New Design Review: the cost of a Terraform change, on the pull request

Every dollar, traced to the team that spent it.

Cloud, Kubernetes, bare metal and AI coding agents flow into one ledger. CostOptix splits it by team, sends each spike and saving to the team that owns it, and prices infrastructure changes before they merge.

Anomalies, the day they happen

Every service, namespace and host unit is checked against its own history. Alerts go to Slack, Teams, Discord or any webhook, and to the team that owns the spend.

Cost per order, not just cost

Divide a team's spend, or any slice of it, by orders, customers or requests. Revenue can come straight from Stripe.

Ownership

Every cost has an owner. Every saving has a decision.

Teams claim spend by namespace, host, cloud tag, service, resource group or account. Shared costs like observability are split by use and managed by one team, so nothing sits unowned.

  • Spikes and savings go to the owning team's channel
  • Name the team that decides on clusters, commitments and AI plans
  • Hold or defer a saving with a reason and a revisit date. It reopens if the saving moves.

Design Review

Know the cost before you merge.

Add one step to GitHub Actions, GitLab CI or Azure Pipelines. Each Terraform plan is priced against what the resources really cost you today, not a list price, and the result lands on the pull request.

  • VMs, scale sets and node pools on AWS, Azure and Google Cloud
  • Try scenarios on a system: resize a pool, change replicas, remove a resource
  • Record the decision, then check the real bill against the estimate

Dependency maps

See what every app costs, as it runs.

The host agent maps which apps call which, with each one's daily cost. Select one to see what would lose a dependency if it stopped, and how much daily spend that carries.

Kubernetes maps are in beta.
