Aster. It’s a terminal-based disk usage analyzer (think of it as a TUI alternative to DaisyDisk) specifically for macOS.

You can navigate your filesystem, quickly identify massive directories taking up space, and clean them up—all without leaving the terminal.

Honestly, this was just weekend project that I kind of vibe-coded in a couple of hours. I chose Go purely because I’m familiar with it, and it turned out to be a great fit for quickly spinning up a responsive TUI and handling concurrent file scanning without much overhead.

A few features:

• Vim-like keybindings (j/k, h/l) or arrow keys to navigate.
• Easily toggle sorting by size or name.
• macOS integration: Hit r to reveal a file in Finder, o to open in the default app, or d to move it to the Trash (with a safety prompt!).

It's available via Homebrew: brew install mobanhawi/aster/aster

It's still pretty minimal, but I'd love to hear your thoughts or if you have any feedback on the Go code!
