Open Source C# FinOps Tools

azure-cost-cli is a command-line tool that simplifies cost analysis for Microsoft Azure subscriptions by retrieving, summarizing, and visualizing spending data directly from the CLI, helping cloud operators and finance teams understand where resources are generating costs. Users can run the tool against their Azure account to output cost breakdowns by service, resource group, tag, or timeframe, enabling quick identification of costly services or budget overruns without needing to navigate the Azure portal. It supports filtering and aggregation so teams can tie spend to organizational units or project initiatives, and it’s particularly useful for scripting automated cost checks in CI/CD pipelines or periodic reports. By bringing cost insights to the terminal, the tool helps engineers and managers catch inefficiencies early and make data-driven decisions about scaling, shutting down unused services, or optimizing reserved instances.
