Cast AI

Cast AI does what no human DevOps engineer could realistically do, right-sizing resources based on actual workload requirements every few seconds. On average, this reduces cloud costs by 20–30%, and in less optimized environments, savings can exceed 60%.

I attended a webinar on Cast AI, and the numbers are eye-opening. For example, Wio Bank saved a staggering 70% on its cloud spend by optimizing its Kubernetes clusters.
This isn’t about guesswork—it’s about smart automation. Cast AI intelligently right-sizes nodes, automates pod placement, and leverages a mix of Spot and Reserved Instances to drive down costs.
Are you really getting the most out of your Kubernetes investment?

CAST AI automatically rightsizes workloads, removes underutilized nodes, and selects the most cost-effective instances in real time—saving up to ~ 60% on cloud bills without sacrificing performance.

CAST AI is an easy tool to onboard the Kubernetes clusters. It provides the easy dashbords to understand the CPU and RAM utilization of the Node and workloads.

What is noteworthy about their approach is how it enables DevOps operations to detect and automatically remediate security threats in real-time. While competitors’ platforms offer strong visibility and threat detection CAST AI has designed real-time remediation that automatically fixes issues before they escalate.

The easy installation, deployment and upgrade. Expert and the blazing fast support. Very intutive UI. One among the best documentation.

It was very easy for us to switch from AWS EKS Karpenter to Cast AI. […] We already during the POC, were able to reduce the Instance Costs by around 30%, so the product payed for itself.

Say goodbye to manually provisioning and managing node groups for good. Support has also been a high-point when working with Cast. In the rare occasion that we have encountered any issues they have been extraordinarily responsive and dedicate resources to assist with our problem until it is resolved, no matter the time of day or night.

Value, ease of integration, the ability to have fine-grained control over what and how we optimize

Initially i was pretty skeptical and nervous about handing over scaling of EC2 to a third party – but after it was in play we saw DRAMATIC savings wherever it was installed with our many EKS clusters, and little to no impact to services hosted inside of them.

Cast does a great job at optimizing the workload, thus reducing the cloud costs. We were pretty optimized already and it still saved us around 30-40% of the total costs(!)

We appreciate the ease of use and the efficiency gains CAST provides, allowing teams to focus on development rather than infrastructure management. We also significantly reduced cloud costs for AKS in Azure.

Cast AI enabled us to significantly reduce our EKS costs, much to the delight of our board of directors. The implementation was remarkably straightforward, and making configuration changes was effortless.

Cast.ai allows to select the cheapest instances using filters if needed and always checking if the instances are available, if not, the next cheapest option is used – Great support from the team with new features appearing constantly. Our feedback is listened :)

Keeping track of your CPU is hard, and we started from nodes, watched the drop in price! and now will adopt pods adjustments as well! thank you castAI for your white gloves integration and on going support.

I like my communication process with the team, and I love to ask for features and support help. They always come to me in less than 5 minutes for calls or messages.

The onboarding was super easy. The supporting engineers provided clear guidance and worked with our DevOps to fit our needs. Eventually, the setup provides us with substantial cost savings.

Cast Customer support to adapt to a large system like us was really great and they were eager to listen and do changes depending upon the suggestions/requirements.

Turn key implementation and save you money!

CAST AI allowed us to automate processes that balanced our cost and performance as well as freed up time for engineers, we got rid of manual maintenance.

Easy to start using and one of the best Kubernetes autoscalers in the market. CAST AI allowed us to utilize resources just perfectly what resulted in dramatically reduced AWS cost.

The main benefit is that they deliver what they promise, and actually helped us to save money as their cost analyzer is eye-opening, as well the setup is easy and fast

Ease of setup, clear policies for workload management, easy to understand potential savings. Fire and forget. Fast and knowledgeable support.

It’s much easier than the typical cloud optimizers as the team provides multiple things to optimize our costs. The ease of setup also is excellent.

A few months back, we started looking at free solutions for cost management or simply visibility since our team isn’t big yet, but we are beginning to feel the creeping up cloud bill. That’s where CAST came in clutch with their free cost analyzer.

The fact that I was able to check what I can save for free really sold me on this one. Our team was in the dark beforehand on our cloud spendings and now it’s like an eye-opening experience.

CAST AI has helped us identify cost leakage and save money on cloud.

They have managed to save more than we have agreed initially.

They delivered. The product actually works and saves you money. What I appreciated in comparison to other tools on the market is that CAST AI is easy to start using.

When you try to use the platform it is obvious that engineers had a say in its development. The console is quick to load and, apart from some minor inconsistencies, extremely easy to use.

It’s created specifically for Kubernetes and is by far the best I’ve seen to optimize container costs.
