A vim-keybinded TUI for exploring tabular data from the command line. Browse, filter, sort, group, and plot CSV, TSV, Parquet, JSON, and NDJSON files directly in your terminal — no spreadsheet, no notebook, no web UI required. Built in Rust on ratatui, with 9 built-in Base16 color themes.

Highlights

• Search, filter (> 500, = North, != (null)), multi-column sort and group-by, all from the keyboard
• Charts in the terminal: line, bar and histogram, several series at once
• Reads files or pipes: curl … | datasight, with the format detected for you
• A file browser for local folders, Azure Blob Storage and S3
• Save exactly what you see to CSV, or copy a cell or row to the clipboard, even over SSH
• An agent or a script in another terminal can read and drive the table you have open (datasight ctl), with a ready-made Claude Code skill (--skill)
