What software tracks and reduces AWS or Azure spending?

For **AWS**, the main built-in tools are **AWS Cost Explorer**, **AWS Budgets**, **AWS Cost Anomaly Detection**, and the broader **AWS Cost Management** suite, all of which are designed to track spend and help reduce it through monitoring, forecasting, alerts, and optimization recommendations.[6][7][8]

For **Azure**, the equivalent native service is **Azure Cost Management** (often used with budgeting and alerts), which is Microsoft’s cost tracking and optimization offering. The search results you provided do not include an Azure-specific source, so that part is based on general platform knowledge rather than the cited results.

Common third-party tools that track and reduce cloud spending across AWS and sometimes Azure include **CloudZero**, **OptScale**, **Cloud Custodian**, **Komiser**, **CloudCheckr**, **Finout**, **nOps**, and **ProsperOps**.[2][4][5]
