The open source ticket reservation system

Alf.io is a free and open source event attendance management system, developed for event organizers who care about privacy, security and fair pricing policy for their customers.
It features an ecosystem of tools to cover the lifecycle of an event from ticket distribution, to event management, to reporting.
  • Alf.io web application

    GPLv3 GitHub repository

    Public, the ticket shop, where people can reserve/buy their tickets

    Alf.io supports payments through Stripe, Revolut, Paypal, Bank Transfer, as well as on-site payments. It is possible to integrate it with 3rd party tools (eg. a CRM system) through Extensions.

    Backoffice, the admin area for the event organizers

  • Alf.io Scan

    Apache2 GitHub repository

    Mobile app available for iOS and Android, which can be used by:

    • Check-in operators, to perform check-in of attendees for small events, or where on-site printing is not needed
    • Sponsors/Exhibitors, to scan attendees’ badges and collect leads
  • Alf.io-PI

    GPLv3 GitHub repository

    RaspberryPI-powered, touchscreen, offline-capable, high throughput check-in station for performing check-in for big events and printing attendees’ badges on-site.

    Upon first startup, stations form a cluster and download an encrypted list of attendees from the Alf.io instance. Data related to an attendee can be decrypted only upon scanning their ticket.
    Thanks to the resilient architecture, stations can operate offline and still guarantee that one ticket cannot be checked in twice on two different stations.

Free, as in Freedom

Alf.io is free software. You can use it whenever and wherever you want. You can also modify and redistribute it.

Secure

Alf.io has been built with security in mind. Because you care about your user’s data. It serves pages using HTTPS protocol and with strict Content Security Policy rules

Mobile Ready

The GUI has been built upon the wonderful Twitter Bootstrap framework, which is “mobile-first”. The best user experience on each device

Fair

Keep control of your event and keep attendees data away from big players. Don’t annoy them with additional fees and pay only what is really needed!

Multi-language

The GUI is currently available in Italian, English, Spanish, German, Dutch, French, Turkish, Romanian and Portuguese. Help us to translate it into your language!

PCI-Compliant

Alf.io uses Stripe as gateway for payments done by credit card. This means that no sensitive data will be stored on your server and you’ll be automatically compliant with the strictest PCI requirements.

Flexible

You can define free-of-charge as well as paid events. You can allow your users either to pre-pay the ticket by credit cardⁱ or PayPal, post-pay it by bank transfer, or even pay it at the entrance desk.

The event organizer needs a Stripe account in order to get paid. No registration is required for the attendees

Measurable

Simply create a Google Analytics™ account and configure your metrics. All the URLs are unique and let you analyze the incoming traffic. Anonymous statistics and IP-Address scrambling are enabled by default, so you are already compliant with EU “cookie law”.

Usage map:

Alf.io doesn't send any usage statistics and/or metrics to us. Because we respect your privacy.
These are the organizers we know about, and we'd love to know where are you using it, so that we can show it on the map below.

Sponsors

Open Source does not mean free of charge, it means freedom.
Although the code and the binaries might be free of charge, and therefore cheap, the time of the contributors is not.
There are some companies which are investing in alf.io, even if just for one feature, and we would like to thank them for helping the project.
