Queryline – A fast, native multi-database client for macOS

Summary: Queryline is a macOS database client supporting PostgreSQL, MySQL, SQLite, and Firestore. It enables instant browsing of over 100,000 rows, exports data to CSV, JSON, or SQL, and securely stores credentials in the OS keychain.

What it does

Queryline provides a query editor with foreign key navigation, visual filters, and analytical notebooks for cross-database queries powered by DuckDB. It offers fast performance via a Rust backend and exports code snippets in TypeScript, Zod, JSON, and SQL formats.

Who it's for

It is designed for developers and analysts working across multiple database types who want to avoid switching between separate tools.

Why it matters

Queryline reduces context switching by consolidating multiple database clients into one fast, native macOS app with secure credential management.
