I'm building a privacy focused analytics tool, using WebAssembly and DuckDB. You can upload your files (CSV, JSON and Parquet), and interact with them as where they a SQL Server.

Your data never leaves your computer, however I do track page views and visitors using Plausible.

The next steps are to add forecasting and segmentation, as well as some data visualisation capabilities.

I would love to hear your opinion. All code for the repo is available here: https://github.com/dilovancelik/client_side_analytics

Cool project! Always love seeing more people adopting DuckDB. One question, if the goal is privacy, why add the requirement for a browser into the mix? Why should people use this tool instead of https://harlequin.sh or some other tool that won't require a browser?
