Show HN: Duck-UI – Browser-Based SQL IDE for DuckDB
Show HN: Duck-UI – Browser-Based SQL IDE for DuckDB I built Duck-UI, a web-based SQL editor that runs DuckDB entirely in your browser via WebAssembly. No backend required.<p>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.<p>Friction at every step (TOO MUCH to load a csv or even to test some sql (study)...<p>The Solution: DuckDB's WASM runtime lets us run SQL analysis client-side. Load CSV/JSON/Parquet files from disk or URL, write SQL, get results instantly. Data stays on your machine. What It Does:<p>SQL editor with autocomplete & syntax highlighting Import CSV, JSON, Parquet, Arrow (local or remote URLs) Query history, keyboard shortcuts, theme toggle Persistent storage via OPFS (data survives browser refresh) Optional: Connect to external DuckDB servers One-liner Docker deployment or Node 20+ dev server<p>Technical Details:<p>DuckDB compiled to WASM; query execution in-browser OPFS-backed persistence Apache 2.0 licensed Runs on Chrome 88+, Firefox 79+, Safari 14+<p>Use Cases:<p>Learning SQL without setting up databases Ad-hoc data exploration (CSV → SQL in seconds) Quick prototyping before shipping to production Privacy-conscious workflows (no data leaves your browser)<p>GitHub: <a href="https://github.com/ibero-data/duck-ui" rel="nofollow">https://github.com/ibero-data/duck-ui</a> Live Demo: <a href="https://demo.duckui.com" rel="nofollow">https://demo.duckui.com</a> Quick Start: docker run -p 5522:5522 ghcr.io/ibero-data/duck-ui:latest<p>Would love feedback on: (1) Use cases I'm missing (2) Performance bottlenecks you hit (3) Features that would make this your default SQL scratchpad.
