Paid plans start at $1,000/mo. There's also a free plan.
CAST AI has a free Kubernetes Cost Monitoring tier, but its paid plans start at $1,000 per month before usage. Growth and Growth PRO add $0.00694 per managed CPU per hour; Enterprise starts at $5,000 plus the same hourly rate. The tiers also have different capacity limits: Growth stops at four clusters and 500 CPUs, while PRO allows 2,000 CPUs. Treat the base price as a floor, not your bill. Custom Quote rates aren’t published.

02What the plan grid doesn't tell you
CPU charges stack on the base
Growth, Growth PRO and Enterprise list a monthly base fee, then add $0.00694 per managed CPU per hour. Your total varies with CPU usage.
Growth has hard caps
Growth is capped at four managed clusters and 500 CPUs. The pricing information doesn’t publish an overage rate.
PRO still has a CPU limit
Growth PRO allows up to 2,000 CPUs, not unlimited. Enterprise lists unlimited CPUs, but starts at $5,000 per month plus CPU charges.
Custom rates aren’t published
Custom Quote pricing is usage-based, but rates aren’t listed. The pricing page lists no annual billing option.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Teams within Growth’s caps | Growth | It covers up to four managed clusters and 500 CPUs, with a $1,000 base fee plus managed CPU-hour charges. |
| Teams needing more capacity | Growth PRO | It allows unlimited clusters and up to 2,000 CPUs, at the same $1,000 base fee and per-CPU rate as Growth. |
| Large teams with custom needs | Enterprise | It lists unlimited clusters and CPUs, but costs $5,000 per month plus CPU charges. Confirm the total with sales. |
04Is CAST AI worth the money?
CAST AI is a capable Kubernetes optimization suite, but its pricing only makes sense if the base fee and CPU charges fit your budget. The free tier offers monitoring, but excludes automation. Paid plans have a monthly floor before usage, and Growth and Growth PRO have capacity caps. Enterprise removes those listed caps, but its $5,000 base fee is a much higher starting point. Before switching, ask sales to map the functions you need to a plan and quote your expected usage.
