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
