Alf.io is a free, open source ticket reservation and event attendance management system for conferences, trade shows, workshops, and meetups. It provides a public ticket shop, an organizer backoffice, check-in tooling (mobile apps and Raspberry Pi stations), and integrations with payment providers like Stripe, Mollie, PayPal, and bank transfer.

Use cases

• sell tickets for a conference online
• manage attendee check-in at a meetup
• set up a self-hosted ticket reservation system
• handle workshop registrations with payments
• print badges and scan tickets at a trade show
• avoid per-ticket fees from commercial ticketing platforms

When to choose

• you need full control over attendee data and privacy
• you want to avoid per-ticket service fees
• you run conferences, workshops, or meetups and need end-to-end ticketing
• you need offline-capable check-in stations

When to avoid

• you need a fully hosted, zero-maintenance solution
• your event is very small and a simple form suffices
• you cannot run a Java application with PostgreSQL
