OPENPASS
What OPENPASS is
OPENPASS is a free, open-source event management platform for organizers and communities. It can publish events in a list-only format or support a fuller event lifecycle, from discovery and registration to ticketing, check-in, and feedback. People can find events through location-based calendars, an interactive map, and local trends in topics and organizers. Organizers can build event-specific registration forms with a drag-and-drop editor and text, select, and checkbox fields. The platform emails QR-code tickets and includes an offline-capable scanner that prevents duplicate scans. A real-time dashboard tracks registrations, check-ins, and capacity use, and attendee lists can be exported as CSV. Bulk email and SMS notifications are included. Paid tickets are optional and use Hyperswitch; free events need no payment configuration. OPENPASS runs on the web, through its API, or as a self-hosted deployment. The quickstart uses Docker Compose and PostgreSQL, with separate frontend and API services. The project uses the AGPL-3.0 license.
