GizmoSQL

Run a local DuckDB/SQLite server and query it from a built-in or compatible Flight SQL client.

Our take

Useful for developers who can configure a trusted test network

Database browsing and SQL output connect local files with external clients.

Keep in mind: Benchmark/security wording is not a verified guarantee; mobile background/memory limits and driver compatibility affect service availability, and self-signed TLS needs explicit trust verification.

What you can do

  • DuckDB/SQLite and Arrow Flight SQL server
  • Built-in SQL client and data browser
  • Authentication/session logs and database export

Good for

  • Developers testing authorized non-sensitive datasets

Consider alternatives for

  • A guaranteed always-on production database

Limitations & considerations

  • Captured minimum: iOS 17.0.
  • Benchmark/security wording is not a verified guarantee; mobile background/memory limits and driver compatibility affect service availability, and self-signed TLS needs explicit trust verification.

Privacy & permissions

Databases, connection strings and JWT/passwords grant access; bind/use trusted networks, protect exports and verify certificates before sensitive data transfer.
