Just built something wild: a privacy-first analytics engine that runs 100% inside your browser.
Quacklytics — powered by DuckDB WASM + Next.js
No servers. No API calls. No telemetry.
Your CSVs stay local — but you can still query, visualize, and explore your data with SQL and charts.
Try it out here: https://quacklytics.avikmukherjee.me/
Really hoping to get loads of feedback.
