The SQL Workbench is built upon DuckDB WASM, Perspective.js and React.
It supports the querying remote and local data (Parquet, CSV and JSON), data visualizations and the sharing of multiple queries via URL.
There‘s also a tutorial blog post at https://tobilg.com/using-duckdb-wasm-for-in-browser-data-eng... that explains common usage patterns.
Happy to answer any questions!
