Alf.io is free software. You can use it whenever and wherever you want. You can also modify and redistribute it.
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
The GUI has been built upon the wonderful Twitter Bootstrap framework, which is "mobile-first". The best user experience on each device
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!
The GUI is currently available in Italian, English, German, Dutch and French. Help us to translate it into your language!
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.
Simply create a Google Analytics (tm) 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".
Already tested and deployed on Openshift (tutorial), Pivotal Cloud Foundry (tutorial), SAP Cloud Platform (tutorial), Heroku (tutorial), and Clever Cloud (tutorial soon)!
You can define free-of-charge as well as paid events. You can allow your users either to pre-pay the ticket by credit card(1) or PayPal, post-pay it by bank transfer, or even pay it at the entrance desk.
(1) The event organizer needs a Stripe account in order to get paid. No registration is required for the attendees

Sponsors

Open Source doesn't 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.
