Kount vs Subuno
Kount ($1,500/mo/mo, vibe code 5/10) vs Subuno ($149/mo/mo, vibe code 6/10). Subuno is the easier one to rebuild yourself — here is what you lose either way.

- Not feasible (requires billions of cross-merchant signals)
Fraud
$149/mo/mo
- MVP
- 1 week
- Full replacement
- 6-12 months, due to third-party API integration maintenance and continuous rule optimization

our call
Start with Subuno — highest vibe code, weakest moat.
Kount
While building a risk-scoring API and rules dashboard takes days, Kount's core asset is cross-merchant signals from billions of global transactions. An isolated store running local heuristics will fail to detect distributed fraud rings and novel card-testing attacks.
you can rebuild
- Static velocity checks (e.g. >3 orders per IP per hour)
- Rule-based order holding and fulfillment pause rules
- IP geolocation and basic proxy detection API wrappers
- Custom risk-scoring admin interface for manual review
- Disposable email domain blocklists and regex matching
what you lose
- Access to Kount's Identity Trust Global Network (32B+ annual interactions)
- Advanced client-side device fingerprinting and canvas inspection
- Chargeback representment integration and financial liability guarantees
- Cross-merchant card testing detection across un-linked ecommerce stores
- Machine learning models pre-trained on global fraud outcomes
real moats
- Consortium data network linking millions of devices, emails, and card tokens
- Direct Equifax credit bureau and identity verification graph integrations
- Automated chargeback dispute pipelines with acquiring banks
open source escape hatches
- FingerprintJS BSL-1.1
- Zen Engine MIT
- MaxMind GeoIP2 Apache-2.0
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, Kount 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, Kount or Subuno?
Subuno at $149/mo/mo for a typical mid-market store. The gap between the two is about $16,212/mo a year.
