Atmosly Kubernetes Cost Optimization

Overview

Atmosly brings account, cluster, namespace, and service spend into a normalized dashboard across Amazon EKS, Google GKE, and Azure AKS. Team showback dashboards make it easier to connect shared cloud costs to the groups using them. Right-sizing recommendations draw on workload p95 usage over time and show estimated dollar impact, giving teams a basis for prioritizing changes rather than just identifying spend.

Telemetry depends on an existing in-cluster Prometheus instance; kube-prometheus-stack works out of the box. Teams can connect with a Helm-installed read-only agent or direct cloud integration. A connected cluster can be assessed read-only, and proposed changes go through reviewable pull requests with explicit approval. That is a sensible control for teams wary of automatic workload changes, but Prometheus is a prerequisite rather than something Atmosly replaces.

Key features

• Cost allocation and showback: Automatic allocation across accounts, clusters, namespaces, and services, plus team dashboards, helps make shared spend attributable.
• Right-sizing: p95-based recommendations with estimated dollar impact help teams weigh workload changes; pull-request application preserves an approval step.
• Commitment planning: Reserved-instance and savings-plan opportunities are ranked by monthly savings, so teams can compare potential commitments against their cost priorities.
• Budgets and waste detection: Daily budget alerts and monthly forecasts support ongoing oversight, while idle-workload and orphaned-volume detection points to potential waste.

Pricing

Atmosly uses a freemium model, with paid plans starting at $399/mo and a 30-day trial of Growth features for Team signups. Self-serve signup requires no credit card. The trial gives teams a chance to assess the broader feature set, but the lasting free option is tightly capped.

Personal is a narrow fit for one engineer on one cluster: recommendations are view-only and history lasts just seven days. Starter adds manual application and enough seats for a larger team, but caps usage at two clusters and 100 AI actions a month. Growth is the practical step up for multi-cluster operations that want automated right-sizing, more cloud accounts, and longer retention; its substantially higher price and annual billing make it harder to justify for teams that only need cost visibility. Enterprise suits organizations needing unlimited capacity and a dedicated service relationship.

Platforms

Atmosly supports Linux, self-hosted, and web platforms. The cost optimization product covers Amazon EKS, Google GKE, and Azure AKS. Its homepage says a self-hosted control plane is available on the Platform tier; cluster cost telemetry still relies on Prometheus.

Who it's for

Atmosly is best suited to Kubernetes teams with Prometheus already running, especially those operating across supported cloud platforms and needing shared cost allocation, forecasts, budget alerts, or a governed path from recommendation to change. It is less compelling for a team seeking a standalone telemetry solution, a larger free allowance, or paid entry without annual billing.

Pros and cons

• Pros: Allocation from account down to service and team showback can clarify who drives spend.
• Pros: Recommendations include estimated dollar impact and can be routed through reviewable pull requests rather than applied without approval.
• Pros: Forecasts, daily budget alerts, and commitment opportunities combine operational signals with planning tools.
• Cons: Existing in-cluster Prometheus is required, adding a prerequisite for teams without that telemetry.
• Cons: The free plan limits access to one engineer and one cluster, with view-only recommendations and seven-day history.
• Cons: Starter and Growth prices are presented with annual billing terms, which may not suit teams seeking a short-term paid commitment.

Alternatives

Consider the broader Kubernetes Cost Management Software category if you want to compare more options. KubeAdapt may suit teams wanting all features on a free allowance covering the first 100 vCPU across an account, with no credit card required. Krossboard is another freemium option. PerfectScale offers a free allowance up to 200 vCPU/month with unlimited clusters, nodes, and pods. KubeLedger is a free self-hosted option for internal use, with source code available and a restriction against selling it as a managed service. IBM Kubecost offers OpenCost with unlimited clusters and cores, or a Kubecost Free tier capped at 250 cores and $100K spend over 30 days. Flexera One IT Asset Management is a paid alternative with a free plan. OptOps is a paid option. Podledger is a freemium option.

Verdict

Choose Atmosly if your Kubernetes team already has Prometheus and wants cost allocation tied to practical, approval-controlled optimization across EKS, GKE, or AKS. Its strongest case is the combination of granular showback, actionable recommendations, and budgeting signals. Look elsewhere if a view-only single-cluster free plan is too limited, Prometheus is not part of your setup, or you need paid access without annual billing.
