Duck-UI is a web-based interface for interacting with DuckDB with a SQL editor, data import/export, data explorer, query history, theme toggle and keyboard shortcuts.

Open-source, 100% client-side data exploration tool that enables users to analyze local and remote data using SQL. Zero-copy direct access to local datasets sets PondPilot apart from similar tools. It runs entirely in the browser—no servers, no cloud uploads, and no setup required.

Open-source in-browser DuckDB SQL playground and editor.

Open-source visual SQL workbench to query local files (CSV/Excel/Parquet/JSON) and remote databases (MySQL/PostgreSQL) in one cross-source JOIN, plus AI text-to-SQL. Browser demo runs on DuckDB-Wasm; the full version self-hosts via Docker.
