Chaos Mesh

Chaos Mesh is an open-source Chaos Engineering toolkit for injecting controlled failures into cloud-native systems. Chaos Mesh defines fault simulations as declarative Kubernetes custom resources, allowing teams to use familiar tooling and manage chaos experiments through version control. We've found that its range of simulated failure scenarios, reproducibility and blast radius controls make it suitable for repeatable, automated testing at scale. This includes environments with GPU-dense AI infrastructure, where validating resilience can be particularly challenging but important.
