Lake-scale SQL, puddle-sized

Only for Mac

Free · In‑App Purchases

Mac

Drop a Parquet or CSV on the icon and every column shows its shape. Query it in SQL. Nothing to import, no server, no account. Datapuddle is a native Mac app for querying data that lives on your machine. Open a Parquet, CSV, JSON, or .duckdb file and it is a table you can query — no import step, no server, no account. Point it at a folder and query the whole folder. Results stream into a grid built to stay smooth on files far larger than memory. WRITE SQL, READ RESULTS • A SQL editor with completion that knows your tables and columns • Results in a grid that scrolls at full speed through millions of rows • Jump to any row instantly • Every column header carries an inline profile: type, null count, and the shape of the values • Click a cell to inspect the full value, however long it is SEE WHAT THE QUERY DID • A visual plan with timing for each operator, so a slow query tells you where it spent its time • Query history you can search and re-run • Cancel a running query without waiting for it to finish A FULL ENGINE, BUILT IN Powered by DuckDB, compiled into the app with 17 extensions already linked — Parquet, JSON, Iceberg, full-text search, Excel formats, Avro, ICU collation, HTTP and S3 filesystems, and more. Nothing is downloaded or installed at runtime, and nothing asks you to manage an engine. CONNECT TO MORE THAN FILES • Database files on disk • PostgreSQL and SQLite • MotherDuck, and self-hosted servers over the Quack protocol • Data in S3 and other object storage • Credentials are stored in the macOS Keychain, never in a settings file BUILT FOR THE MAC • A single app, not a browser in a window • Full keyboard control, Dark Mode, and multiple windows • Sandboxed, and it reaches only the files you open TRY IT FIRST Datapuddle is free to download and fully functional for a trial period. Keeping it is a one-time purchase — no subscription, and no account either way. NO TELEMETRY Datapuddle makes no network request you did not ask for. There is no analytics SDK, no third-party crash reporter, and no account to create. What you query stays on your machine. Crash reports reach us only through macOS itself, and only if you have turned on "Share with App Developers" in your own privacy settings. Powered by DuckDB.
