Our review
Pros	Free plan covers Kubernetes, AWS, Azure, GCP, VMware, and bare metal Blast-radius limits, approval gates, probes, and scheduled experiments CI/CD integration plus prebuilt faults and experiment templates	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	Paid-plan pricing requires contacting Harness Free Plan includes community support rather than standard or premier support Chaos infrastructure is deployed in the target Kubernetes environment	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
