Effortless Cost Optimization with CAST AI
What do you like best about the product?
I like using CAST AI for optimizing our Kubernetes clusters, particularly the right sizing of nodes by using spot instances and rebalancing nodes to fit our workloads. I appreciate the flexibility of automating the rebalance or hibernate processes. The service provides valuable recommendations on cost reduction, which is a big plus. The support from the CAST AI team during setup was also great, making the process comfortable.
What do you dislike about the product?
Nothing for now
What problems is the product solving and how is that benefiting you?
I use CAST AI to optimize our Kubernetes clusters, reducing costs by optimizing nodes, and providing recommendations. It right-sizes nodes with spot instances and rebalances them for workload accommodation. The automation of rebalancing and hibernation adds flexibility.
Notable Simplicity and Integration, Documentation Could Be Improved
What do you like best about the product?
I like the simplicity of use of the dedicated CAST AI web portal and the integration with Kubernetes. I find it valuable because it helps me keep my cloud infrastructure costs under control and allows for detailed monitoring.
What do you dislike about the product?
The configuration part could be described better and documented better.
What problems is the product solving and how is that benefiting you?
Using CAST AI, I control the costs of the k8s infrastructure by monitoring the resources actually used and avoiding waste, allowing for more efficient financial management.
Cost-Effective Scaling with Optimized Performance
What do you like best about the product?
I like CAST AI for its workload autoscaler and optimized performance. It handles scaling and spot instances very well, especially with great bin packing to reduce costs and the capability to manage spot instance interruptions effectively. The initial setup is also straightforward, just requiring a command from the CLI.
What do you dislike about the product?
I think the pricing of CAST AI could be improved.
What problems is the product solving and how is that benefiting you?
CAST AI does great bin packing to reduce costs and handles spot instance interruptions. I primarily use it for scaling and spot instances.
CAST AI Automates Kubernetes Optimization with Measurable Cost Savings
What do you like best about the product?
CAST AI is most helpful because it automates Kubernetes optimization at scale, and the upside is measurable cost savings, improved resource efficiency, and reduced operational overhead.
What do you dislike about the product?
the downsides aren’t about capability — CAST AI does what it’s designed to do well — but around transparency, scope expectations, and fit. It works best when clusters are large, workloads are variable, and teams are comfortable embracing automation.
What problems is the product solving and how is that benefiting you?
Castai solves:
Inefficient resource allocation, Manual scaling complexity, Spot instance, risk management, Cloud cost unpredictability.
And the benefit has been:
Lower infrastructure costs
Better workload stability
Less operational overhead
More time for the team to focus on platform improvements rather than infrastructure tuning

Cuts Costs and Automates Infrastructure Provisioning
What do you like best about the product?
It helps reducing costs and automating infrastructure provisioning.
What do you dislike about the product?
Sometimes, when I contact support, their responses tend to contradict each other or conflict with the documentation. For example, the way to introduce vpa and hpa at the the same time
What problems is the product solving and how is that benefiting you?
select the correct CPU and memory configurations, and add more triggers for our autoscalers.
Efficient Cost Optimizer with Smart Scaling
What do you like best about the product?
I like CAST AI because there's almost no manual effort involved, and it offers intelligent scaling. The automation is reliable and handles workloads without breaking, which I find really valuable. It effectively right-sizes and scales when needed, optimizing costs and node management.
What do you dislike about the product?
The UI navigation makes the experience slow. I think simplifying the sidebar and improving visibility would be helpful.
What problems is the product solving and how is that benefiting you?
I use CAST AI to cut Kubernetes costs and automate node scaling. It optimizes costs, solves scaling, and node management issues. It requires almost no manual effort with intelligent scaling and reliable automation that right-sizes and scales when needed.
Effortless Kubernetes Cost Optimization
What do you like best about the product?
I like the hands-off nature of CAST AI and the ability it gives developers to focus on more important work instead of tuning workload settings. It's also fairly simple to deploy.
What do you dislike about the product?
Some odd workloads with unusual resource consumption patterns require manual tuning, i.e. burst on startup, etc.
What problems is the product solving and how is that benefiting you?
I use CAST AI for cost optimization and to relieve the pain of manually configuring infrastructure scaling and application requests. I love its hands-off nature, allowing developers to focus on more important work instead of tuning workload settings.
Cost Optimization
What do you like best about the product?
Cast AI gives us the ability to take the back seat in cost optimization and allow the pod rebalancer to adjust nodes and node types to optimize our workloads for performance and cost.
What do you dislike about the product?
At times it can be hard to understand different changes that it makes and troubleshoot issues surrounding node rebalances.
What problems is the product solving and how is that benefiting you?
Cost engineering. Before CastAI our workloads were around 80% over provisioned. With CastAI, we were able to get that number to a much lower amount. It essentially unlocks free money in our budget.
Automatic Scaling That Saves Time
What do you like best about the product?
The time saved scaling workloads automatically!
What do you dislike about the product?
In the past we had problems with their automatic recommendations getting applied multiple times. This is not happening now, they've improved their algorithms!
What problems is the product solving and how is that benefiting you?
We have cases where rapid resource scaling is necessary. Cast AI helps with it, giving more headroom to workloads that need short-time resouce bursts.
Turnkey FinOps Automation with Highly Responsive Support
What do you like best about the product?
Turnkey finops automation. Very skilled and highly responsive support team.
What do you dislike about the product?
Limited fine grained auth model in the administrative UI
What problems is the product solving and how is that benefiting you?
CastAI helps fighting over provisioning of cloud infrastructure, often caused by lack of awareness or knowledge in development teams. With CastAI automation we do not need to train all these teams but can optimize automatically.
