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

Tamara
Tamara is a licensed financial institution backed by massive balance sheets, credit scoring infrastructure, and local regulatory licenses (such as SAMA in Saudi Arabia). Writing an installment payment UI takes a weekend, but absorbing default risk and holding debt capital cannot be done with code.
you can rebuild
- Checkout installment option widget
- Scheduled payment auto-charge logic
- Installment schedule ledger database schema
- Merchant payment tracking dashboard
- Automated SMS and email payment reminders
what you lose
- SAMA and CBUAE BNPL regulatory compliance and licenses
- Zero-risk merchant payouts where Tamara covers consumer default risk
- Access to millions of GCC consumers browsing the Tamara shopping directory
- Direct API integrations with regional credit scoring bureaus like SIMAH
- Institutional debt facilities to finance consumer purchase balances
