Indico

Indico is a free, open-source tool for organizing events, archiving materials and supporting collaboration. It provides workflows for seminars, meetings, workshops and conferences, and can bring an institute’s events together. Conference organizers can manage registration and abstract submissions, store papers and other materials, and provide participant badges. Events can be grouped into hierarchical categories, with resource protections and roles set at different levels. Its room-booking module supports delegated management, booking approvals and audiovisual equipment management. Indico integrates with Zoom for one-click video-conference connections; listed plugins also cover PayPal payments and Amazon S3 event-file storage. Configuration files and plugins offer ways to customize an installation, while the HTTP Export API exposes category contents, events, rooms and bookings. The project provides installation instructions for self-hosting. Indico began in 2002, and CERN adopted it for event management in 2004 and has financed its development since. The maker says CERN uses it to manage more than 900,000 events and 200 meeting and conference rooms.
