pretix – Reinventing ticket sales for conferences, exhibitions, museums, ... | WarmIndex

pretix is a flexible, open-source ticketing platform for conferences, festivals, exhibitions, museums, workshops, and other events, handling online sales, check-in, and management.

🚀 Overview

pretix is an all-in-one ticketing software that provides a customizable online shop, box office, and check-in system for events of all sizes.

It solves the problem of rigid, expensive proprietary ticketing solutions by offering a highly adaptable, privacy-focused (ISO 27001 certified), and open-source alternative that emphasizes transparency, security, and no vendor lock-in.

pretix is built for event organizers, from small community workshops and barcamps to large trade fairs with over 100,000 visitors, including non-profits, conferences, and festivals.

The project was created to reinvent ticket sales, giving organizers full control through self-hosting options, extensibility via plugins and API, and fair pricing on the hosted service.
