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
