Indico vs pretalx

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. For conferences, organizers can handle registration and abstract submission, store papers and other materials, and provide participant badges. Events use hierarchical categories, protections for resources, and roles within events. The room-booking module supports delegated management, booking approvals, and audiovisual equipment management. Indico integrates with Zoom so participants can join video conferences with a single click; listed plugins also cover PayPal payments and Amazon S3 event-file storage. It can be customized through configuration and plugins, and its HTTP Export API exposes category contents, events, rooms, and bookings. Indico is installed as a self-hosted instance. The project began in 2002, and CERN adopted it for event management in 2004 and has financed its development since. The maker describes room booking as suited to companies, research institutes, and universities.

pretalx manages conference calls for participation and the work that follows, including submission review, talk selection, speaker communication, scheduling, and publication. Organizers can customize call pages, set multiple deadlines, accept submissions in multiple languages, and use a chosen domain. Review teams can rate and discuss submissions, and organizers can add questions for reviewers. The schedule editor uses speaker availability and warns about conflicts; published schedules can include an RSS feed and public changelog. Organizers can use full API access or download static schedule pages for hosting elsewhere. pretalx is open-source software under the Apache License and can be installed with pip. It can be self-hosted or used as a hosted service. Self-hosted software costs nothing, but server costs and maintenance apply. Hosted service includes backups, certificates, updates, operational maintenance, and assistance; pricing is per event and varies with conference size and ticket price, with no price listed here. The hosted service says it uses servers in Germany, encrypts data in transit, and does not track attendees with cookies, analytics, or sensitive IP logging. Event-page and schedule availability is usually guaranteed for six months after an event.
