our call
Start with Primer — highest vibe code, weakest moat.
Checkout.com
Checkout.com is a licensed electronic money institution and direct card acquirer. While you can use AI to build a custom checkout UI or smart payment router over existing gateways, replacing Checkout.com's underlying infrastructure requires direct card scheme access, HSM vaults, and global regulatory compliance.
you can rebuild
- Custom checkout UI components and form fields
- Transaction status dashboards and reporting views
- Basic webhook processing and event logging
- Rule-based payment gateway routing logic
- Simple rule-based fraud screening pre-checks
what you lose
- Direct Visa/Mastercard scheme acquiring and settlement
- PCI DSS Level 1 certified tokenization and HSM vaulting
- Access to 150+ regional payment methods (e.g. iDEAL, Pix, Sofort)
- Native 3D Secure 2 (3DS2) protocol and exemption engine
- Multi-jurisdiction electronic money and payment institution licenses
real moats
- Payment institution licenses and regulatory compliance across global jurisdictions
- Direct card scheme memberships and bank clearing house connections
- PCI DSS Level 1 security infrastructure and HSM key management

Primer
Building basic logic to failover between Stripe and Adyen in Node.js takes a few days. However, Primer provides PCI-DSS Level 1 card vaulting, 3DS2 orchestration, unified tokenization, and dozens of pre-built payment connectors. Replacing Primer with custom code creates massive regulatory and engineering overhead.
you can rebuild
- Basic conditional payment routing (if Gateway A fails, try Gateway B)
- Rule-based PSP selection by buyer currency or country
- Basic payment transaction logging and status dashboard
- Dynamic surcharge calculations based on payment method
- Centralized webhook aggregation for payment status events
what you lose
- PCI-DSS Level 1 compliant card tokenization vault
- Pre-built integrations for 100+ PSPs, BNPLs, and alternative payment methods
- Native 3DS2 (Strong Customer Authentication) flow orchestration across gateways
- No-code visual drag-and-drop payment workflow automation editor
- Unified financial reconciliation and automated payout matching across processors
real moats
- PCI-DSS Level 1 security architecture and ongoing audit compliance
- Universal card vaulting and token format translation between legacy gateways
- Battle-tested maintenance of dozens of volatile payment processor APIs
