1.3MB WASM database beats DuckDB 5x on 10M row analytics, runs in Cloudflare Workers.
Exports straight from .sql to XLSX/CSV with sensible niceties — template-aware Excel exports, CSV profiles (delimiter/encoding/quoting/date formats), retry handling for deadlocks, and a demo SQLite so you can try it immediately. It’s not trying to be a BI stack; it’s focused on the boring but painful task of re-running queries and producing predictable spreadsheets. If you want multi-step ETL, dashboards, or semantic modeling, this isn’t it — but for quick, repeatable reports it’s pragmatic and usable out of the box.
