Harlequin

Terminal-based SQL IDE for querying Postgres, MySQL, SQLite, DuckDB, and more

Desktopfreeglobal

Harlequin is an open-source SQL IDE that runs entirely in the terminal, letting developers and analysts browse, edit, and run queries against Postgres, MySQL, SQLite, DuckDB, and other databases through adapter plugins. It's built for people who want a fast, keyboard-driven way to work with databases without switching to a GUI client or browser-based tool.
