Hi, I'm Derek. This is my second Show HN about Datui. It's undergone a lot of changes since my first post in February.
This started because I wanted a nice visual debugger for Polars dataframes, while working on analysis of some aircraft engine data. What started as a tool for a quick look, eventually became a place to add all the things I usually open a notebook for when starting work on a new dataset: charting, analysis, diving into groups.
This is a single-binary terminal viewer for tabular data: local or remote. Built on Rust, Ratatui, and Polars. Directories (and bucket prefixes) can be opened as one table.
I took a lot of inspiration from VisiData, but wanted to focus on viewing and not editing (datui does support exporting) large datasets.
I also wanted it to be themeable, have mouse support, and a customizable home page that I can use as a data catalog.
