      • Introduction

      Duckling is a lightweight desktop application built on Tauri for quickly browsing parquet / csv / json file data and various databases. Beyond browsing, it ships with a SQL editor, pivot tables, column profiling, value inspection, and data export, so you can explore and analyze data without leaving the app.

      What you can do

      • Browse files and databases — open a data folder, a *.duckdb file, or a database connection.
      • Run SQL — a Monaco-based editor with schema-aware autocomplete, formatting, and EXPLAIN.
      • Analyze — pivot tables, per-column statistics, value distributions, and per-cell value inspection.
      • Export — send the current result to CSV, TSV, JSON, Parquet, or XLSX.
      • Work faster — query history, favorites, and a reconfigurable shortcut overlay.

      Project goal

      The objective of this project is not to build a fully functional database management tool, but to make it easy to quickly browse and lightly analyze many kinds of data.

      Duckling supports DuckDB and SQLite natively, with experimental (not heavily tested) support for PostgreSQL, MySQL, ClickHouse, and Doris / StarRocks. See Data Sources.
