Start with Signifyd — highest vibe code, weakest moat.
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
real moats
- Proprietary cross-merchant global data pool with billions of analyzed transactions
- Financial backing to offer total chargeback insurance guarantees
- Deep risk-engine integration within major PSP transaction pipelines
open source escape hatches
- Hyperswitch Apache-2.0
- Zen Engine MIT
- FingerprintJS Open Source BSL-1.1
Signifyd
You can build the device fingerprinting script, rules engine, and Shopify order-hold webhook with AI in a weekend. What you cannot build is the bank balance required to reimburse merchants when your algorithm misclassifies a $3,000 stolen-card order.
you can rebuild
- Order hold and manual review queue automation
- Device fingerprinting and session analytics collection
- Custom risk-scoring rules engine (IP velocity, address matching, order value limits)
- Webhook routing to Shopify, Magento, and WooCommerce for order cancellation
- Basic chargeback notification webhook listeners
what you lose
- 100% financial chargeback guarantee on approved orders
- Access to Signifyd's 10,000+ merchant global identity graph

real moats
- Balance sheet reserves capable of liquidating millions in chargeback indemnifications monthly.
- Cross-merchant device and identity graph built over a decade across 10,000+ enterprise retailers.
- Direct integrations into card network early-warning feeds (Ethoca, Verifi, RDR).
