#What is QuackDB?

QuackDB, is an open-source in-browser SQL editor developed by Matthew Fainman (mattf96s) for iterating on DuckDB queries and visualizing results. Built with Remix (a JavaScript framework), TypeScript, Tailwind CSS, and DuckDB’s WebAssembly (WASM) library, it allows users to run SQL queries on various file formats (.csv, .json, .parquet, .sqlite, .duckdb, .arrow) directly in the browser. Leveraging Chrome’s Origin Private File System (OPFS) for persistent storage, it prioritizes privacy with no screen recordings or client-side error monitoring, only using Vercel Analytics. QuackDB is ideal for developers and data analysts experimenting with DuckDB and the Filesystem Access API, with plans for NSQL natural language queries and UI improvements. It’s MIT-licensed and open to contributions via GitHub.
