OPENPASS
OPENPASS is a free, open-source event management platform that can be self-hosted or used through web and API access. Organizers can publish events in a list-only mode or manage a fuller lifecycle covering discovery, registration, ticketing, check-in and feedback. Discovery includes location-based calendars, an interactive map and local trending topics and organizers. A drag-and-drop form builder supports text, select and checkbox fields. The platform emails QR-code tickets and provides an offline-capable scanner designed to prevent duplicate scans atomically. A real-time dashboard covers registrations, check-ins and capacity utilization, with CSV attendee export. Bulk email and SMS notifications are included. Paid tickets are optional and use Hyperswitch; free events need no payment configuration. The documented deployment uses Docker Compose, PostgreSQL, separate frontend and API services, and session-cookie authentication for protected REST routes. OpenPass is licensed under AGPL-3.0, requiring publication of source changes when a modified version runs as a public service. Federation, waitlists, multilingual support, webhook integrations and fine-grained role permissions are listed as roadmap work.
