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.

Dimensions summary
This listing groups pricing into tiers plus usage-based charges. The Free tier gives you monitoring and cost insights at no cost. Cost Monitoring covers spending analysis across workloads, namespaces, and allocation groups. Paid tiers scale by two limits: managed clusters and managed CPU. Growth allows up to 4 clusters and up to 500 CPU. Growth 700 CPUs allows up to 5 clusters and up to 700 CPU. GrowthPro allows unlimited clusters and up to 2000 CPU. Enterprise allows unlimited clusters and unlimited CPU. CPU is charged based on usage, with an additional hourly charge per managed CPU.
Top-of-mind questions for buyers
A managed CPU is a processor unit that Cast AI actively optimizes within your clusters. Paid tiers charge based on actual CPU usage, not a fixed count. You pay an additional hourly charge per managed CPU on top of your tier. Idle or unmanaged CPUs outside the platform's scope are not metered.
Your tier sets ceilings on managed clusters and managed CPU. Within those limits, cost scales with actual managed CPU usage, billed hourly per CPU. The tier defines capacity boundaries; the hourly per-CPU charge drives the variable cost. Both apply together on the same invoice.
The Free tier gives unlimited Kubernetes monitoring and cost reduction insights at no cost. It does not include the automated optimization that paid tiers meter per managed CPU. To gain automated scaling and rightsizing across managed clusters, you move to a paid tier, which then applies the hourly per-CPU charge.
