All Features

Query your data directly.

Import datasets, write full SQL queries with autocomplete, and visualize results live. Cross-dataset JOINs, dry-run mode, and saved views — a local database playground, encrypted and private.

A SQL playground that stays local

PrivStack Data gives you a full SQL interface powered by DuckDB. Import CSV, JSON, or Parquet files, write queries with autocomplete, preview results before executing with dry-run mode, and JOIN across datasets. Everything runs locally and is encrypted at rest.

Your data, their servers

Spreadsheets are limited. Real databases require servers. Cloud data tools see everything you query. There's no way to run SQL against your own datasets without exposing your data.
