In their own words
LitmusChaos
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.
Reliably
Reliably helps teams examine operational risks and incidents as part of resilience engineering. Built around an open-source chaos engineering platform based on Chaos Toolkit, it offers an experiment builder with more than 300 actions, including attacks and probes. Teams can import JSON Chaos Toolkit experiments, reuse templates, schedule runs, and review scores, freshness indicators, timelines, and dashboards. Experiments can run as GitHub Actions, through Reliably-managed execution, with the CLI, in Docker, or as Kubernetes jobs or cron jobs. Listed targets include AWS, Azure, Google Cloud, Kubernetes, Prometheus, and Spring. Pre-checks can prevent a run from starting; configured safeguards can interrupt one during execution. Environments store variables and encrypted secrets for the app, CLI, or GitHub workflows. The Free plan is free and limits teams to one member, 180 cloud execution minutes per month, a 10-minute cloud execution cap, and two weeks of data retention. Start costs £40 a month, billed monthly.
