Free plan, no credit card · Oracle Cloud, AWS and Azure

Every cloud and every cluster, in one statement.

  • Oracle Cloud
  • AWS
  • Azure
  • Kubernetes
  • and much more…

Reads like your bank statement.

Every charge on its own line, on the day it happened, with a name you understand. No spreadsheets, no console for each cloud.

  • Statement

    Charges from every provider, by day, with search and filters. Export to CSV, XLSX and PDF.

  • Reconciliation

    Every cent in the statement is checked against the provider's billed total. If it doesn't match, you'll know.

  • Dashboard

    The whole month on one screen: how much, where it went and what changed. Increases show in amber, without alarm.

Real billing

Other platforms estimate. We start from the invoice.

OpenCost starts from list prices. Kubecost starts from them too and, with its billing integration, corrects them against the invoice after about 48 h. nuvem.cash starts from what your provider actually charged you, inside Kubernetes too, split by node, namespace and workload down to the last cent.

By workload

Total: R$48,230.00 = the invoice for the cluster's nodes

  • checkout-apiR$9,646.00
  • checkout-workerR$4,823.00
  • spark-jobsR$12,057.50
  • gatewayR$6,752.20
  • ingressR$2,893.80
  • grafana-stackR$4,823.00
  • IdleR$4,823.00
  • UnmonitoredR$2,411.50

Workloads plus idle plus unmonitored = the nodes' invoice. Difference: R$0.00.

Estimate, correct later or start from the invoice?

Point by point, with a source for every claim.

Cost centers

Every cost to its owner. From the first month to today.

Write a rule once and it classifies your entire history, not just what comes in from now on. When you fix something by hand, your classification wins over the rule.

  • By tag, namespace or account: the criteria your cloud already uses.
  • A new rule reclassifies your entire history, back to the first month.
  • Your manual classification always wins over the rule.
  • Iftag team = datathenData & ML
  • Ifnamespace = checkoutthenProduct
  • Ifaccount = stagingthenEngineering

Rules apply to the workspace's entire history.

Assistant and reports

Ask. It analyzes and proposes — you approve.

The Assistant reads your costs and your tags, finds what changed and suggests rules, cost centers and reports. Nothing is applied without your click.

Example conversation with the Assistant: a question about the rise in data costs in September, the analysis, and a proposal for a rule that sends the spark-jobs jobs to Data & ML, which only takes effect once approved.

Custom report

Cost per team this quarter

Ask for it in one sentence or duplicate a standard report. Save it and export it to PDF.

Secure by design

In your cloud, we only read.

In your cloud accounts, we only read cost data. In the cluster, the open-source agent only reads your resources.

  • Open source agent

    Apache-2.0, with a read-only collector in the cluster. You can audit every line of code.

  • No stored keys

    AWS via assume-role, Azure via a multi-tenant app with a certificate, and OCI via a policy. Revoke it whenever you want.

  • Cost data only

    No application logs and no data about your customers. LGPD compliant, with a named data protection officer.

More than a platform

A product with an engineering team behind it.

nuvem.cash is made by nuvem.online, an engineering house in Cloud & FinOps. Every number has someone who answers for it: you talk to the people who built the reconciliation, and the answer comes with the why.

Frequently asked questions

What's the difference between invoice cost and an estimate?
Many tools calculate cost by multiplying usage by a list price. nuvem.cash uses what the provider actually charged, line by line, and checks it against the invoice total, to the cent.
What access do you ask for in my cloud?
Read-only access to cost data: an assume-role on AWS, a multi-tenant app with a certificate on Azure and a policy on Oracle Cloud. No write credentials.
What about Kubernetes?
We split each node's billed cost by namespace and workload, with idle and unmonitored capacity shown as shares of their own. The total matches the invoice to the cent, per node and per day.
How much does it cost?
Start for free, no credit card. For larger volumes, talk to us.
Do I need to understand FinOps?
No. If you can read your bank statement, you can read nuvem.cash.
