our call
Start with Gr4vy — highest vibe code, weakest moat.
Gr4vy
Building a basic routing engine is straightforward, but replicating a secure, PCI-DSS Level 1 compliant token vault and dozens of gateway integrations requires continuous compliance audits and security overhead. Replacing Gr4vy with custom code introduces massive regulatory liability and integration maintenance burden.
you can rebuild
- Basic conditional payment routing rules engine
- Merchant admin dashboard for transaction monitoring
- Simple failover retry logic between two primary gateways
- Normalized unified checkout API schema
- Transaction metadata logging and analytics
what you lose
- PCI-DSS Level 1 compliant card data tokenization vault
- Out-of-the-box integrations with 50+ payment gateways and APMs
- Automatic 3D Secure 2 (3DS) / SCA step-up authentication handling
- Infrastructure isolation per merchant account
- Continuous API maintenance and compliance updates from payment providers
real moats
- PCI-DSS Level 1 certification and security liability absorption
- Broad pre-built integration catalog with PSPs, buy-now-pay-later (BNPL) providers, and fraud engines
- Universal token vaulting capable of cross-PSP token migration

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.

- 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
