Show HN: Visual, local-first data tool

3 points by rafferty97 4 hours ago

I've spent the past two years building an app for quick, ad-hoc data manipulation because I was dissatisfied with the existing landscape of tools. I thought others might find it useful too, so I'm throwing it out into the world.

Currently, if you want to grab some CSV or JSON data and do a sequence of operations on it (filter, sort, aggregate, etc.), the path of least resistance is to open an IDE or notebook and write code. This is fine for simple tasks, but can get messy quickly and doesn't offer the same immediate visual feedback loop that something like a spreadsheet does.

I thought there ought to exist a tool that offers a similar UX to a spreadsheet but with the power of a dataframe library, so I built one.

There's no signup and it runs entirely within the browser, using Rust compiled to WebAssembly for the data processing and Solid.JS for the UI. Projects are persisted to IndexedDB and files are read directly from disk using the file system API, so nothing sensitive ever leaves your computer.

I know documentation is currently scarce, but if there's enough interest, I'm happy to work on this.

Any questions or feedback are of course welcome. I'm just curious whether anyone would actually find this tool useful.
