What started as a Claude Code experiment turned into a browser-native SQL workbench I now use daily.

Runs DuckDB WASM entirely in your browser. No backend, no installation, no signup.

- Query local files (CSV, Parquet, Excel) – data never leaves your machine - Handles 100M+ rows, 50GB+ files in a browser tab - Full UI: Monaco editor, schema explorer, spreadsheet-style results grid - Share SQL via URL – anyone can run your query instantly - BigQuery connector built-in (Snowflake coming)

v0.2 – actively developing. Feedback welcome.
