Question 1

What is pretix?

Accepted Answer

pretix is a full-featured, open-source ticketing and box-office platform for events — conferences, concerts, workshops, and more. It is a self-hosted alternative to services like Eventbrite: you sell tickets, manage attendees, take real payments, issue invoices, and run door check-in, all on your own server, keeping the fees and the attendee data yourself. This install runs it on port 8307 with PostgreSQL and Redis.

Question 2

Which port does it use and how do I start?

Accepted Answer

pretix is published on host port 8307, mapped from the container's internal port 80. Open http://your-server:8307, create the admin user, then set up an organizer and your first event. Because it handles payments and personal data, you should put it behind a reverse proxy with TLS on a real domain rather than exposing 8307 directly, and make sure the public URL is configured correctly.

Question 3

Why self-host instead of using Eventbrite?

Accepted Answer

Two reasons: cost and ownership. Commercial platforms take a fee on every ticket sold, which pretix does not — you pay only for your server. And your attendees' personal data and purchase records stay on your own database instead of a third party's, which is often a GDPR requirement and a matter of principle. The trade-off is that you run and secure the system yourself, including TLS, backups, and payment configuration.

Question 4

Can it take real payments?

Accepted Answer

Yes — pretix integrates with real payment providers such as Stripe and PayPal, as well as bank transfer, so attendees pay by card or transfer through your own ticket shop. Because it processes payments, you must run it over HTTPS behind a reverse proxy with a valid certificate; never expose it in plain HTTP. It also generates invoices, which is useful for business attendees who need them.

Question 5

Is it overkill for a small free event?

Accepted Answer

For a free event where you only need registrations, yes — pretix is a full ticketing platform with a database and background workers behind it, which is more than a simple headcount requires. For that, a form builder or a scheduling tool like Cal.com is lighter. pretix earns its weight when you are selling real tickets and need ticket types, vouchers, payments, invoicing, and check-in; below that threshold, a simpler tool is the sensible choice.
