What about just renaming your apps? Heroku documentation on it here.
Basically, from your CLI:
heroku apps:rename stage --app superlongappname-stage
heroku apps:rename production --app superlongappname
Note that you'll probably need to use something other than a simple 'stage' or 'production', as it needs to be a unique appname (stage.heroku.com
), and I'm guessing stage and production are already taken. The point remains that you can change it to something easy.
Also, remember to update your git remotes. From your git checkout directory:
git remote rm heroku
heroku git:remote -a stage
