Frequently asked questions

How do I use Database Studio?: Paste or drop your data into the workspace, adjust the options to fit your data, then copy or download the result. Multi-engine database viewer and editor — SQLite, DuckDB, PostgreSQL, MySQL, MongoDB with live CRUD.
Is my data uploaded or stored anywhere?: No. Everything runs locally in your browser — your data is never uploaded to a server. Nothing is sent to a server, so it's safe to use with private or sensitive data.
Is Database Studio free?: Yes — it's completely free with no account, no sign-up, no watermark, and no daily usage limits.
What's the maximum file size?: There's no hard limit imposed by the tool. Because processing happens in your browser, the practical ceiling is your device's available memory — most everyday files work instantly.
Do I need to install anything?: No installs and no extensions — it runs entirely in your web browser and even works offline once the page has loaded.

How it works

All processing is client-side. SQLite runs via sql.js (WASM), DuckDB via @duckdb/duckdb-wasm, and MongoDB is an in-memory document store. No data leaves your browser.

PostgreSQL and MySQL use DuckDB's dialect translation layer. The SQL you write is DuckDB with PG/MySQL syntax sugar — not a real Postgres or MySQL server.

Double-click any cell in the results table to edit it inline. Changes are committed immediately. Press Enter to save or Esc to cancel.

Keyboard shortcut: Ctrl+Enter runs the query.
