MaxMind minFraud vs Subuno

MaxMind minFraud ($150/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.

our call

Start with Subuno — highest vibe code, weakest moat.

MaxMind minFraud

MaxMind minFraud relies on decades of collected IP intelligence, continuous proxy/VPN node indexing, and shared chargeback signals across thousands of global merchants. While an AI agent can build a local rule engine for velocity checks and address matching in a day, it cannot replicate the global data network that makes minFraud effective.

you can rebuild

  • Deterministic velocity limits per customer email or shipping address
  • Local rule-based risk scoring based on billing/shipping address mismatch
  • High-risk Credit Card Issuer Identification Number (BIN/IIN) filtering
  • Custom manual review order queues and automated hold status logic
  • Blacklisting and whitelisting of specific emails, domain names, and IP subnets

what you lose

  • Continuous real-time identification of VPNs, Tor exit nodes, and residential proxies
  • Cross-merchant fraud signals that flag compromised identities reported by other stores
  • Proprietary device tracking and hardware fingerprint reputation scoring
  • Machine learning models trained on millions of historic chargeback outcomes
  • Sub-50ms API response times backed by globally distributed infrastructure

real moats

  • Proprietary IP geolocation and proxy/anonymizer database updated hourly
  • Global cross-merchant network effect (fraud seen at Store A instantly protects Store B)
  • Decades of direct chargeback feedback loops fine-tuning underlying threat models

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, MaxMind minFraud 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, MaxMind minFraud or Subuno?

Subuno at $149/mo/mo for a typical mid-market store. The gap between the two is about $12/mo a year.

What do I lose if I replace MaxMind minFraud?

Continuous real-time identification of VPNs, Tor exit nodes, and residential proxies Cross-merchant fraud signals that flag compromised identities reported by other stores Proprietary device tracking and hardware fingerprint reputation scoring

What do I lose if I replace Subuno?
