Fraugster vs Subuno
Fraugster ($2,500/mo/mo, vibe code 4/10) vs Subuno ($149/mo/mo, vibe code 6/10). Subuno is the easier one to rebuild yourself — here is what you lose either way.

Start with Subuno — 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

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
