Copilot CLI is GitHub’s command line tool that helps you build and manage code.
To install Copilot CLI, go to https://github.com/features/copilot/cli: and the Install Now button:
Depending on your OS and installation, you can use one of the options below:
- Cross-platform (npm) (Node.js 22+).
npm install -g @github/copilot - Windows (WinGet)
winget install GitHub.Copilot - macOS/Linux (Homebrew)
brew install --cask copilot-cli
If you run into an error like below – “Not Found – GET https://registry.npmjs.org/@github%2fcopilot-cli – Not found” it’s possible you do not have the right versions of Node or NPM. Upgrade those and try again:
Successful run should look like:
Now in PowerShell run:
copilot
This will launch the CLI:
Type /login to login to GitHub:
Note the permissions. It took a little while for the Authorize github button to become available for me, fyi:

Pressing “/” in the command bar brings a list of the available commands you can run:
For example, you can run:
/plugin
