FraudNet vs Subuno
FraudNet ($899/mo/mo, vibe code 5/10) vs Subuno ($149/mo/mo, vibe code 6/10). Subuno is the easier one to rebuild yourself — here is what you lose either way.

our call
Start with Subuno — highest vibe code, weakest moat.
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

Subuno
Subuno's underlying tech is an IF/THEN rules engine connected to third-party identity/risk lookup services. Rebuilding the UI and rule execution in Node.js is trivial, but maintaining contracts, schema mappings, and API keys for a dozen external fraud vendors is not worth the overhead for most merchants.
you can rebuild
- Custom IF/THEN rule engine for flagging high-risk orders
- Manual order review queue with approve/reject actions
- Email alerts and webhook triggers for flagged transactions
- Basic IP geolocation and address verification (AVS) checks
- Custom merchant-defined whitelists and blacklists
what you lose
- Pre-integrated access to 15+ external fraud data providers
- Unified billing and unified payload normalization across third-party identity APIs
- Cross-merchant shared bad-actor detection network
- Zero-maintenance e-commerce store platform plugins
- Turnkey automated order status updating in connected store platforms
real moats
- Aggregated integration maintenance across a broad mesh of specialized risk APIs
- Cross-merchant shared blacklists and fraud signal history
- Low subscription fee relative to managing multi-vendor API overhead directly

Questions people ask
Which is easier to rebuild with AI, FraudNet or Subuno?
Subuno. It scores 6/10 on vibe code with a moat of 3/10, so an AI-assisted MVP takes about 1 week and a full replacement about 6-12 months, due to third-party API integration maintenance and continuous rule optimization.
Which one costs less, FraudNet or Subuno?
Subuno at $149/mo/mo for a typical mid-market store. The gap between the two is about $9,000/mo a year.
