Zero-Risk Infrastructure Chaos Engineering
Prove your system's availability ceiling mathematically — without touching production.
Existing chaos tools inject real faults into your infrastructure.
FaultRay uses pure mathematical simulation.
Six pillars of zero-risk chaos engineering
Network, process, resource, dependency, and latency chaos engines powered by Monte Carlo, Markov chains, and queuing theory.
From single-node failures to cascading multi-region outages. Every scenario is generated from your topology YAML.
The only tool that separates Software, Hardware, and Theoretical limits to reveal your true availability ceiling.
Claude-driven root cause analysis and actionable improvement recommendations ranked by impact and cost.
Generate audit-ready Digital Operational Resilience Act reports with evidence trails and risk assessments.
Automatically incorporate CVE data and NVD feeds to simulate vulnerability-triggered cascading failures.
FaultRay takes a fundamentally different approach
| Recommended FaultRay | Gremlin | Steadybit | AWS FIS | |
|---|---|---|---|---|
| Approach | Mathematical Simulation | Real Fault Injection | Real Fault Injection | Real Fault Injection |
| Production Risk | Zero | High | Medium | High |
| Setup Time | 5 minutes | Days | Hours | Hours |
| Scenarios | 150+ auto-generated | Manual configuration | Template-based | AWS services only |
| Availability Proof | 3-Layer Mathematical | No | No | No |
| Starting Cost | Free / OSS | $10,000+/yr | $5,000+/yr | Pay per use |
The only tool that proves your availability ceiling
Mathematical upper bound assuming perfect software and ideal hardware
Constrained by physical components: disk MTBF, network gear, power systems
Your actual ceiling: deploy pipelines, config errors, dependency failures
Most teams chase hardware nines while their software layer caps availability at 4 nines. FaultRay reveals exactly where your bottleneck lives so you invest in the right layer.
