yazi

Yazi is a terminal file manager written in Rust — vim-style keys, and a preview of whatever the cursor is sitting on, driven by async I/O so nothing blocks while it reads a directory.

Move with the arrow keys or j and k, step into a directory with l and back out with h, and watch the right-hand pane preview each file as you go. The VM is private to your browser tab; nothing you type leaves it.
