About:
Harlequin is a terminal-based SQL client adapter that supports multiple database adapters including DuckDB, SQLite, and Postgres. It provides a rich Text User Interface (TUI) for executing queries and visualizing results, featuring autocompletion and syntax highlighting. The tool focuses on delivering a fast, keyboard-driven workflow for developers who need to interact with databases directly in the command line.

Key Features:

Multiple database adapter support (DuckDB, SQLite, Postgres, etc.)
Rich TUI with autocomplete and syntax highlighting
Keyboard-centric navigation and shortcuts
Query history and result visualization

Use Cases:

Rapidly querying and analyzing local data files (CSV, Parquet) using DuckDB
Inspecting and managing SQLite databases during development
Performing quick ad-hoc queries on remote production databases

Alternatives:

pgcli – Postgres-specific, while Harlequin is multi-adapter
dbeaver – Heavyweight GUI app vs Harlequin's lightweight terminal interface
usql – Command-line focused, but Harlequin offers a richer TUI experience
