our call
Start with Ravelin — highest vibe code, weakest moat.
Ravelin
While you can easily build a basic heuristic rule engine with AI, you cannot replicate Ravelin's core value: cross-merchant network intelligence and trained machine learning models. Without shared fraud signals and historic chargeback ground truth, a self-built system will either bleed money to bad actors or block real sales.
you can rebuild
- Static rule-based order evaluation engine
- Manual order review dashboard and queue management
- Basic velocity checks (e.g., requests per IP or email)
- Simple email domain and IP geolocation lookups
- Basic webhook notifications for suspicious orders
what you lose
- Global consortium network signals identifying known fraud actors across merchants
- Client-side JavaScript and mobile SDK device fingerprinting and behavioral telemetry
- Automated machine learning models trained on historical chargeback feedback loops
- Dynamic 3D Secure (3DS2) exemption routing to optimize checkout conversion rates
- Dedicated graph visualization engine for linked accounts and fraud rings
real moats
- Global network effect: signals from one merchant immediately protect all other network merchants
- Proprietary training dataset derived from millions of verified chargeback ground truth labels
- Sub-100ms real-time evaluation infrastructure integrated directly into payment pipelines
open source escape hatches
- Apache PredictionIO Apache-2.0
- PostHog MIT
- Neo4j Community Edition GPL-3.0
Riskified
Riskified is not a software company; it is a financial guarantor that uses AI to price risk. Building the transaction classification model takes days, but taking on the financial liability of millions in chargebacks requires a balance sheet, not a script.
you can rebuild
- Browser fingerprinting and device velocity tracking script.
- Rule-based fraud evaluation engine (e.g. shipping/billing country mismatch).
- Shopify fulfillment hold integration based on risk thresholds.
- Order review dashboard for manual fraud analysts.
- Automated representment documentation compiler for payment processors.
what you lose
- 100% financial reimbursement for fraudulent chargebacks approved by the engine.
- Global merchant network graph covering tens of millions of cross-store identities.
- Direct relationships with major acquiring banks for payment routing exemptions.
- Turnkey liability transfer—store operations teams don't handle fraud disputes.
- Zero-friction dynamic checkout escalation protocols (Adaptive Checkout).
real moats
- Balance sheet capitalization to underwrite chargeback losses at enterprise scale.
- Cross-merchant global behavioral network data accumulated over a decade.
- Contractual risk-transfer agreement with enterprise merchants shift balance sheet liability.
open source escape hatches
- FraudLabs / open rules engines (Drools) Apache-2.0
- Feedzai alternatives — River BSD-3

Questions people ask
Which is easier to rebuild with AI, Ravelin or Riskified?
Ravelin. It scores 3/10 on vibe code with a moat of 8/10, so an AI-assisted MVP takes about 2 weeks and a full replacement about 12-24 months, due to the need for continuous ML training, global consortium data, and fraud feedback loops.
Which one costs less, Ravelin or Riskified?
Ravelin at $2,500/mo/mo for a typical mid-market store. The gap between the two is about usage-based a year.
What do I lose if I replace Ravelin?
Global consortium network signals identifying known fraud actors across merchants Client-side JavaScript and mobile SDK device fingerprinting and behavioral telemetry Automated machine learning models trained on historical chargeback feedback loops
What do I lose if I replace Riskified?
100% financial reimbursement for fraudulent chargebacks approved by the engine. Global merchant network graph covering tens of millions of cross-store identities. Direct relationships with major acquiring banks for payment routing exemptions.
