Pretix

Pretix provides a self‑hosted platform for selling tickets and managing registrations for a wide range of events, including conferences, exhibitions, museums, and digital festivals. It includes an online shop, point‑of‑sale interface, access‑control integration, and support for multiple languages and payment providers. The system is designed to be flexible, allowing organizers to configure ticket types, pricing rules, and sales periods while maintaining compliance with GDPR and ISO 27001 standards.

The software is released under the AGPL‑3.0 license, offering a free tier without subscription requirements. It is intended for event organizers, venues, and institutions that prefer to run the ticketing solution on their own infrastructure while retaining full control over data and customisation. Documentation covers installation, development, and contribution guidelines, and a community forum is available for support.

Pretix has been deployed for thousands of events, processing millions of tickets, and is described as stable and ready for production use. It is positioned as an all‑in‑one ticketing solution that can be extended through plugins and integrates with hardware for on‑site access control.
