Free event operations platform built for the day itself, not the weeks before it. Offline-first check-in that keeps working when WiFi drops and syncs automatically when it returns. PIN-based staff login so volunteers are operational in 30 seconds. Built-in WebRTC push-to-talk so your team stays coordinated without leaving the platform. QR check-in, bulk CSV import, seating charts, role-based staff accounts. No subscription. No per-attendee fees. No guest limits. Free.
