nOps is an AI-driven cost-optimization platform with particular strength on Kubernetes / EKS — automated rightsizing, bin-packing, commitment management, and savings-share pricing models. Strong fit for teams running substantial container workloads on AWS who want active automation, not just recommendations.
Refine is also AWS-native — but free, read-only by default, and bundles a 380+ security-check catalog into the same dashboard. The recommendation engine, AI narrative reports, and anomaly detection cover the same cost-optimization ground, with a heavier emphasis on visibility and security than on automated write-action remediation.
Honest summary: If your AWS spend is dominated by Kubernetes and you want active commitment + bin-packing automation, nOps is purpose-built. If you want broad AWS optimization plus security findings in a free tool, Refine is the cheaper, more visibility-first option.
