our call
Start with FraudBlock — highest vibe code, weakest moat.
FraudBlock
FraudBlock does not calculate fraud risk itself; it acts on Shopify's native order risk assessment. Rebuilding it requires a single serverless webhook handler that checks order risk levels and invokes the Shopify API to void, cancel, and restock.
you can rebuild
- Automatic cancellation of High Risk orders flagged by Shopify
- Automatic inventory restocking for cancelled orders
- Customer email notification suppression or customization on cancel
- Payment authorization voiding and refund triggering
- Custom whitelist/blacklist rules for customer emails or IP addresses
what you lose
- Turnkey Shopify App Store single-click installation
- Pre-built embedded UI inside Shopify Admin
- Managed serverless infrastructure maintenance and webhook listener uptime
- Off-the-shelf audit log for cancelled orders
- No-code toggle for inventory restock rules
real moats
- Shopify App Store distribution friction
- Extremely low price point making dev effort debatable for tiny stores
FraudNet
Building a rule engine with MaxMind or Radar APIs takes a weekend, but you cannot replicate FraudNet's global network of shared fraud signals and device fingerprint intelligence. Without global transaction data across thousands of stores, custom AI models hallucinate or generate false positives that destroy legitimate conversion.
you can rebuild
- Rule-based transaction scoring engine (e.g., velocity checks, threshold limits)
- Order risk review dashboard and manual approval workflow
- Blacklisting and whitelisting by email, IP, shipping address, or BIN
- Basic geo-IP mismatch detection and address verification triggers
- Webhook alerts and automated order holding in Shopify or WooCommerce
what you lose
- Cross-merchant network intelligence tracking fraud rings across thousands of stores
- Proprietary device fingerprinting heuristics bypassing browser privacy protections
- Chargeback guarantee coverage options that shift financial liability away from you
- Real-time proxy, VPN, TOR, and residential botnet IP reputation databases
- Continuous machine learning model retrain cycles backed by global dispute feeds
real moats
- Cross-merchant consortium data linking malicious devices and emails across clients
- Proprietary device fingerprinting scripts resilient to modern privacy browsers
- Chargeback liability shifting and financial guarantee models
open source escape hatches
- Zen Engine MIT
- Grule Rule Engine Apache-2.0
- Apache Fineo / Open Threat Feeds Apache-2.0
