Chaos Mesh vs Chaos Monkey

Chaos Mesh is a free, open-source platform for running fault simulations in development, testing, and production environments. It runs on Kubernetes and manages experiments through Kubernetes CustomResourceDefinitions and the Kubernetes API. Fault simulations cover areas including Pods, networks, DNS, HTTP, I/O, time, stress, kernels, block devices, JVMs, physical machines, and AWS, Azure, and GCP. Schedule, Workflow, and StatusCheck resources support recurring experiments, serial or parallel workflows, and application health checks. Selectors and namespace controls help scope experiments to chosen targets. Chaos Dashboard offers a web interface and HTTP API for creating, managing, and observing experiments, with role-based access control enabled by default. Chaos Mesh is licensed under Apache License 2.0 and can be installed from its Helm repository using Helm 3. Compatibility varies by release: version 2.8 supports Kubernetes 1.30 through 1.35, while version 2.7 supports 1.26 through 1.28. Its privileged Chaos Daemon runs as a Kubernetes DaemonSet by default, though that permission can be disabled. Community support is available through CNCF Slack and GitHub Discussions.
