purchase order generation and automated vendor email dispatch
- Vendor self-service portal for updating tracking numbers and stock levels
- SKU-to-supplier catalog mapping with wholesale margin configuration
- Automated shipment tracking synchronization back to the storefront API
what you lose
- Pre-built support for EDI X12 automated order transmission
- Built-in SFTP file polling and schema normalization for non-technical vendors
- Automated PDF invoice parsing from supplier email replies
- Out-of-the-box vendor accounting and cost of goods sold reconciliation logic
- Multi-store unified routing rules engine across different e-commerce platforms
real moats
- Broad integration coverage for legacy supplier communications (SFTP, EDI, legacy email schemas)
- Operational lock-in via custom supplier workflow rules built over time
- Handling complex edge cases like partial shipments, split shipping tax calculations, and backorders

Linnworks
You can easily build a custom OMS that handles inventory allocation and shipping for 2-3 core channels using modern AI dev tools in a couple of weeks. However, replicating Linnworks' entire footprint—which includes 100+ pre-built marketplace APIs, regional shipping integrations, and a deeply embedded warehouse management system—takes years of ongoing maintenance.
you can rebuild
- Basic multi-channel order ingestion and centralized viewing dashboard.
- Simple inventory level tracking and automated deduction upon order creation.
- Basic shipping label printing via carrier API abstractions like EasyPost or ShipEngine.
- Simple rule-based shipping carrier assignment (e.g., weight/destination routing).
- Purchase order generation and low-stock reorder thresholds.
what you lose
- Access to 100+ pre-configured marketplace channel connectors (TikTok Shop, Temu, Allegro, Back Market, eBay, Amazon).
- Native SkuVault warehouse management system (WMS) features like barcode-guided digital picking and bin location tracking.
- Pre-built integrations with dozens of international and regional freight/parcel shipping carriers.
- Turnkey demand forecasting tools and historic reporting models out of the box.
- Dedicated onboarding engineers and guaranteed SLA support for high-volume enterprise operations.
real moats
- Deep library of fragile, proprietary channel and carrier API integrations built over 15+ years.
- High switching costs once warehouse workflows, hardware integrations, and staff routines are anchored to Linnworks.
- Comprehensive handling of edge cases across multi-warehouse bin locations, bundle decompositions, and international logistics customs data.

Questions people ask
Which is easier to rebuild with AI, Duoplane or Linnworks?
Duoplane. It scores 6/10 on vibe code with a moat of 3/10, so an AI-assisted MVP takes about 1-2 weeks and a full replacement about 6-12 months, due to legacy supplier integrations (FTP/EDI/Email format fragmentation).
Which one costs less, Duoplane or Linnworks?
Duoplane at $499/mo/mo for a typical mid-market store. The gap between the two is about $8,412/mo a year.
