our call
Start with Subuno — highest vibe code, weakest moat.
SEON
A custom rules engine and transaction dashboard take days to code, but SEON's core value lies in its proprietary OSINT lookups and cross-merchant fraud signals. Rebuilding the software UI is simple, but aggregating social data and phone carrier intelligence across millions of profiles independently is economically unviable.
you can rebuild
- Custom drag-and-drop risk scoring rules engine
- Transaction review dashboard with manual approve/reject flags
- Shopify checkout webhook handler for order hold/cancel
- Basic IP geolocation and proxy detection logic
- Custom risk score calculator and threshold triggers
what you lose
- Real-time social profile footprinting across 35+ services
- Cross-merchant global fraud reputation network
- Telco carrier lookup for disposable phone numbers
- Evasion-resistant device fingerprinting JS agent maintenance
- Zero-maintenance ML models trained on billions of transactions
real moats
- Cross-merchant fraud intelligence graph
- Proprietary OSINT scraping and reverse lookup infrastructure
- Direct carrier and identity data provider integrations

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, SEON 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, SEON or Subuno?
Subuno at $149/mo/mo for a typical mid-market store. The gap between the two is about $4,200/mo a year.
