Start with Rebuy — highest vibe code, weakest moat.
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
