Every semester at IIIT-D, we noticed instructors setting up these tools and links which made course management seem like a harder job than the course itself. We thought we could do better.
Backpack is designed to be all you need to connect with your students and manage your classroom. While being extremely simple to use - anytime, anywhere.
Backpack is possible because of tons of open-source software developed by awesome people around the world.
The whole app is written in Ruby on Rails with MySQL and Redis databases running on an Nginx server. We use Bootstrap and jQuery extensively in our frontend. We use Solr to search discussions and Sentry for error reporting.
