WebClass is a free, open-source, video-conferencing platform offered by the URAN Association (User Association of Ukrainian Research and Academic Network) to Ukrainian researchers and educators for online lectures, meetings, and conferences. It is built on the BigBlueButton software and provides interactive features like a whiteboard, pointer, participant grouping, and the ability to share presentations, though it requires more technical resources and skills from organizers compared to other URAN tools like eduMEET.
