DFNconf at the Technical University of Darmstadt
Web video conferencing tool for online meetings

Via DFNconf – the conference service in the German Research Network (DFN) – you can organise video and audio conferences on the web or on mobile devices free of charge.


Due to the increased use of the service in the current situation, capacity bottlenecks may be expected at peak times. DFN provides up-to-date information on this issue.
