Event management for complex, multi-track programs
Free, open-source event management for complex multi-track events—flow control, tiered passes, fast registration, virtual credentials, and native apps.
Built for serious events
Everything you need to run multi-track programs with confidence—from first registration to last scan.
Attendee flow control
Guide how people move between tracks and sessions so venues stay balanced and every experience stays on schedule.
Multi-tiered events
Model passes, tracks, and access levels in one system—perfect for conferences with VIP areas, workshops, or parallel agendas.
Extremely fast registration
Built for moments when hundreds register at once: minimal friction from signup to confirmed seat.
Virtual credentials
Issue and verify digital passes so staff can validate access without paper chaos—online or at the door.
On-device apps
Organizer and attendee experiences on mobile, aligned with the same API and rules as your admin tools.
Async giveaways & inventory
Run item giveaways on your own timeline, distribute wins without bottlenecks, and keep a clear record of who received what while the event is live.

Tiered passes and perks
Sell or grant different access levels—swag, lounges, workshops—tied to the pass someone actually holds.
