About Pacer

Pacer is a terminal autocomplete popover for zsh. While you type in Ghostty, iTerm2, or Terminal, it opens next to your cursor and lists subcommands, options, branches, files, and scripts, with a short description of each.

Fig showed how useful a popover in the terminal can be, and then it shut down. Its code lives on as open source. Pacer takes that code, keeps the popover and the spec library, and removes everything that needed an account, a server, or AI.

One setup

Apple silicon macOS and zsh, in Ghostty, iTerm2, or Terminal. Doing one setup well beats doing many badly.

Local only

No AI, no account, no telemetry. Every feature works from data on your Mac.

Fast

The popover must update within about 100 ms of a keystroke. pacer stats measures it on your Mac.

Invisible when idle

Your shell behaves the same with Pacer as without it.

Pacer is in development and is not ready for users yet. The home page lists what works today and what is planned.

Pacer is made by Off Leash Labs.
