Pacer and Fig

Fig was a terminal autocomplete app for macOS. Amazon acquired it in 2023 and shut it down in 2024, and its features moved into Amazon Q Developer CLI. Pacer starts from the Fig code that Amazon released as open source, and keeps the part most people used every day: the popover at the cursor.

The popover

It opens next to the cursor while you type and lists subcommands, options, and arguments, each with a short description.

The spec library

Pacer uses the open Fig spec library, with completions for more than 700 command-line tools. Specs you wrote for Fig work in ~/.config/pacer/specs.

The keys

Use ↑ ↓ to move, ⏎ or ⇥ to insert, and esc to close.

No account

Fig had cloud features that needed you to sign in. Pacer has no account and no server.

No AI

Pacer has no AI features. Everything it suggests comes from spec files and from commands it runs in your own shell.

Smarter local suggestions

Changed files first, branches with their last commit, ranking by what you run in each repo, a guard for risky commands, and descriptions for your repo's scripts.

One setup

Pacer supports zsh on Apple silicon Macs, in Ghostty, iTerm2, or Terminal. Fig supported more shells and terminals.

If you miss Fig's popover and use zsh in Ghostty, iTerm2, or Terminal, Pacer gives it back, and it keeps working without a company's servers. If you need bash, fish, or another terminal, Pacer does not support them yet. See the home page for features and requirements.
