Our review
Pros	Supports Kubernetes, AWS, Azure, and Google Cloud experiments Includes safeguards, controls, rollbacks, and steady-state hypotheses Offers 300+ actions and probes plus custom extensions	Controlled experiments with dry runs, blast-radius limits, and a kill switch Growth adds remediation, game-day orchestration, SLOs, and error budgets Managed SaaS and private-cloud Kubernetes Operator deployment options
Cons	The standalone interface is a command-line toolkit Scheduling uses Kubernetes CronJobs or external automation Custom extensions require Python, HTTP, or process providers	Starter is limited to core fault types and basic resilience scoring The published integration surface centers on a REST API Its Kubernetes-centered approach may not suit non-Kubernetes environments
Our verdict	Chaos Toolkit is an open-source, Python-based toolkit for developers defining and running chaos engineering experiments. Experiments are written in JSON or YAML and executed through a standalone command-line interface.
