We built a privacy-focused AWS cost analyzer that runs in the browser

After getting frustrated with complex cost analysis tools that are not easy to use or require sharing my private data reports, we built a simple tool that analyzes AWS Cost and Usage Reports entirely in your browser. We have no backend.

Success Story

One of our early users identified *$3,200 in monthly savings* just from the analysis. The tool especially performed well on spotting inefficiencies in DynamoDB tables that were suboptimally configured.

Key Points

100% Privacy - Your data never leaves your browser - all analysis happens client-side

Completely Free - Open for everyone (we accept donations if you find it useful)

No Setup Required - Just upload your Cost and Usage Report in .parquet file.

Under active development - We add new savings constantly and we keep up with all of the updates and changes in AWS.

The suggested changes are agnostic - No risky changes, no performance impacts, no application modifications needed.

We can help find savings in:

- DynamoDB optimizations

- ElastiCache migration opportunities (Valkey!)

- Unused resources detection

- CloudFront compression opportunities

- Opensearch and RDS migration opportunities
