our call
Start with Rebuy — highest vibe code, weakest moat.
Global-e
Global-e is primarily a Merchant of Record (MoR) and cross-border regulatory provider, not just a software overlay. While you can easily code a multi-currency checkout frontend with AI, you cannot code local tax registrations in 180 countries, customs clearance agreements, or FX risk hedging contracts.
you can rebuild
- Multi-currency price rounding and display logic
- Geo-IP country detection and checkout localization
- Localized checkout field formatting and address validation UI
- Basic front-end duty and tax estimation UI widgets
- Integration with third-party payment gateways for basic foreign card handling
what you lose
- Merchant of Record status and legal tax liability indemnification
- Global tax entity registrations (VAT/GST compliance) in over 180 markets
- Pre-negotiated international courier rates and duty drawback processing
- FX rate risk hedging and localized foreign currency payout management
- Local payment method acquiring networks that increase approval rates
real moats

- Established volume-discounted agreements with international logistics carriers and customs brokers
- Direct local payment acquiring relationships that boost cross-border conversion
Rebuy
You can easily build a custom slide-out cart and a basic Shopify Checkout UI Extension using modern AI coding agents in a weekend. However, duplicating Rebuy's cross-app integrations, ML recommendation graphs, and cross-channel merchandising flows requires significant long-term maintenance.
