Why FaultRay

The right way to test resilience

Every existing approach forces you to choose between real testing and keeping production safe. FaultRay breaks that trade-off.

Traditional chaos tools break production systems during testing
FaultRay simulates mathematically — zero production impact, full fidelity
No tooling exists for AI agent resilience testing
7 AI-specific failure modes covered: hallucination, token exhaustion, and more
Compliance evidence is assembled manually and takes weeks
DORA audit-ready evidence packages generated in one command

How It Works

Install. Load. Simulate.

A single CLI. No infrastructure changes. No agents running in prod. Point FaultRay at your config and get a resilience score in seconds.

$ pip install faultray
$ faultray load infrastructure.yaml
$ faultray simulate

✓ 2,847 scenarios tested in 4.2s
✓ Resilience Score: 73/100
✗ 3 critical findings — run `faultray report` for details

Features

Everything you need to ship with confidence

Purpose-built for modern infrastructure — cloud-native, AI-augmented, and compliance-sensitive.

Core

Zero-Risk Simulation

Mathematical fault modeling means no production traffic is ever touched. Test fearlessly, any time — including during business hours.

AI-Native

AI Agent Resilience

The first chaos tool to cover AI-specific failure modes: hallucination cascades, token exhaustion, tool-call loops, context poisoning, and 3 more.

Compliance

DORA Compliance

All 5 DORA pillars covered. Automatic RTS/ITS-format output. Evidence packages ready for auditors — no manual assembly required.

Model

3-Layer Availability Model

Mathematical proof of your system's availability ceiling. Know the theoretical maximum before you architect — not after you launch.

IaC

Terraform Integration

Native Terraform provider and GitHub Action. Shift resilience testing left into CI/CD. Catch failures in pull requests, not production.

Ecosystem

Scenario Marketplace

13+ curated scenario packs: finance, healthcare, e-commerce, multi-cloud, and more. Community-contributed packs coming at launch.

For Financial Institutions

DORA-compliant from day one

The EU Digital Operational Resilience Act mandates ICT risk testing across your full supply chain. FaultRay was designed with DORA in mind.

  • 52 DORA controls mapped and testable out of the box
  • RTS and ITS output formats for direct regulator submission
  • Audit-ready evidence packages generated on demand
  • Third-party ICT provider risk scenarios included
  • Continuous testing cadence with automated scheduling
