ChaosBlade vs LitmusChaos

ChaosBlade is a free, open-source chaos engineering project comprising the ChaosBlade experiment tool and the ChaosBlade-Box platform. Its stated aim is to help enterprises address availability problems during cloud-native adoption. Experiments cover CPU, memory, network, disk, processes, kernels, and files, as well as multilingual applications and Kubernetes resources. They can run through the command-line interface, Kubernetes YAML and CRDs, HTTP server calls, or the Box interface. ChaosBlade-Box provides a shared experiment interface, automates deployment of experiment tools, and can host ChaosBlade and LitmusChaos. It uses Helm for deployment management and integrates Prometheus monitoring. Safety policies support manual stopping or automatic stopping after a configured timeout. Users can download and unpack the CLI on a host, or install the tool and platform on Kubernetes with Helm. The host installation guide lists Java and MySQL requirements; automatic probe installation also needs Ansible and expect. The project supports Kubernetes and is identified as a Cloud Native Computing Foundation sandbox project.

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.
