About Cast AI
Cast AI is a cost optimization platform for Kubernetes clusters and the cloud resources under them. It watches real usage and adjusts how workloads and nodes are sized.
What it does
Cast AI sets each workload's CPU and memory requests from observed usage. It packs pods onto fewer nodes, removes empty nodes and provisions new nodes from templates you define. Changes can apply automatically within the policies you set, or be sent as pull requests when they belong in code, such as Helm values or Terraform.
Key features
- Right-size CPU and memory requests from real usage
- Consolidate underused nodes and remove empty ones
- Provision nodes from templates you define
- Send Helm or Terraform changes as pull requests
- Start read-only and automate when you are ready
Who it's for
Platform and DevOps teams that run Kubernetes and spend time on capacity planning. It also helps teams whose cloud bills are high because of idle capacity, and teams running GPU and AI workloads.
Pricing and good to know
The site offers a 30-day free trial with no commitment, and no credit card is needed to start. Nothing changes in your environment until you approve it, so you can review the results before automating more of the work.
