Pacer and zsh-autosuggestions

zsh-autosuggestions shows one suggestion in gray after your cursor: a command from your history that starts with what you typed. Pacer opens a list next to the cursor of what can come next, such as subcommands, options, branches, and files, each with a description. They do different jobs.

Source

zsh-autosuggestions uses your history only. Pacer uses completion specs for more than 700 tools, the tools' own --help, git, and your history for ranking.

New commands

zsh-autosuggestions can only suggest what you ran before. Pacer also helps with commands you have never typed.

Choice

zsh-autosuggestions shows one suggestion. Pacer shows several, so you can compare them before you pick.

Where it runs

zsh-autosuggestions works in any terminal that runs zsh. Pacer needs Ghostty, iTerm2, or Terminal on an Apple silicon Mac.

Use zsh-autosuggestions to repeat what you already run. Use Pacer to find options, branches, and files, and to learn tools you use less often.
