OpenCost vs Podledger

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.

Podledger is an open-source Kubernetes cost monitoring and optimization platform. It shows real-time spending at pod, workload, and team levels through dashboards. Its AI engine examines workload patterns, resource use, and cost data, then recommends pod right-sizing, node-pool changes, and scheduling adjustments. The Autonomous tier can apply those changes automatically when configurable guardrails allow it. Podledger runs inside your Kubernetes cluster with read-only, least-privilege access and no sidecars, and installation is available through a Helm chart. Community Edition uses the Apache 2.0 license, is self-hosted, always free, and has no stated usage limits. Community supports one cloud and GitHub support. Enterprise adds managed hosting, infrastructure, security patches, automatic updates, RBAC, SSO, multi-cloud coverage for AWS, GCP, and Azure, and priority support with an SLA. Data retention is listed as 30 days. Plans include Community at free (billed Forever free) and Enterprise at usage-based pricing not listed.
