CAST AI pricing: the quick answer
CAST AI starts free. The Free plan gives you unlimited Kubernetes cost monitoring, optimization insights, and resource management at no cost. The Growth plan runs $1,000 per month plus a per-CPU fee and turns on the automation that actually cuts spend: workload and infrastructure optimization, automated instance selection, bin packing, rightsizing, and spot management. Enterprise is custom-quoted for multi-cloud automation. The per-CPU add-on on Growth is the part to watch, because a large cluster multiplies it quickly, so the $1,000 base is a floor rather than the whole bill.

CAST AI Hidden Costs & Pitfalls
The Free tier costs nothing and the Growth tier has a low-looking base. What moves the Growth bill is the per-CPU charge stacked on top of it.

Positioning
CAST AI is low-risk to try because the visibility layer is free. The Free plan gives unlimited Kubernetes cost monitoring, insights, and resource management at no cost. The money starts at Growth: $1,000/mo plus $5 per CPU per month, which turns on the automation that actually reduces spend, bin packing, automated instance selection, spot management, and rightsizing. Enterprise is custom-quoted for multi-cloud. For a heavily Kubernetes shop, the automated savings can outrun the fee, but only once you model the per-CPU add-on honestly.
Cost drivers
- 1The per-CPU charge is the real driver. At $5/CPU/mo on top of the $1,000 base, a 200-CPU cluster doubles the bill and a 500-CPU estate pushes it past $3,500, so the base understates cost on any sizable footprint.
- 2Savings live behind the paywall. Free only recommends; the features that cut spend require Growth, so the tool costs money before it saves any.
- 3Multi-cloud is Enterprise-only. Cross-cloud automation is custom-quoted with no public figure.
Watch-outs
The automation is aggressive by design, and a few users flag reliability trade-offs when cost-cutting is pushed hard, particularly around spot interruptions and node provisioning.
Strengths
- Automation that acts on the waste rather than only flagging it
- Customer reports of 50 to 60% Kubernetes cost reduction
- Free visibility tier makes the initial evaluation genuinely no-cost
Editor’s take
Start on Free to see the waste at no cost, then move to Growth once your CPU count is large enough that the automated savings clear the $1,000 base plus $5 per CPU. If you want predictable, fixed-rate cost reporting instead of a per-CPU automation fee, Kubecost offers a free starting tier for basic Kubernetes cost visibility.
