Sell tickets for £50/year with payments, QR check-in, refunds, reporting, and a hosted booking site. Self-hostable under AGPL-3.0.

Chobble Tickets is event ticketing software built around a simple pricing model: pay for hosting, not for each sale. At £50 a year or £5 a month, you get every feature, unlimited events, and zero platform commission. Ticket revenue goes straight to your Stripe, Square, or SumUp account.
It covers the full booking process from listing to check-in. You can create fixed-date, repeating, or multi-day events, each with its own capacity, pricing, booking window, custom questions, and terms. Staff can check in attendees via QR code, reverse a check-in, issue refunds, email attendee groups, and export financial or operational data. An activity log tracks every admin action.
Pricing flexibility goes well beyond a basic ticket form:
Each account includes a public-facing website for listings and content pages, with support for a custom domain and editable colours, images, and email templates. An iframe option lets you embed booking pages inside an existing site, and an order widget can turn links into add-to-cart buttons.
The software is published under AGPL-3.0-only, so technical teams can self-host it on their own infrastructure at no licence cost. Managed hosting and self-hosted installs run identical code. As a direct Eventbrite alternative, the pricing difference is stark: one organiser reported saving over £187 on a single event after switching. Chobble Tickets doesn't offer a discovery marketplace, reserved seating, or an organiser mobile app, and the site is upfront about when a competing platform might be a better fit.
