Show HN: Duck-UI – Browser-Based SQL IDE for DuckDB (Score: 150+ in 7 hours)

Link: https://readhacker.news/s/6DRv7
Comments: https://readhacker.news/c/6DRv7

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.
Friction at every step (TOO MUCH to load a csv or even to test some sql (study)...
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:
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
Technical Details:
DuckDB compiled to WASM; query execution in-browser
OPFS-backed persistence
Apache 2.0 licensed
Runs on Chrome 88+, Firefox 79+, Safari 14+
Use Cases:
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)
GitHub: https://github.com/ibero-data/duck-ui
Live Demo: https://demo.duckui.com
Quick Start: docker run -p 5522:5522 ghcr.io/ibero-data/duck-ui:latest
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.

Ask HN: What are people doing to get off of VMware? (Score: 150+ in 10 hours)

In certain large industries it feels like there's more urgency to migrate off of VMware than there is to do genAI stuff.
Do others sense this? If so, what options do you see for folks to keep their servers but move off of VMware? Is it all RedHat?
