What it is
pretalx is open-source conference software for managing calls for participation, submission review, speaker communication, scheduling, and publication. Organizers can customize call pages, set multiple deadlines, accept submissions in several languages, and use a chosen domain. Reviewer teams can rate submissions, write reviews, and answer additional questions. The schedule editor uses speaker availability and warns about conflicts; published schedules can include an RSS feed and public changelog. Organizers receive full API access and can download static schedule pages for hosting elsewhere. pretalx covers speaker management, session tracks, and room scheduling. It can be installed with pip, run on an organization's infrastructure, or used through hosted service. Self-hosting has no software charge but requires server costs and maintenance. Hosted service includes backups, certificates, updates, maintenance, and assistance. Hosted pricing is per event and not listed.
