Multi-Database Support
Connect to PostgreSQL, MySQL, SQLite, and Firestore from one app. One familiar interface for all your databases — no context switching.
Supports PostgreSQL / MySQL / SQLite / Firestore
The database client
you deserve
A fast, native desktop client for PostgreSQL, MySQL, SQLite, and Firestore. Browse 100k+ rows instantly, export to CSV/JSON/SQL, and keep your credentials safe in the OS keychain.
"Finally, a database client that feels native and doesn't try to be everything. Queryline is fast, focused, and gets out of your way so you can just write SQL."
Built for developers / Free for macOS
Everything you need, nothing you don't
Schema Browser
See every database, table, and column at a glance. Click to preview, double-click to open — everything is one or two clicks away.
OS Keychain Security
Your passwords never touch a plain text file. Credentials are locked in your OS keychain, protected by the operating system itself.
Multi-Format Export
Export query results to CSV, JSON, or SQL INSERT statements with a single click. Perfect for sharing data or migrating between databases.
Query History
Never lose a query again. Your recent queries are automatically saved per connection, so you can always go back and rerun previous work.
Resizable Layout
Drag to resize the sidebar and result panels to your preference. The flexible layout adapts to how you work, not the other way around.
Secure Connections
Manage connections with confidence
Set up your database credentials once and they're securely stored in your OS keychain. Edit, duplicate, or test connections anytime — your passwords never touch a config file.
- View and edit connection details inline
- Passwords stored in macOS Keychain, never in plain text
- Test connections before saving to catch issues early

All credentials are stored securely in your operating system's native keychain (macOS Keychain, Windows Credential Manager, or Linux Secret Service). They are never written to plain text files.
Yes! Queryline is free to download and use. Grab the latest release from our GitHub releases page and start querying in seconds.
Queryline runs on macOS, Windows, and Linux. Current builds target macOS, with more platforms coming soon.
Yes! You can export results to CSV, JSON, or SQL INSERT statements directly from the results panel. Just click the export button after running a query.
Queryline only renders the rows you can actually see on screen, no matter how large the result set. This means you can scroll through 100,000+ rows with zero lag — it feels the same whether you have 50 rows or 500,000.
