Where is your AWS bill actually leaking?
Drop in a Cost Explorer export. We’ll read the service mix, flag the patterns that usually mean waste, and estimate what you could recover — in about two seconds, in your browser.
Drop your Cost Explorer export here
A CSV grouped by service, covering the last 3 months. Nothing leaves your browser.
Getting the file
Three clicks in the AWS console.
Open Cost Explorer
In the AWS console, go to Billing and Cost Management → Cost Explorer, then choose Explore costs.
Group by service, last 3 months
Set the date range to the last 3 months, granularity to Monthly, and Group by → Service. This is the default view for most accounts.
Download the CSV, drop it here
Hit Download as CSV in the top right. That file is all this tool needs — and it never leaves your machine.
What it looks for
The nine patterns that show up in almost every bill.
These are the same checks that open a real audit. The difference is that an audit then goes and looks at the resources themselves.
- ✓Compute that's sized for traffic you don't have
- ✓The “EC2 — other” bucket where EBS, NAT and transfer costs hide
- ✓Databases running availability nobody asked for
- ✓Cache and search clusters provisioned for a peak that never comes
- ✓NAT Gateways billing you hourly and per gigabyte
- ✓Log retention set to never expire
- ✓Storage with no lifecycle rules
- ✓On-demand rates on workloads that never turn off
- ✓Month-over-month jumps that mean something got left running
Questions
The ones people actually ask.
Is my billing data uploaded anywhere?
No. The file is read and analysed entirely in your browser using JavaScript — it is never uploaded, never transmitted, and never stored. You can disconnect from the internet after the page loads and the tool still works. For completeness: the site uses cookieless analytics that counts page views and records that the tool was run, but it is sent nothing from your file — not the total, not a single service, not even a rough size.
Do I have to give you my email?
No. There's no form, no gate, and no account. Use it and leave — the tool is genuinely free.
How accurate are the numbers?
They're pattern-based estimates, not measurements. The tool reads your bill, not your account, so it can tell that your ElastiCache spend looks high for your bill size, but not which node is oversized. That's what a real audit is for, and it's why every figure here is a range.
What file formats work?
The Cost Explorer CSV export is the intended input. The parser is forgiving — a plain list of lines like “EC2, 3800” works too, as does a tab-separated paste from a spreadsheet.
The teardown reads your bill. An audit reads your account.
