OPENPASS
OPENPASS is a free, open-source event platform for organizers and communities.
What OPENPASS is
OPENPASS is a free, open-source event platform for organizers and communities. It can publish a simple event list or support a broader workflow from discovery and registration to ticketing, check-in, and feedback. Attendees can browse location-based calendars, an interactive map, and local trending topics and organizers. Organizers can build event-specific registration forms with text, select, and checkbox fields using a drag-and-drop builder.
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 utilization, while CSV export provides attendee lists. Bulk email and SMS are included in the feature list. Paid tickets are optional and use Hyperswitch for payment orchestration; free events need no payment configuration. OPENPASS is available as a web platform, API, or self-hosted deployment. Its quickstart uses Docker Compose and PostgreSQL, with separate frontend and API services, and protected REST API routes use session-cookie authentication. The project uses AGPL-3.0, which requires publishing source changes when running a modified version as a public service. Federation, waitlists, multilingual support, webhooks, and fine-grained role permissions remain listed roadmap items.
Good
- List-only and full event-lifecycle modes
- Location-based calendars and interactive event map
- Offline-capable QR check-in scanner
- Dashboard and CSV attendee export
- Free events need no payment configuration
Watch out
- Attendee login is not available
- Several features remain on the roadmap
- Modified public-service deployments must publish source changes
Who it suits
It suits organizers and communities seeking a self-hosted event platform, especially those wanting discovery, registration, tickets, and check-in in one workflow. It can also serve groups that only need list-style event publishing.
Verdict
OPENPASS covers event discovery through check-in, with a simpler list-only mode for groups that need less. Consider its self-hosting setup and AGPL-3.0 obligations before choosing it for a public service.
