our call
Start with Subuno — highest vibe code, weakest moat.
FraudLabs Pro
Coding a custom rule evaluation engine (e.g., flag order if billing country differs from IP country) is trivial. However, FraudLabs Pro relies on global blacklists, IP risk intelligence, and cross-merchant chargeback data that you cannot replicate in a standalone application.
you can rebuild
- Custom rule builder engine (e.g. IF order > $500 AND shipping != billing THEN flag)
- Manual order review status dashboard and approval queues
- Velocity checking per customer email or IP address
- Disposable email domain blacklisting using static open-source lists
- Automated order hold status updates via e-commerce platform webhooks
what you lose
- Access to a global cross-merchant blacklist of malicious buyers and emails
- Proprietary real-time IP reputation, proxy, VPN, and TOR exit node detection data
- Cross-site device fingerprinting telemetry
- Phone number and carrier risk scoring lookups
- Historical global chargeback statistics associated with individual buyer attributes
real moats
- Proprietary global dataset of reported fraud cases across thousands of online stores
- Network effects: every merchant reporting a chargeback strengthens protection for all other users
- Deep integration with commercial IP intelligence databases (such as IP2Location)

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
