Documentation

About CHASE
CHASE (CHAiring SoftwarE) is a web application for managing and conducting debates at Model United Nations conferences. It is designed for both chairs and participants. CHASE allows chairs to easily manage debates, while participants can follow the discussion and collaborate with others in an intuitive and structured way. CHASE is free and open-source software.
Our Mission
CHASE is developed by members of the German organization DMUN e.V. We aim to provide a free and accessible alternative to other debate management tools, making it easier even for smaller conferences to participate. CHASE was initially developed for German-speaking DMUN conferences – MUN-SH, MUNBW, and MUNBB – but we are open to adapting it to other conferences.

CHASE is part of the open-source initiative 'MUNify' by DMUN. This means anyone can contribute to development. We appreciate every bit of help we can get. If you have experience in web development or want to learn new skills and help out, check out our GitHub!
