Show HN: Zero-config AWS CUR → interactive cost dashboard (DuckDB and Rill)

I got tired of wrestling with AWS Cost & Usage Reports, so I wrote an open-source script: point it at a folder of Parquet CUR files, run one command, and get fully interactive Rill dashboards that adapt to your tags and cost drivers.

Highlights

Clone to custom dashboards in < 5 min

Ingests many CUR exports at once—even with schema drift.

Unifies schemas. Flattens MAP-type cols like resource tags automatically.

Chooses chart types programmatically based on spend coverage, cardinality, and distibution.

Generates Rill YAML (source, metrics (including measures), canvases) so you can tweak further.
