Try it: https://app.pondpilot.io

GitHub: https://github.com/pondpilot/pondpilot

You can:

- Run fast SQL queries directly in your browser

- Explore CSV, Parquet, JSON, or .duckdb files without uploading

- Keep your data 100% local (it never leaves your device)

- Install as a PWA and work offline

- Use it read-only, with real-time updates when files change

It’s designed as a lightweight alternative to notebooks or BI tools – no setup, no cloud, just DuckDB in your browser.

Would love feedback, feature ideas, or contributions. Thanks!
