Cloud Billing Analysis Tools
2 free tools · no login · nothing uploaded
These are the tools that read your own billing data — and the ones where it matters most that this site has no backend at all. Your file is parsed by JavaScript in your browser. There is no server to upload it to, which you can confirm in the network tab, and that is a structural property of how the site is built rather than a promise in a privacy policy.
The bill diff answers the most-asked question in cloud cost: why did it go up? Not just which service moved, but whether the movement came from using more or from paying more. Those two have completely different owners and completely different fixes, and a per-service total cannot tell them apart. Charges with no quantity are reported as unattributable rather than being forced into one bucket or the other.
The allocation score grades how much of your spend can actually be attributed to a team, against the FinOps Foundation's own KPI. Untaggable charges are excluded rather than counted against you, and the fix list is ranked by unallocated dollars rather than by resource count — because a hundred untagged test instances matter less than one untagged production database.
Both accept AWS CUR, GCP billing exports, and FOCUS. Both work on CSV; CUR 2.0 Parquet exports need re-exporting as CSV first.

Cloud Bill Diff
Why did the bill go up? Separate the rate change from the usage change.
Drop in two billing exports — AWS CUR, GCP billing export, or FOCUS — and get a per-service and per-SKU breakdown of what moved, split into how much came from using more and how much from paying more. Reads the files in your browser; nothing is uploaded.
Cost Allocation Score
Grade your tagging against the FinOps Foundation KPI, in one file drop.
Upload a billing export and get a score out of 100 for how much of your spend can actually be attributed to a team — with untaggable charges excluded rather than counted against you, and a fix list ranked by unallocated dollars, not resource count.
Other categories
Two files compared, or every day reconciled.
Finitizer runs this analysis continuously across every account and provider, catches a rate change or a usage spike the day it happens rather than at month end, and routes each finding to the team that owns it.
