## What it is
A free Windows desktop application for viewing and querying Apache Parquet files. It supports SQL queries, metadata inspection, partitioned files, and exporting image/audio data.

## Use cases

- you want to run simple SQL against parquet without a data cluster
- you need to preview binary columns like images or audio

## When to avoid
- you need cross-platform or Linux/macOS support
- you need programmatic parquet processing in a pipeline
- you need heavy-duty analytics on very large datasets
