Offline-first reservation system that never misses a booking during Tunisian power outages
Frequent power outages in Tunisian cities cripple cloud-based hospitality apps, forcing hotels to abandon digital tools for slow, error-prone manual processes.
OutageBooker is a progressive web app (PWA) that lets hotel staff manage room availability and bookings entirely offline using local storage. When power and internet return, it automatically syncs all data to the cloud for backups and reporting. No more lost reservations or manual notebooks during blackouts.
