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

Tabby
Tabby is not a software tool; it is a licensed financial institution and credit provider operating in the GCC. While building an installment math widget takes an afternoon, underestimating the capital reserves, credit bureau integrations, and central bank regulations required will kill the project immediately.
you can rebuild
- Checkout installment pricing preview widget
- Merchant analytics and settlement dashboard
- Plugin integrations for Shopify and WooCommerce
- Webhook notifications for payment capture and refunds
- Order status synchronization and tracking links
what you lose
- Capital balance sheet to fund customer purchases upfront
- Regulatory BNPL licenses from SAMA (Saudi Arabia) and CBUAE (UAE)
- Real-time integrations with regional credit bureaus (SIMAH, AECB)
- Consumer shopping app marketplace driving direct acquisition traffic
- Automated collections infrastructure and delinquency management
