our call
Start with Eye4Fraud — highest vibe code, weakest moat.
Eye4Fraud
Building a rule engine for fraud scoring in Cursor takes days, but Eye4Fraud's core value is financial insurance and global intelligence. AI cannot write checks to cover $5,000 chargeback disputes when a stolen card slips through custom rules.
you can rebuild
- Basic order risk scoring engine
- Rules-based transaction flagging (AVS, CVV, IP matching)
- Customer order review dashboard for operations staff
- Email notifications for suspicious order holds
- E-commerce platform webhook listeners for pending orders
what you lose
- 100% chargeback guarantee and financial reimbursement
- Cross-merchant network intelligence on stolen identity reuse
- Human fraud analyst manual review service
- Automated dispute handling and representation with banks
- Device fingerprinting database across thousands of stores
real moats
- Financial underwriting capacity to absorb chargeback losses
- Proprietary cross-merchant fraud graph and device telemetry
- Human analyst operations network for edge cases

Fraugster
While creating a basic risk rules engine and order-scoring dashboard takes days, Fraugster's core value is an ML model trained on billions of cross-merchant transactions. Building the software wrapper is trivial, but without global data pools and chargeback coverage, your DIY fraud engine will bleed money to chargebacks or block legit orders.
you can rebuild
- Custom boolean rule engine (e.g., flag if shipping address != billing country)
- Manual order review dashboard and analyst decision workflows
- Basic IP geolocation and transaction velocity rate-limiting
- Webhook triggers to hold or cancel suspicious orders in Shopify/Magento
- Email domain risk checking against disposable email provider lists
what you lose
- Cross-merchant network intelligence that spots device signatures across thousands of global stores
- Financial chargeback coverage and fraud loss liability guarantees
- Real-time supervised machine learning models trained on historical chargeback data
- Advanced canvas device fingerprinting and proxy/VPN detection logic
- 3D Secure 2.0 dynamic step-up authentication orchestration
