flyctl is a command-line utility that lets you work with Fly.io using fly commands, from creating your account to deploying your applications. It runs on your local device so you’ll want to install the version that’s appropriate for your operating system.

​
macOS

If you have the Homebrew package manager installed, flyctl can be installed by running:
If not, you can run the install script:
If you used curl to install flyctl, then you need to add the flyctl directory to your shell rc file. Check the output of the install script for the entries to copy and paste into the file. Now you can use the fly command from any directory.

​
Linux

Run the install script:

​
Windows

Run the PowerShell install script:
If you encounter an error saying the pwsh command is not found, powershell can be used instead, though we recommend installing the latest version of PowerShell.

​
Uninstall flyctl

How you remove flyctl depends on how you installed it. Homebrew (macOS): Uninstall with brew uninstall flyctl. Install script (macOS and Linux): Remove the flyctl directory (~/.fly by default), then delete the lines the install script added to your shell rc file (for example ~/.bashrc or ~/.zshrc) to put flyctl on your PATH. Windows (PowerShell): Remove the flyctl install directory (~\.fly by default) and remove its entry from your PATH.
