Open-Source real-time Anti-Money Laundering and Fraud Detection Transaction Monitoring

The open-source alternative to six- and seven-figure AML platforms — machine learning built to survive regulatory scrutiny, your data running on your own infrastructure, and a working deployment in weeks, not years.

Jube is an open source AML software and open source fraud detection software platform for real-time detection of suspicious transactions, AML case management, and fraud prevention.

Jube is fully open-source (AGPLv3) with all features available and no vendor lock-in, Jube is transparent, auditable, and extensible—deployed on your own infrastructure, in your own jurisdiction, so your data never has to leave your control, while enabling rapid adaptation to new products, workflows, regulations, or payment schemes.

  • Explainable, regulator-defensible models — Bayesian Networks and decision-tree rule output you can walk a regulator through, calibrated and validated against BASEL practice, not a black box scored on accuracy alone.
  • Hybrid detection, not rules or ML alone — thresholds, velocity, and aggregation checks alongside supervised and unsupervised machine learning, so known typologies and emerging patterns are both covered.
  • Data sovereignty, not vendor lock-in — fully open source under AGPLv3, running on your own infrastructure or your own cloud tenancy, in your own jurisdiction if that matters to you. Your data never has to leave your control, and your rules and extensions stay yours.
  • Weeks to pre-production, not years — a fixed-fee training and implementation programme reaches a working deployment in as little as a month, at a published price rather than a custom enterprise quote.
  • Rules your compliance team can actually change — a visual rule builder and coder, so a new typology doesn’t have to wait on an engineering backlog.

Adaptive Machine Learning — Exhaustive Adaptation

Jube leverages adaptive machine learning for AML and fraud detection, combining anomaly detection, supervised risk models, and continuous model training to identify both known and emerging threats, while deriving behavioral features for interpretable and actionable risk insights.

  • Unsupervised learning identifies deviations from normal customer behavior for anomaly detection
  • Supervised learning models detect known fraud and AML patterns based on historical data
  • A hybrid approach combines supervised and unsupervised methods
  • “Exhaustive Adaptation” evolves the model topology — trying different neural-network structures and variables — to find well‑generalized, computationally efficient models as data patterns change
  • Behavioral feature abstraction derives signals such as transaction volume, velocity, and geolocation to improve ML model interpretability

Real-Time Transaction Monitoring

Jube’s real-time transaction monitoring engine detects suspicious activity instantly, enabling financial institutions and fintechs to respond to fraud and AML risks as they occur. The engine combines low-latency processing, scalable architecture, and reliable storage to handle large transaction volumes efficiently.

  • Stateless, horizontally scalable architecture
  • Low-latency, in-memory processing with Redis for real-time state mutable state
  • Frequently accessed immutable state stored locally also to minimize network overhead, reduce serialization/deserialization, and increase server density, ensuring fast, scalable decisioning under high load
  • Durable storage and audit logs with PostgreSQL
  • AMQP integration (RabbitMQ) for inbound and outbound events
  • Full support for synchronous and asynchronous interfaces via HTTP, AMQP, and hybrid modes
  • Asynchronous archival of decision payloads for analytics and reporting
  • Real-time reprocessing of past data available for integration of fresh intelligence and analysis of exposure

Case Management for Compliance

Jube delivers workflow-driven AML and fraud case management with automated escalation, full audit trails, and document versioning, giving compliance teams an end-to-end solution for investigating suspicious transactions efficiently.

  • Multiple case streams (AML, fraud, compliance)
  • Workflow-driven dashboards for investigators
  • Document upload and versioning (EDD, CDD, ID verification)
  • Automatic case escalation via activation rules
  • Full audit trails for all actions

Flexible Rule Engine

Jube’s rules engine supports thresholds, velocity checks, aggregation counts, and sanctions screening, fully integrated with ML outputs for comprehensive detection.

  • Threshold-based detection
  • Velocity and aggregation checks
  • Automatically check transactions and counterparties against global sanctions lists for regulatory compliance
  • Time-to-live counters and suppression
  • Fully integrates with ML outputs for combined detection
  • Online or background preparation of velocity and other aggregations depending on data volume

Cloud-Native

Jube’s architecture is purpose-built for open source fraud detection and AML transaction monitoring. It’s fully containerized (Docker, Kubernetes), supports multi-tenancy, and is highly scalable — making it a top-tier AML and fraud detection software open source solution.

The platform preserves configuration, enabling institutions to back up, restore, and migrate rules, workflows, and ML settings. This ensures operational continuity and smooth system upgrades or deployments.

Jube supports multi-tenancy, allowing financial institutions or service providers to monitor transactions for multiple sub-clients (brands or business units) within a single deployment. Each tenant can maintain independent rules, workflows, and ML configurations.
