Accertify vs Subuno
Accertify ($5,000/mo/mo, vibe code 3/10) vs Subuno ($149/mo/mo, vibe code 6/10). Subuno is the easier one to rebuild yourself — here is what you lose either way.
Fraud

our call
Start with Subuno — highest vibe code, weakest moat.
Accertify
Building a custom rules engine with an AI assistant takes a couple of weeks, but Accertify's moat is its vast cross-merchant transaction database and hardware fingerprint network. An isolated self-hosted application has no access to global stolen card data or collective threat intelligence. You can easily build the admin workflow, but your fraud engine will be blind to external threat actors.
you can rebuild
- Manual order review queue and analyst decision workflow UI
- Custom merchant-defined risk scoring rules engine
- Basic velocity checking and IP geolocation distance verification
- Webhook triggers to hold or release risky orders in ecommerce backends
- Basic analytics dashboards tracking approved versus flagged transactions
what you lose
- Cross-merchant global transaction and stolen card threat network
- Automated chargeback representment and dispute resolution pipelines
- Hardware-level mobile and web browser device fingerprinting SDKs
- Dedicated 24/7 enterprise threat analyst team and performance SLAs
- Pre-built processor and card brand network dispute connections
real moats
- Proprietary cross-merchant fraud signals accumulated across billions of checkout events
- Direct integrations with issuing banks and chargeback networks
- Contractual performance SLAs and financial chargeback protection options

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

- Aggregated integration maintenance across a broad mesh of specialized risk APIs
