What is zinit?

Zinit is a plugin manager for Zsh, the command-line shell popular on Mac and Linux systems. Its main job is to download and load plugins, which are small add-ons that extend what your shell can do: things like better auto-completion, syntax highlighting as you type, or shortcuts for common commands. You point Zinit at a plugin's GitHub address, and it handles the downloading, updating, and loading automatically. The feature Zinit highlights most is something it calls Turbo mode. This delays loading plugins until after the shell prompt first appears, which the project says makes Zsh start up 50 to 80 percent faster. That means the shell feels snappier when you open a new terminal window, even if you have many plugins installed. A benchmark page compares its startup time against other plugin managers. Beyond speed, Zinit keeps track of exactly what each plugin does when it loads: which aliases, keyboard shortcuts, functions, and PATH additions it sets up. This means you can inspect what any plugin contributed and, if needed, unload a plugin entirely without restarting your shell. You can also enable or disable individual completion suggestions from specific plugins. Zinit supports loading plugins from Oh My Zsh and Prezto, two other popular Zsh configuration systems, without requiring you to fully adopt either of those systems. It also has a concept called annexes, which are extensions to Zinit itself that can add new commands or behaviors. A growing library of pre-packaged setups called zinit-packages reduces the need to write long configuration lines by hand. Installing Zinit is a single shell command that runs an install script. After that, adding a plugin is a one-line entry in your shell configuration file. A detailed wiki covers everything from basic usage to advanced options for conditional loading, custom install hooks, and building plugins from source. The full README is longer than what was shown.
