Pricing
Free trial
Try this product free according to the free trial terms set by the vendor.
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.

Dimensions summary
This listing groups pricing into plan tiers plus usage-based add-ons. The Free plan gives you monitoring and cost insights at no charge. Cost Monitoring covers spending analysis across workloads and namespaces. Growth, Growth 700 CPUs, GrowthPro, and Enterprise are managed-optimization tiers that differ by cluster count and CPU ceiling, from a few clusters up to unlimited. All managed tiers charge based on actual CPU usage. Two usage components scale charges further: an additional hourly charge per managed CPU, and a Consumption Fee for platform use beyond base allocations.
Top-of-mind questions for buyers
You are charged based on the CPUs the platform actively manages in your clusters. Each managed tier sets a CPU ceiling, such as 500, 700, 2000, or unlimited. The additional hourly charge applies per managed CPU. Actual usage determines the charge, not the tier ceiling itself.
Charges track managed CPU usage, so reclaiming idle capacity lowers your metered CPU count. The platform rightsizes and consolidates workloads automatically, reducing the CPUs you pay for. As usage falls, the per-CPU hourly charge follows it down within your tier.
Your tier sets cluster and CPU limits. The additional hourly charge per managed CPU meters actual CPU use within that tier. The Consumption Fee adds charges when platform use goes beyond base allocations. All three apply together, with CPU usage typically driving most of the cost.

My Experience with CAST AI for Cloud Cost Monitoring
Reviewed on Sep 06, 2026
Review provided by G2
What do you like best about the product?
I liked Cast AI dashboard, it shows all clusters cost monitoring at one place. It can manage many clusters very easily and it works well without lagging.
What do you dislike about the product?
I dislike its pricing for cloud sessions which are on higher compared to other tools and there are many features which took me lot more time to understand and use.
What problems is the product solving and how is that benefiting you?
CAST AI helped me get a better view of cloud infrastructure costs and resource usage. It makes it easier to see where resources are being used and where there may be room to reduce unnecessary usage.
