Build Status Coverage Status Docs

Khan Academy's core mission is to "provide a free world-class education for anyone anywhere", and as over 60% of the world's population is without access to the internet, primarily in the developing world, providing an alternative delivery mechanism for Khan Academy content is key to fulfilling this mission.

KA Lite is a lightweight Django web app for serving core Khan Academy content (videos and exercises) from a local server, with points and progress-tracking, without needing internet connectivity.

Primary use cases include:

  • For servers/computer labs located in remote schools, which could be slowly syncing with a central server over a cell/satellite network or via USB keys.
  • In correctional facilities and other environments where providing educational materials is of value, but users cannot be given general internet access.
  • Mobile school "vans", which transport a server and multiple laptops/tablets between a number of schools (or orphanages, community centers, etc) in remote communities on a rotating basis, and syncing up with a central database (to download new content and upload analytics) when in an area with internet connectivity.

Later in 2017, Learning Equality will be launching the successor of KA Lite. It's called Kolibri and will have very similar features to KA Lite, but will also be a platform for many other educational resources besides Khan Academy's.

Because of the popularity of KA Lite, we are continuing to support deployments by providing fixes to problems that directly affect current usage. These include issues related to new browsers, operating systems etc. We are also still optimizing regarding performance issues.

If you are creating a new deployment at this very moment, feel assured that KA Lite is still alive and will be maintained for the rest of 2017, after which point we will be recommending that you migrate to Kolibri.

In the meantime, if you need new features in KA Lite, we welcome you to join the community and contribute. In other words, we (Learning Equality) encourages you (community members), to feel empowered and take responsibility for the future of KA Lite.
