I deployed a **Django** app using free version of **Heroku**. Now I need to run some background task so I choose [django-background-tasks](https://pypi.python.org/pypi/django-background-tasks) . As per the documentation, I have to run `python manage.py process_tasks` command after running the project using `python manage.py runserver` . So I added **Procfile** as below   

```
worker: python manage.py process_tasks
web: gunicorn CYC_Heroku.wsgi

```

But, I couldn't scale the app cause, I'm using a free version. then, can I do the same **without paying money / without credit card** ??
