Pick Tovin.io if

You need to answer 'who owns this bill?' across multiple clouds before — or alongside — optimization.

Pick CAST AI if

Your job is to actively reshape Kubernetes node pools and instance types to capture spot and bin-packing savings.

What mattersTovin.ioCAST AI
Job to be done Allocation, visibility, anomaly, project ledger· Active Kubernetes optimization and node automation
Access required Read-only billing credentials· Cluster write access, node controller
Cloud coverage AWS, GCP, DigitalOcean (Droplets, App Platform, K8s, Spaces)· Kubernetes on AWS/GCP/Azure
Pricing model Flat monthly: Free / $49 / $149· Percentage of realized savings, plus paid SKUs
Risk profile Cannot change infrastructure· Reshapes node pools and instance types automatically
Best paired with CAST AI or Karpenter for the optimization layer· A separate allocation tool for non-K8s spend
Pricing

CAST AI's commercial model captures a share of realized Kubernetes savings. Tovin.io is flat monthly per tracked-spend band.

Allocation before optimization

Optimizing infrastructure before you know who owns the workload makes the savings story untellable — you can't credit the right team, and you can't tell whether the optimization regressed an important customer. Tovin.io is the allocation half of that pair; CAST AI is one good answer for the optimization half.

What CAST AI does not cover

CAST AI is Kubernetes-only and AWS/GCP/Azure-only. DigitalOcean Droplets, App Platform, Spaces, and managed databases are out of scope. Tovin.io covers DigitalOcean as a first-class cloud and includes everything on the bill, not just compute.

Frequently asked

Are Tovin.io and CAST AI competitors or complements?

Mostly complements. CAST AI changes Kubernetes infrastructure to lower the bill. Tovin.io tells you which project, customer, or environment owns whatever bill remains.

Does CAST AI cover DigitalOcean?

No. CAST AI focuses on Kubernetes clusters on AWS, GCP, and Azure. Tovin.io covers DigitalOcean Droplets, Spaces, App Platform, and DOKS.

Why pick Tovin.io first?

Because allocation should precede optimization — you cannot evaluate a savings claim if you do not know which team owns the workload being optimized.

Is the percentage-of-savings model good for small teams?

It can be expensive in absolute dollars once optimization works. Tovin.io's flat price means the spend-visibility layer cost does not scale with your bill.
