Robusta KRR (Kubernetes Resource Recommender) is an open-source command-line tool that reads pod usage data from Prometheus and recommends CPU and memory requests and limits for Kubernetes workloads. Teams use the output to correct over-provisioned or too tightly configured workloads and so reduce cost. The tool runs locally or as a Kubernetes Job in the cluster and queries the Prometheus-compatible endpoint you configure. It covers the recommendation function of commercial Kubernetes cost-management products.
KRR is MIT-licensed and maintained by Robusta Dev Ltd., in Tel Aviv, Israel. No owner has been identified. The tool itself needs no vendor cloud, so data stays within your infrastructure. Optional features do send data onward, such as reports to Slack, exports to Azure Blob Storage or the Robusta SaaS interface; according to the privacy policy, data there is processed in the United States and Europe. The privacy policy does not mention a GDPR data processing agreement. Check your configuration before enabling these options.
