Creating Apps from the CLI
Last updated June 15, 2023

The app is the fundamental unit of organization on Heroku. Each app can have its own set of provisioned add-ons.
Creating a Named App
After creating an app, you probably want to git push to deploy and add collaborators so that others can deploy changes as well.
To create a new app named example, install the Heroku CLI and run this command.
$ heroku create example
Creating ⬢ example... done
https://example.herokuapp.com/ | https://git.heroku.com/example.git
The command’s output shows that the app is available at http://example.herokuapp.com. The second URL, https://git.heroku.com/example.git, is the remote Git repository URL. By default, the heroku create command automatically adds a git remote named heroku that points to this URL.
heroku create is a shorthand alias for heroku apps:create. You can see a list of all commands with heroku help.
Typically, you only use this command on an initialized Git repository. The command creates the application and a Git remote that you can use to push your code to Heroku.
$ mkdir example
$ cd example
$ git init
$ heroku apps:create example
Creating ⬢ example... done
https://example.herokuapp.com/ | https://git.heroku.com/example.git
Git remote heroku added
Creating an App Without a Name
The app name argument is optional. If no app name is specified, a random name is generated.
$ heroku create
Creating app... done, ⬢ mystic-wind-83
Created http://mystic-wind-83.herokuapp.com/ | git@heroku.com:mystic-wind-83.git
Because Heroku app names are in a global namespace, you can expect that common names like “blog” or “wiki” are already taken. It’s often easier to start with a default name and rename the app later.
Welcome Page
After creating your new app, Heroku displays a generic welcome message to its visitors if you haven’t deployed code yet. This page is served with HTTP status code 502 to indicate that the app isn’t yet running.
