See CostMon in action
No sign-up required. Click through the sample dashboard below, or drop in your own AWS Cost Explorer export and watch it redraw with your own numbers, parsed entirely in this page and never uploaded. This browser tab keeps the file, so it carries over to the AWS Bill Analyzer, and it clears when you close the tab.
An AWS Cost Explorer export works best, parsed entirely in your browser
Nothing you drop in is uploaded. Parsing and analysis run entirely in this page's JavaScript. This browser tab keeps the file, so it carries over to the AWS Bill Analyzer for the full line-item report on the same file. Closing the tab deletes it, and so does "Clear my file" below.
One normalized total for every provider — the number finance and engineering both trust.
This shows one AWS export on its own. See what the same dashboard looks like once your AI and SaaS bills land in it too.

Daily spend on the Claude API is running 23% above its 30-day average — worth a look before the next invoice lands.
3 EC2 instances have averaged under 5% CPU for the last 14 days.
Two RDS instances are sized for peak load that hasn't occurred in 60 days.
4 Datadog seats haven't logged in for over 30 days.
The sample "Alerts & savings" tab above is illustrative; drop in your own file and it runs CostMon's AWS Bill Analyzer rules on your numbers instead. For the anomaly detection CostMon's connected product actually alerts on, see how that triple-gate logic decides, running live in your browser.
A bill read by hand goes stale tomorrow.
Reading one export line by line takes real work. CostMon reads the next one for you, every day, for every provider you connect.
