Open source conference management
Software for submission of abstracts and preparation/management of academic conferences. This page ranks 5 open-source conference management projects by a health score recomputed every night from repository data; nothing else affects the order. motion.tools (Antragsgrün) leads at 89/100 with 319 commits in the last 90 days and 150 stars, followed by indico (83) and pretalx (82). 4 of the 5 score 70 or above, 3 publish a Docker image, and the median health is 82. MIT is the most common licence, carried by 3 of them. Between them they stand in for Eventbrite, Doodle and Slido. The score weighs commits in the last 90 days, release recency, stars, archive status and Docker support; a low number means low measurable activity, not low quality, so a finished, stable tool can legitimately sit lower down.
