pretalx is a conference planning and management tool that supports organisers from call for participation through review, scheduling, and publishing the final program. It is designed for multi-track, multi-day events and is highly configurable and extensible via plugins.

Key Features

  • Configurable Call for Participation (CfP) and submission forms
  • Reviewer workflows for scoring, selection, and optional anonymised reviewing
  • Schedule planning for multi-day, multi-room, and multi-track events
  • Publishing and managing schedule releases and program updates
  • Speaker management, communication, and post-event feedback collection
  • Extensibility through a plugin ecosystem and customizable appearance

Use Cases

  • Running a conference or meetup with an open call for talks or workshops
  • Organising review committees and selecting submissions transparently
  • Building and publishing a public schedule for multi-track events

Limitations and Considerations

  • Advanced customisation beyond built-in settings may require plugin development

pretalx fits teams that need a full CfP-to-schedule workflow with strong reviewing and scheduling capabilities. It is suitable for both small community events and large conferences that require structured submissions and multi-track planning.
