Kalite, commonly referred to as KA-Lite, is an open-source offline educational platform that allows learners to access Khan Academy content without a constant internet connection. It provides a self-contained server and a web-based interface that can run on a single computer or within a local network, enabling streaming videos, completing practice exercises, and tracking student progress offline.

Origin and design: KA-Lite was developed by Learning Equality and a community of volunteers to extend Khan Academy resources to classrooms with limited or unreliable internet access. The project packages Khan Academy videos and exercises for local distribution, along with tools to create user accounts and monitor progress.

Technical notes: The KA-Lite server is typically built with Python and Django and runs on Windows, macOS, and Linux. It uses a local database to store user data and progress, and caches selected Khan Academy content for offline use. Content licensing follows the Khan Academy license framework; KA-Lite provides access to locally stored content under the terms of Khan Academy.

Legacy and status: KA-Lite's development informed the later Kolibri project, which extends offline learning capabilities and remains actively maintained by Learning Equality and contributors. KA-Lite is often described as a predecessor to Kolibri, and the KA-Lite project has been superseded by more modern offline learning solutions.
