our call

Start with Carted — highest vibe code, weakest moat.

Carted

Carted handles complex cross-merchant cart aggregation, payment tokenization forwarding, and real-time inventory verification across dozens of e-commerce backends. Building a single-store checkout in Claude is trivial, but an agentic universal checkout network requires maintaining fragile connectors against changing merchant APIs and payment gateways.

you can rebuild

  • Embeddable HTML/React checkout buttons and overlay modals
  • Basic multi-product cart UI state management in the browser
  • Order confirmation email dispatch via transactional email providers
  • Unified JSON cart payload schema generation for client apps
  • Basic affiliate link/referral tracking attribution tag injection

what you lose

  • Universal multi-merchant cart aggregation and split-payment execution engine
  • PCI-compliant payment token delegation across third-party merchant gateways
  • Real-time product availability, pricing, and variant validation across external platforms
  • Pre-built resilient API connectors for Shopify, BigCommerce, Magento, and WooCommerce
  • Automated edge-case handling for merchant-specific taxes, shipping rules, and discount codes

real moats

  • Resilient adapter layer mapping unified checkout endpoints to hundreds of non-standard merchant backends
  • PCI-DSS compliant proxy infrastructure capable of delegating payment tokens safely across third-party processors
  • Direct technical and commercial partnerships with major commerce platforms and enterprise publishers

Limepay

Limepay is not merely a checkout UI widget; it is a payment service provider and credit facilitator. While crafting the front-end embedded form is trivial, AI cannot generate PCI-DSS Level 1 certification, banking acquiring licenses, underwriting engines, or the balance sheet capital required for BNPL payouts.

you can rebuild

  • Embedded white-label checkout modal and inline form widgets
  • On-site installment payment calculation preview widgets
  • Custom merchant branding and checkout flow configuration
  • Admin dashboard for viewing transaction history and order statuses
  • Basic customer payment plan schedule display

what you lose

  • PCI-DSS Level 1 compliant card tokenization and secure vaulting infrastructure
  • Underwriting and real-time credit risk engines for installment approvals
  • Direct balance sheet funding for upfront merchant payouts on installment plans
  • Automated fraud mitigation and chargeback resolution management
  • Financial regulatory licensing, KYC, and AML compliance coverage

real moats

  • PCI-DSS Level 1 certification and bank acquiring network agreements
  • Capital lines and balance sheet liquidity required to fund consumer credit upfront
  • Proprietary risk scoring algorithms trained on historical default data
