OpenEdition is run by OpenEdition Center (ex-Cleo, USR 2004), a non-profit public unit that brings together the Centre National de la Recherche Scientifique (CNRS), the université d'Aix-Marseille, the École des Hautes Études en Sciences Sociales (EHESS) and the Avignon Université.

OpenEdition offers the academic community four international-scale publication and information platforms in the humanities and social sciences: OpenEdition Journals, OpenEdition Books, Calenda (a calendar of events) and Hypotheses (academic blogs). These four platforms form a complete electronic publishing framework for academic research and communications. OpenEdition is a space dedicated to highlighting research, publishing tens of thousands of academic documents in open-access. 

Since 2011, OpenEdition has been complemented by a Freemium programme addressing libraries’ specific needs in a variety of formats and services.
