Zoxide

Zoxide learns which directories you visit most and lets you jump to them by typing a few letters. Type `z proj` and it takes you to `/home/you/projects` because that's where you always go. It's a smarter `cd` that remembers your habits.

MIT, Rust. One of the fastest-growing CLI tools right now. Works on every major shell: bash, zsh, fish, PowerShell, Nushell. Installs in seconds. Uses a frecency algorithm (frequency + recency) to rank directories, same concept as browser address bar autocomplete.

Fully free. No paid anything. It's a single binary. Install it, add the shell hook, and forget about it. Every developer from solo to enterprise benefits. There is zero ops burden. It stores a tiny database file in your home directory.

The catch: honestly, almost nothing. The learning curve is typing `z` instead of `cd`. If your directory names are ambiguous (three folders all starting with "app"), you'll occasionally land in the wrong one until you train it with `z` flags. But that's nitpicking. This is one of those tools where the only question is why you didn't install it sooner.
