About
Sovereign cloud cost management from Frankfurt am Main
For Costfluent, digital sovereignty means facts you can check. Costfluent is a European company, seated and operated in Germany. Its core application services and primary datastores are hosted in Germany. Access to your cloud accounts is read-only, and you can revoke it at any time. Some processing happens outside Germany: encrypted backups elsewhere in the EU, the global edge network, email delivery and the cloud connectors.
Why Costfluent exists
The meeting that repeats
The bill goes up. Finance asks why. Engineering rebuilds the numbers in a spreadsheet and traces the change back to an earlier deployment. Everyone agrees to look into costs. The explanation is found, but the process has to be repeated the following month.
Companies large enough for cloud spend to matter, but not large enough to justify a full-time FinOps hire, face this problem repeatedly. Provider consoles answer provider-specific questions, while broader platforms can bring more scope and operating overhead than the team needs. That gap is what Costfluent is for.
Costfluent is an EU-native, engineering-led company built around that recurring problem. The product gives startups and small companies a focused path from provider data to explanation, ownership and regular reporting, for engineering, finance and management alike.
Principles
Three principles behind the product
Read-only access
Costfluent reads billing and cost data through access you grant in your own cloud accounts, and you can revoke it there at any time. The security page sets out what that access covers.
Calculated, not generated
Every amount is calculated from your providers' billing records, your allocation rules and your budgets, and stays traceable to the records behind it.
Focused scope
Costfluent covers the cost questions a company asks every month: what changed, who owns it, how it compares with the budget and what can be saved. It works alongside the provider consoles and your accounting system.
Product
What the product covers
Self-service from the first connection, starting on the permanent Free plan.
Cloud connections
Native connectors read billing data from AWS, Azure and Google Cloud. Kubernetes cluster costs are collected by an agent in the cluster.
Cost reports and dashboards
Saved reports and dashboards with CSV export, folders and scheduled email delivery.
Allocation and budgets
Segments and allocation rules with tag coverage, and workspace budgets tracked against actual spend.
Insights and savings
Cost anomalies and spend changes, and a savings queue that tracks each item from open to implemented.
Team access and automation
Roles for your team, and on every paid plan the Public API and the Terraform provider.
Forecasts
A forecast line on cost reports and the spend each budget is on pace for.
Budget alerts
Notifications when a budget threshold is reached.
Editorial method
How the Costfluent blog is written
Articles are published by Costfluent as a company, not under a personal byline. These rules stand behind every one of them.
Primary sources, dated
Articles rest on provider documentation, price lists and legal texts. Each ends with a sources and method section that lists them with the date they were read.
Reviewed before publication
Every article is reviewed before it is published: each factual claim, link, calculation and product statement is checked.
Only sourced figures
A figure is a price or number a provider publishes, given with its source and date. There are no illustrative bills, savings or customer numbers.
Dates that mean something
The published date is the day an article went live. An updated date appears only when its substance changes, not for a typo or a new link.
Product statements that hold
Where an article says how Costfluent helps, it names only what customers can use today and labels anything else "Planned".
