Simple, Team-Friendly UI for Easy Right-Sizing

  • February 11, 2026
  • Review provided by G2

What do you like best about the product?
Cast AI has a simple UI that makes it easy for everyone on your team to understand what’s overprovisioned, along with suggested steps to take to right-size the resources. That simplicity is what I like best.
What do you dislike about the product?
The Cast AI interface sometimes suggests optimisations that, if applied blindly, may not actually be optimal. I’ve noticed this particularly with resources that are only up for short durations (1–2 minutes) per run, but run frequently (multiple times a day), such as background jobs running on spot instances.
What problems is the product solving and how is that benefiting you?
Cast AI is tackling one of the biggest challenges with cloud environments: cost optimisation. Over the past few months, we’ve saved more than 30% of our overall cloud costs by carefully validating Cast AI’s recommendations and then putting them into practice.

Optimizes ML Workloads with Clear Dashboards

  • February 11, 2026
  • Review provided by G2

What do you like best about the product?
I mainly appreciate CAST AI for its automatic cost and resource optimization. The dashboards are also pretty clear, which is nice.
What do you dislike about the product?
Sometimes we did face issues with optimization and services running out of CPU or RAM but not very frequently.
What problems is the product solving and how is that benefiting you?
I use CAST AI to optimize infrastructure for ML workloads, mainly solving on-demand services issues, suggesting spot usage, optimizing resource costs, and identifying resource wastage. I also appreciate the clear dashboards.

Efficient EKS Optimization with Stellar Support

  • February 11, 2026
  • Review provided by G2

What do you like best about the product?
I like the UI and the ease with which I can operate an EKS cluster on CAST AI. For example, rebalancing one of our largest clusters back to an optimized state took just a few clicks. Even someone who's not familiar with coding and Terraform can easily accomplish this task. I also like their support, particularly how I can interact with them via Slack. They respond extremely quickly, dive deep into any issues, and are available to jump on a call and explain things thoroughly. Additionally, Cast AI's solution comes with their own autoscaler, which allowed us to start seeing savings immediately. Their support was very helpful during the setup process, assisting us in all aspects.
What do you dislike about the product?
I think if there was an easier way to upgrade EKS clusters that would be a plus because currently after upgrading you still need to manually rebalance the nodes for all of them to get upgraded, where with EKS auto mode it's completely automated.
What problems is the product solving and how is that benefiting you?
CAST AI optimizes my EKS cluster, reducing costs with easy scaling. I love the UI and quick adjustments, even for non-coders. It saves me money immediately compared to Sedai with less effort since it includes an autoscaler.

Streamlined Infrastructure with API Integration

  • February 11, 2026
  • Review provided by G2

What do you like best about the product?
I like that CAST AI provides a single panel for visualizing and tracking performance, monitoring, and security. It gives us the visibility we need. Most functionalities are exposed via APIs, which enables us to automate security monitoring. I appreciate the easy and secure access to the dashboard and how it integrates with our internal security tools. This helps our lean team maintain compliance and security posture effectively.
What do you dislike about the product?
While having APIs is the right step, those APIs provide only high-level information. The ability to provide granular details and expose wider API endpoints with more query parameters would be great. It took us some time as the APIs didn't provide all the information we needed.
What problems is the product solving and how is that benefiting you?
CAST AI provides a single panel for visualizing and tracking performance, monitoring, and security, and offers APIs to automate security monitoring. It enables our lean team to maintain compliance and security through easy integration with internal tools.

Simplified Cost Control with CAST AI

  • February 10, 2026
  • Review provided by G2

What do you like best about the product?
I like the ease and powerful features of CAST AI. Today, we are able to have cost visibility of services and applications within our Kubernetes, which provides us with a very advanced FinOps view. The initial setup was very easy and we also had full support from our CAST AI partners here in Brazil.
What do you dislike about the product?
We are having some issues with resources from our observability tool, Datadog.
What problems is the product solving and how is that benefiting you?
We use CAST AI to control and optimize costs in Kubernetes, improving our control over cloud infrastructure costs and manual operations. It gives us cost visibility for an advanced view of FinOps.

Mostly Hands-Free, Tailored Results with Room to Grow in Cost Charts

  • February 10, 2026
  • Review provided by G2

What do you like best about the product?
It is mostly hands free and with little more work you can achieve tailored results.
What do you dislike about the product?
Not a dislike but room to improvement, I would like to have some more dimensions in cost charts and also better visibility on k8s events related to cast
What problems is the product solving and how is that benefiting you?
Aggressive autoscaling. We put heavy lift on AI processing pipelines that are heavy by design so Cast allow us to scale best suited machine from the pool for time that almost match the time required to run and it doesn't matter is it 5 or 500 instances
