Duck-UI
I built Duck-UI, a web-based SQL editor that runs DuckDB entirely in your browser via WebAssembly. No backend required. The Problem: Every time I needed to query csv, parquet, or even to play with SQL, I had to either: (a) spin up a Jupyter notebook (b) use the CLI (c) upload to a hosted service. Fr
What is Duck-UI?
Duck-UI is a web-based SQL editor that executes DuckDB queries directly in the browser using WebAssembly, eliminating the need for backend infrastructure. Users can query CSV and Parquet files, explore data, and experiment with SQL without installing software or uploading data to external services. The tool addresses a common workflow friction point: previously, working with SQL required either spinning up a Jupyter notebook, using the command line, or relying on hosted services. Duck-UI consolidates these approaches into a single, accessible interface that runs entirely locally in the browser. Key capabilities include direct querying of multiple file formats, a built-in SQL editor, and instant results without server-side dependencies. Since all processing happens client-side via WebAssembly, data never leaves the user's machine, offering both performance and privacy benefits. Duck-UI is designed for data analysts, engineers, and anyone needing quick SQL exploration without setup overhead. It's particularly useful for ad-hoc data inspection, CSV analysis, and learning SQL syntax. The project is open source, making it freely available and community-driven.
