Frequently Asked Questions

How is this different from TablePlus or DBeaver? +
Those tools are designed to connect to databases. SQLBlitz is designed to query files directly. No server setup, no connection strings, no import process. Just open a file and write SQL.
Can I connect to PostgreSQL/MySQL/etc? +
No. SQLBlitz is intentionally focused on local file querying. For database connections, check out TablePlus, DBeaver, or Postico. SQLBlitz is for when you have files, not databases.
What's the maximum file size? +
There's no hard limit. SQLBlitz uses DuckDB which can handle files larger than your RAM by streaming data efficiently. We've tested with multi-gigabyte files containing tens of millions of rows.
Is my data sent anywhere? +
Absolutely not. SQLBlitz has zero network access. All processing happens locally on your Mac. We don't collect telemetry, analytics, or any data whatsoever. Check our privacy policy.
Is there a free trial? +
SQLBlitz is a one-time purchase of $14.99 with no subscription. The Mac App Store doesn't support trials, but you're covered by Apple's refund policy if it doesn't meet your needs.
What SQL dialect does it use? +
SQLBlitz uses DuckDB's SQL dialect, which is PostgreSQL-compatible with some extensions. If you know PostgreSQL, you'll feel right at home. Check the DuckDB SQL docs for specifics.
