Welcome on the Janus Website

Janus is an enterprise-ready open-source multi-agent platform fully implemented in Java 1.6. Janus enables developers to quickly create web, enterprise and desktop multiagent-based applications. It provides a comprehensive set of features to develop, run, display and monitor multiagent-based applications. Janus-based applications can be distributed across a network. Janus is built upon the CRIO organizational metamodel and supports the implementation of the concepts of role and organisation as first-class entities. It also natively manages the concept of recursive agents or holon.

Janus is free for non-commercial use and distributed under the terms of the GPLv3.

Janus is jointly developed by the multiagent teams of the Laboratoire Systèmes et Transports and the Centro de Investigación de Tecnologías Avanzadas de Tucumán.
