AI Analysis

●●●BangerZero to OneBig BrainWizardry

Pyodide + SQLite in a double-clickable file beats Electron deployment hell.

Strengths

•Pyodide WASM backend running inside a ZIP file is genuinely clever architecture.
•OPC-style packaging means UI, logic, and data travel together without servers.
•Open-source runtime you can self-host instead of depending on their cloud.

Weaknesses

•Chromium-first with degraded Firefox/Safari support limits real-world adoption.
•Running arbitrary code from downloaded files raises security concerns for enterprises.

Kkr-Query2xlsx – SQL Runner to XLSX/CSV (GUI+CLI, SQLite Demo)

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.
