Everything here is real: it’s either live, open source, or honestly labeled private. Descriptions come from the actual repos, not aspirations.
Pistahan.app — Volunteer Check-In
Liveopen source, MITOffline-first QR check-in built for the 33rd Pistahan Parade & Festival in San Francisco — 300+ volunteer check-ins through the gate in a 30-minute window, on zero budget. Volunteers pull up their own QR pass by email lookup; station scanners carry the full roster on-device, queue check-ins in an offline outbox, and sync in the background whenever festival Wi-Fi cooperates. The entire backend is a Google Sheet. Fork it for your own event.
