SQL Workbench Embedded

What it does

SQL Workbench Embedded is a lightweight JavaScript library that transforms static SQL code blocks into interactive, browser-based SQL execution environments using DuckDB WASM. No backend required. It can also run queries on remote data, such as CSVs, JSONs or Parquet files. All DuckDB extensions that are WASM-compatible can be used as well! In case you want the full SQL Workbench experience, just click on the icon and execute your query there!

  Open-source, browser-local data exploration using DuckDB-WASM and PRQL2024 · github.com · ▲227

  Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…
