Datapuddle

About

A native macOS DuckDB client that shows the whole query result in a grid rather than paging. It reads DuckDB's columnar chunks directly and draws with Core Text, which keeps memory flat on very large results. The author reports about 119 fps and 2.8GB RAM on 20M rows across 30 columns from an 11GB parquet file on an M1 Max. It also shows column distributions, null percentage and distinct counts, query plan visualizations, searchable query history and editor autocompletion.
