KubeAdapt

Overview

KubeAdapt breaks cost views down by cluster, namespace, workload, pod and team, with container-level allocation and cost forecasting. That makes it useful when a cluster total is not enough to identify which workloads or teams drive spend. It supports AWS, Google Cloud, Azure, OpenShift and bare-metal Kubernetes, covering mixed estates rather than cloud-only deployments.

Key features

Installation uses a single Helm chart; the site estimates it takes about five minutes. The agent has read-only Kubernetes RBAC permissions limited to list and watch, with no ability to write, create, update or delete. KubeAdapt says it does not collect Secrets, ConfigMaps, environment variables, container logs or network traffic. Aggregated payloads are signed in the cluster and transmitted using TLS 1.3 with mutual TLS. These controls suit teams that want visibility without granting an optimizer authority to change production resources.

Rightsizing provides per-container CPU and memory recommendations as YAML for review in GitOps workflows. OOM-aware, bursty-CPU and replica-aware guardrails add operational context, but recommendations are not applied automatically: teams must decide whether and how to implement them. Smart Alerting routes budget, cost-spike and new-workload alerts to Slack, email or webhooks. The read-only REST API exposes cost, capacity and resource data and authenticates with Bearer API keys. Commitment optimization is not supported.

GCP on-demand and Spot or Preemptible pricing work without setup, but Committed Use and Sustained Use Discounts are not reflected. Teams whose GCP costs depend on those discounts should not treat the resulting view as a complete account of their effective rates. The optional network agent also has a narrow reach: it requires Linux kernel 5.10 or newer and is currently priced for AWS, with GCP and Azure unsupported.

Pricing

The free allowance is 0.00 USD per free, covering the first 100 vCPU across the account, with no credit card required, all features and email support. It is a meaningful starting point for smaller estates, but the 100-vCPU cap limits how much of a larger account can use the free allowance. Email support is offered on all accounts. A free trial is also available.

For eligible young companies, Startup pricing is 0.60 USD per month, billed flat per billable vCPU per month. Eligibility requires a company under three years old, fewer than 30 employees and under $6M raised. Standard pricing is tiered per billable vCPU per month, with the first 100 vCPU free: Standard tier 1 is 1.99 USD per month for 0–500 billable vCPU; Standard tier 2 is 1.49 USD per month for 500–2,000; Standard tier 3 is 0.99 USD per month for 2,000–5,000; and Standard tier 4 is 0.60 USD per month for 5,000+ billable vCPU. The lower per-vCPU rates apply only at larger usage bands, so smaller teams should weigh the tier 1 rate against their billable footprint; qualifying startups have the lower flat rate instead.

Platforms

KubeAdapt is available as an API, on Linux, as a self-hosted deployment and on the web. The optional network agent's Linux kernel requirement is separate from the platform's broader support for Kubernetes environments.

Who it's for

KubeAdapt is a strong fit for platform and FinOps teams that need cost allocation at container granularity, work across cloud and on-premises Kubernetes, and prefer to review recommendations before changing workloads. It is less suitable when automatic remediation or commitment optimization is a requirement, or when accurate GCP cost views must include Committed Use and Sustained Use Discounts.

Pros and cons

• Pros: Cost views reach from cluster to team and pod, with container-level allocation and forecasting to support workload-level investigation.
• Pros: Read-only permissions, guarded YAML recommendations and no automatic cluster changes preserve operator control and fit GitOps review.
• Pros: The first 100 vCPU are free, all features and email support are included, and the free allowance requires no credit card.
• Cons: GCP Committed Use and Sustained Use Discounts are not reflected, which can skew cost interpretation for teams using those discounts.
• Cons: Network intelligence is AWS-priced only and requires Linux kernel 5.10 or newer; GCP and Azure are not yet supported.
• Cons: Rightsizing remains advisory, and commitment optimization is unavailable, leaving implementation and commitment strategy to other processes.

Alternatives

Kubernetes Cost Management Software is the broader category to consult when comparing options. Consider Krossboard as another freemium option with API, self-hosted and web platforms. PerfectScale is worth comparing if its free allowance of up to 200 vCPU per month, with unlimited clusters, nodes and pods, better matches your footprint. Choose Varcio Kubernetes Cost Management if a paid entry plan with a 30-day spend history is preferable and Kubernetes detectors are not needed on its Explorer plan.

Randoli Cost Management for Kubernetes is an alternative to evaluate for enterprise requirements such as volume commitments, custom Entra ID or Okta group mapping, audit logs, dedicated support and on-premises or air-gapped deployment. nOps is another option if you want to compare paid cost visibility and allocation or autonomous rate optimization. Atmosly Kubernetes Cost Optimization may suit a small deployment that fits its free plan limits of one cluster, one cloud account, one seat, one project, two environments and 10 applications. Flexera One IT Asset Management is a paid alternative to consider for IT asset management. IBM Kubecost is another freemium Kubernetes cost-monitoring option, including its OpenCost and Kubecost Free offerings.

Verdict

Choose KubeAdapt if your team needs detailed Kubernetes cost allocation and guarded rightsizing recommendations without giving software permission to alter the cluster. Its free first 100 vCPU and broad environment support make it especially practical for teams starting cost review across mixed estates. Look elsewhere if you need automatic changes, commitment optimization, or GCP cost accounting that reflects Committed Use and Sustained Use Discounts.
