InfraSim simulates infra failures without touching production. Unlike Gremlin or Chaos Monkey, InfraSim runs 150+ chaos scenarios in memory — proving your system's theoretical availability ceiling. Key features: - 5 simulation engines (Static, Dynamic, Ops, What-If, Capacity) - 3-Layer Availability Limit Model (4.00 to 6.65 nines) - AI-powered analysis with remediation recommendations - DORA compliance report generation - Terraform/Prometheus integration - Plugin system for custom scenarios

Hi everyone! I'm Yutaro, an infrastructure engineer from Tokyo. I built InfraSim because I was frustrated with chaos engineering tools that require production access. My team needed to evaluate "what happens if our DB goes down?" without actually breaking things. InfraSim takes a fundamentally different approach: pure mathematical simulation. You describe your infrastructure in YAML (or import from Terraform), and InfraSim runs 150+ failure scenarios to find your weakest points. The most unique feature is the 3-Layer Availability Limit Model — it mathematically proves your architecture's theoretical maximum availability, and that going higher would violate the laws of physics. It's completely free and open source (MIT). I'd love your feedback! Live demo: https://infrasim-demo.fly.dev/ PyPI: pip install infrasim
