Cast AI and Costory: Optimization vs Allocation

Costory is our product.

The short answer

Choose Cast AI if: you want automation for Kubernetes optimization: rightsizing, node scaling and Spot and GPU handling, with cost visibility by cluster, namespace and workload.

Choose Costory if: you want to allocate and explain cost across providers and platforms, not only Kubernetes. The two solve different problems and can run together.

Side by side

Where Cast AI is strong

Cast AI describes a Kubernetes control loop that rightsizes pods, scales and provisions nodes, and handles Spot and GPU workloads, with an approval step for fixes. That fits platform and SRE teams who want Kubernetes cost reduced by automation.

Where Costory is different

• Allocation first: Virtual Dimensions map accounts, projects, labels and tags to teams and features, even with incomplete tagging.

• Explanations, not just numbers: cost changes are shown next to deploys, incidents and usage metrics.

• Works where your team already is: Slack digests and alerts in the channel you choose (for example #finops), and Claude, Claude Code, Cursor and Grok Bot via MCP.

• Flat pricing: Copilot €250/month, Copilot Pro €1,000/month, billed annually, with a 30-day free trial and a connection in under 30 minutes.

What Costory does not do

• It does not buy Reserved Instances or Savings Plans for you.

• It does not apply automated rightsizing.

• It does not get write access to your cloud accounts (MCP actions create Costory objects only: alerts, reports, dashboards, events).

Can you use both?

Yes, and they complement each other. Cast AI acts on Kubernetes workloads; Costory allocates and explains cost across clouds and other platforms, and shows changes next to deploys. Costory does not optimize or apply automated rightsizing, and it is read-only on your cloud accounts.
