Cloud Savings

• Free forever plan — Pump: Yes. OpenCost: Yes. Apache 2.0, self-hosted, no license fee, no trial period; requires deploying and running the Helm chart yourself.

• Commitment planner — Pump: Yes. OpenCost: No. Not offered. No commitment purchasing or selling exists in the project; it only reads billing data.

• Idle instance detection — Pump: Yes. OpenCost: No. Not offered. Flags cost data only; no cleanup action or automation is built into the tool.

• Autopilot continuous monitoring — Pump: Yes. OpenCost: No. Not offered. No anomaly detection or remediation engine is documented in the codebase.

• Rightsizing — Pump: Yes. OpenCost: No. Not offered. No sizing recommendation engine or execution path is part of the core project.

• Automatic budget alerts — Pump: Yes. OpenCost: No. Not offered. No budgeting module or shutdown trigger exists; alerting requires external tooling.

• Modernization recommendations — Pump: Yes. OpenCost: No. Not documented. No ARM/Graviton migration guidance is part of the cost allocation engine.

• Kubernetes auto-scaling — Pump: Yes. OpenCost: No. Not offered. Monitors Kubernetes cost data but does not adjust HPA or autoscaler configuration.

• Zero lock-in period — Pump: Yes. OpenCost: Yes. Distributed as a Helm chart installed directly from GitHub with no account or sales contact needed.

Cloud Visibility

• 100% virtual tagging coverage — Pump: Yes. OpenCost: No. Not offered: Cost allocation relies on built-in K8s labels and cloud provider tags.

• Single-lens global overview — Pump: Yes. OpenCost: No. Not offered: Reads AWS/Azure/GCP billing APIs per cluster but has no unified cross-cloud billing.

• Customizable reports — Pump: Yes. OpenCost: No. Not offered. No cost-per-customer, cost-per-feature, or other unit economics reporting is built in.

• Kubernetes deployment reports — Pump: Yes. OpenCost: Yes. Core function: allocates cost by cluster, node, namespace, controller, pod.

• CFO-level financial forecasting — Pump: Yes. OpenCost: No. Not offered. No forecasting or budget-tracking UI ships with the open source project.

• Top movers alerts — Pump: Yes. OpenCost: No. Not offered: no anomaly detection capability is available in OpenCost specification or codebase.

• Multi-channel notifications — Pump: Yes. OpenCost: No. Not offered. No native Slack, Jira, or ServiceNow connectors; alerting requires piping exported metrics elsewhere.

• Annotations & team tagging — Pump: Yes. OpenCost: Yes. Supports distributing shared cluster and idle costs across namespaces, evenly or by usage ratio.

• DeepScan technology — Pump: Yes. OpenCost: No. Not offered. No dollar-impact waste scoring or prioritized savings list is included.

• Multi-cloud support — Pump: Yes. OpenCost: Yes. Reads billing APIs from AWS, Azure, and GCP per cluster; no OCI support and no unified cross-cloud dashboard.

• Overcommitment insurance (Pump-Insured) — Pump: Yes. OpenCost: No. Not offered. No commitment purchases occur, so no savings guarantee or insurance product applies.

Cloud Security

• Team and product permissions — Pump: Yes. OpenCost: No. Relies on standard K8s RBAC to restrict access to self-hosted deployment; no app-level roles.

• Automatic budget alerts — Pump: Yes. OpenCost: No. Not documented. No SOC 2, ISO, or GDPR attestation is published for the open source project itself.

• Multi-channel alerts — Pump: Yes. OpenCost: No. Not offered: no policy engine for enforcing tagging, budget, or resource rules is in project.

• Dedicated support staff — Pump: Yes. OpenCost: No. Not offered: no app marketplace exists.

• Bank, med-tech and fin-tech compliance — Pump: Yes. OpenCost: No. Not documented. No built-in audit log of configuration or access changes ships with the project.
