Chaos Mesh vs LitmusChaos

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.

LitmusChaos is an open-source chaos engineering platform for finding infrastructure weaknesses through controlled tests. It is designed for developers, Kubernetes developers, and SREs, and supports Kubernetes along with cloud and network fault injection. Experiments can be declared, scheduled, browsed, and analyzed, and can run in sequence or in parallel. ChaosHub provides tested experiments that users can tune to get started. Probes let teams define and check steady-state hypotheses within chaos scenarios. Litmus exports Prometheus metrics so teams can assess impact through in-house dashboards or external visualization and APM tools. The platform can be installed on a user's own cluster, with Helm offered as an installation option, or used through hosted SaaS; its deployment model is hybrid. A Backstage plugin displays experiments, Chaos Hubs, environments, and experiment runs. The Litmus MCP Server works with Model Context Protocol clients, including Claude Desktop, to discover, run, and observe experiments, using tokens and scoped access. The project is CNCF-hosted and identifies itself as a CNCF Incubating Project. The hosted SaaS and open-source platform plans are both listed at free.
