our call
Start with Productsup — highest vibe code, weakest moat.

Building a sync engine for 1 or 2 specific marketplaces using AI coding tools is straightforward. Replacing ChannelEngine across dozens of global sales channels requires an engineering team dedicated solely to handling breaking API changes, unique taxonomies, and strict carrier SLAs.
you can rebuild
- Single-channel product listing exporter
- Basic order polling and injection into backend ERP/eCommerce system
- Simple static price markup rules per channel
- Basic stock level buffer calculations
- Rule-based field mapping between custom PIM and JSON APIs

- Instant access to 200+ pre-built, active marketplace connectors
- Continuous automated maintenance against breaking marketplace API changes
- Complex localized VAT and cross-border tax calculation logic
- Automated product attribute taxonomy transformers for major global channels
- Direct vendor relationships and SLA escalation channels with marketplace technical teams
real moats
- Ongoing operational upkeep of hundreds of third-party API endpoints and schemas
