How KostKube Works
From zero to cost clarity in under 15 minutes. Here's exactly what happens when you sign up.
What is KostKube?
KostKube is a cloud-hosted software platform (SaaS) that helps engineering teams understand and reduce their Kubernetes infrastructure costs. You access KostKube through your web browser at app.kostkube.com — there is nothing to download or install on your computer.
The only component that runs in your environment is a small, read-only monitoring agent deployed to your Kubernetes cluster. This agent collects resource utilization metrics and sends them — encrypted — to the KostKube cloud platform, where they are processed, analyzed, and presented to you through the dashboard.
Cloud-Hosted
Dashboard lives at app.kostkube.com
Read-Only Agent
Never modifies your cluster
Fast Setup
First report in under 10 minutes
The KostKube Agent
The KostKube agent is a lightweight Kubernetes deployment that you install with a single command. It is open source — you can inspect every line of code before you deploy it. Here's what you need to know:
50MB memory footprint
Minimal impact on your cluster resources
Read-only by design
Only reads CPU, memory, and storage utilization data
TLS 1.3 encrypted transmission
All data encrypted in transit to KostKube cloud
Minimal RBAC permissions
Only the read permissions it needs — nothing more
# Install the KostKube agent to your cluster
$ kubectl apply -f https://install.kostkube.dev/agent.yaml
namespace/kostkube-system created

The agent source code is available on GitHub. You can review exactly what permissions it requests and what data it collects before deploying.
The KostKube Dashboard
The KostKube dashboard at app.kostkube.com is your command center for Kubernetes cost management. It has four primary views:
Cost Overview
Your top-level summary. Shows total cluster spend for the current period alongside a trend chart comparing this month to the previous month. Key metrics — compute cost, storage cost, network cost, and total savings identified — are displayed as prominent stat cards. You can see at a glance whether your cloud bill is heading in the right direction.
Cost Breakdown
Drill into your costs by namespace, deployment, pod, or team label. An interactive treemap visualization makes it immediately obvious which workloads are consuming the most resources. Filter by date range, sort by cost or efficiency score, and export data as CSV or PDF for internal reporting or chargeback purposes.
Recommendations
A prioritized list of specific cost-saving actions, each with an estimated dollar impact. Recommendations are ranked by potential savings so your team knows where to focus first. One click exports any recommendation to a Jira ticket, a Slack message, or an email — complete with the technical details your engineers need to act.
Settings
Manage your clusters, team members, and notification preferences. Add new clusters, configure Slack or email alert thresholds, manage user roles (Admin, Editor, Viewer), set up scheduled cost reports, and configure SSO (on Business plan and above). Your billing and subscription details are also managed here.
