Fig makes the command line easier for individuals and more collaborative for teams.

Our most popular product is Autocomplete. As you type, Fig pops up subcommands, options, and contextually relevant arguments in your existing terminal.

⚡️ Installation

NOTE: Once it's downloaded, launch the app to set up Fig!

👋 What are "completion specs"?

A completion spec is a declarative schema that specifies the subcommands, options and args for a CLI tool. Fig uses these schemas to generate suggestions.

😎 Contribute your first spec in < 3 minutes

Use the steps below or follow our getting started guide:


  • Download Fig for macOS
  • Node and Yarn


  1. Make sure you have yarn installed, as that's the package manager used in this repo.

  2. Click here to fork this repo.

  3. Clone your forked repo and create an example spec

    # Replace `YOUR_GITHUB_USERNAME` with your own github username
    git clone fig-autocomplete
    cd fig-autocomplete
    # Add withfig/autocomplete as a remote
    git remote add upstream
    # Install packages
    yarn install
    # Create an example spec (call it "abc")
    yarn create-spec abc
    # Turn on "dev mode"
    yarn dev
  4. Now go to your terminal and type abc[space]. Your example spec will appear. 😊

Other things to know

  • Edit your spec in TypeScript in the src/ folder
  • On save, specs are compiled to the build/ folder
  • In dev mode, specs are read from the build folder, and generators run every keystroke.

🪄 Add AI to completions

You can use Fig's autocomplete for your own tools too. Here's how to create private completions:

import { ai } from "@fig/autocomplete-generators"


generators: [
    // the prompt
    prompt: "Generate a git commit message",
    // Send any relevant local context.
    message: async ({ executeShellCommand }) => {
      return executeShellCommand("git diff")
    // turn each newline into a suggestion (can specify instead a `postProcess1 function if more flexibility is required)
    splitOn: "\n",

📦 Other available package.json commands

# Typecheck all specs in the src/ folder
yarn test

# Compile typescripts specs from src/ folder to build/ folder
yarn build

# Lint and fix issues
yarn lint:fix
