Git Cloning Existing Heroku Applications
Last updated March 09, 2022
A Heroku app’s Git repository is intended for deployment purposes only. Cloning from this repository is not officially supported as a feature and should be attempted only as a last resort. Do not use this repository as your app’s canonical “origin” repository. Instead, use your own Git server or a version control service such as GitHub.
If necessary, you might be able to clone your app’s source from its Heroku Git repository using the heroku git:clone command:
$ heroku git:clone -a myapp
Replace myapp with the name of your app.
This command creates a copy of the Heroku-hosted repository that contains your app’s source and complete repository history. It also includes a heroku Git remote to simplify future pushes.
