This simple node module will give you detailed pricing for all your Heroku applications in one single command and only requiring your API Token. This price is only an estimate at the given time that you run the command.

You can also export to CSV using --csv and skip inactive apps using -i. For detailed instructions run hcc -h

Example output :

npm install -g hcc
hcc --token your-heroku-token
hcc --token your-heroku-token -c output.csv

For now shared addons will be added multiple times to the total cost for the whole account.
