Your data stays local

Billing data is downloaded to your machine as Parquet files. Nothing is sent to any third party. Ever.

DuckDB-powered

Analytical queries over months of billing data complete in milliseconds. Filter, drill down, and slice by any dimension.

Works offline

Once synced, your data lives on your machine. Analyze cloud costs from a plane at 10,000 meters — no Wi-Fi required.
