Our demo totally crashed on a spreadsheet. We knew the old engine wasn't it, so we just yeeted it and rebuilt with DuckDB and WebAssembly. Basically, we put a whole analytical database inside your browser with WASM. Now parsing and queries run parallel, no cap.

It's actually wild now: 500MB CSV in ~2s. Charts on 100k+ rows are just live.

Peep it here at https://datastripes.com/

The author rebuilt their data analysis engine using DuckDB and WebAssembly, achieving significant performance improvements, and shares their experience and results.
