OpenCost vs Teevity

OpenCost is a vendor-neutral open source project for measuring and allocating Kubernetes and cloud infrastructure costs. It breaks down costs in real time to Kubernetes concepts and containers for showback, chargeback, and reporting. Allocation covers CPU, GPU, memory, load balancers, and persistent volumes, and it can monitor cloud resources outside Kubernetes. The included web UI visualizes Kubernetes allocations and related cloud costs. Its API provides real-time and historical Kubernetes cost reports using on-demand list prices and cloud provider cost and usage reports. Listed cloud providers include Alibaba, AWS, GCP, Microsoft Azure, Open Telekom Cloud, Oracle Cloud Infrastructure, OVHcloud, Scaleway, and STACKIT. Metrics and visualization integrations include Prometheus, Cortex, Thanos, Victoria Metrics, Grafana, and Grafana Cloud. OpenCost requires a Kubernetes cluster and Prometheus; Helm is recommended for full functionality. Cloud costs appear when provider billing data becomes available, usually several hours to 24 hours later, and on-demand pricing is not reconciled against billed actual costs. Cloud costs are not supported for on-premises clusters. OpenCost is free under Apache 2.0.

Teevity provides cloud usage analytics for AWS, Google Cloud, and Microsoft Azure. It brings bills from supported clouds into one dashboard and forecasts end-of-month costs. Dynamic Cost Explorer offers summary, detail, comparison, and reservations reports, while real-time classification can allocate spending to cost centers such as teams, projects, activity types, or countries. The documentation also lists global cost monitoring, cost and usage distribution, administrative automation, and financial and technical resource optimization. Integrations include Google BigQuery, Excel, Google Spreadsheet, and Dropbox. A REST API exposes features available in the web portal using JSON. Its CLI package includes a JAR and scripts for macOS, Linux, Unix, and Windows, and requires Java 8 or later. Dynamic Cost Explorer exports are currently CSV, with Time As Columns, Time As Lines, or Budget layouts. The free service includes high-level cost monitoring, a dashboard, and daily email. Paid plans listed include MSP, cloud reseller, and system integrator service from €99 a month, Enterprise Support at €399 a month, Enterprise at €999 a month, and Pro at €99,599 a month.
